An easy way to construct the Connection String in ASP.Net

By Francis   Posted at   7:26 AM   Connection String 2 comments

Connection strings are necessary when you want to interact with any databases like SQL Server, MSAccess etc. Most probably if you are using ADO.Net Concepts to interact with Database then you can aware about the connection string. In this article I am going to share how it can be easily constructed.


Step 1:

Open Visual Studio and create sample web form application.


Step 2:

Switch over to “Design Mode” and in the tool box, just drag and drop a “Gridview” control in to the web form.



Step 3:

Select “New Data Source”.


Step 4:

In the “Data Source Configuration Wizard”, select your database click “OK”.


Step 5:

In the next step of the wizard, Click “New Connection”.


Step 6:

It will provide a pop-up dialog box to select “Data Source”, in that select “Data Source” and select data provider from “Data Provider” dropdown list, then click “Continue”.


Step 7:

In “Add Connection” modal dialog, select your “Server Name” (if not available, first click “Refresh” button, still it not available type your “SQL Server Name” manually on it).

You can either use, “Windows Authentication” or “SQL Server Authentication” to login to your SQL Server.

As a next step, select your database, that is available on your SQL Server. Finally, click “Test Connection”, to check whether the connection is established successfully or not.




Step 8:

As a final step, you will get the Connection string, which can be used on your web/windows application to connect the DB.


Happy Coding!

ASP.Net MVC – Create Custom HTML Helpers

By Francis   Posted at   11:52 AM   Razor No comments
Html Helpers are classes that helps to render HTML controls in Views. We can also create our own HTML Helpers. In this post, I’m going to explain how to create a simple Custom HTML Helper. The main purpose creating custom HTML helper is reuseability.

Step 1:
          Create a static class and add method to it like below.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MVCTutorial
    public static class CustomHTMLHelper
        public static MvcHtmlString ImageLink(string action, string controller, string imgageURL)
            // Create a link with an image
            return MvcHtmlString.Create(String.Format("<a href=\"{1}\\{0}\"> <img src=\"{2}\" /></a>", action, controller, imgageURL));

Step 2:
          Access the custom helper class in a View.
<!DOCTYPE html>
    <meta name="viewport" content="width=device-width" />
        @CustomHTMLHelper.ImageLink("Home","Account","your image url")

The helper class is static, since it can be called in a easy manner also handy.
Happy coding!

Design Pattern - An Introduction

By Francis   Posted at   5:08 PM   Design Pattern No comments

                                  Few weeks ago, I commit to take an session about design pattern in my organization. As a matter of fact, I’m not a big fan of design pattern. However, I began dwell with design pattern, I found interesting on it. So I decided to write some posts on it. In this post, I just give an introduction about design pattern.
So what is design pattern?

                                 Design Pattern are conceived by the 4 people who wrote the book "Design Patterns: Elements of Reusable Object-Oriented Software ".  Design pattern is a proven ways to solve the particular problem while arising often writing software programs. Those problems are frequently encountered by the programmers, most probably when design the software.  So there is no reinvent the well again. There are 23 solutions predefined by the above authors. Each problem has its own name also.
The ultimate goal:
There is no reinvent of solution for the 23 problems. Also the main benefit is maintainability of software. If you want to change something in the existing system it is so easy. The above are the main benefits of design pattern. These 23 design patterns are called Gang Of Four in general.
                           They are categorized into 3 types. They are: 1. Structural Pattern 2. Creational Pattern 3. Behavioral Patterns

The category name itself enough to explain, the purpose of each pattern. For example, Creational patterns are talk about the object creation. At the same time structural pattern described about code structure. Below are the 23 design patterns.


Creational Patterns:

  1. Abstract Factory
  2. Singleton Pattern
  3. Builder Pattern
  4. Factory Method Pattern
  5. Prototype Pattern


Structural Patterns:

  1. Flyweight Pattern
  2. Proxy Pattern
  3. Adapter Pattern
  4. Bridge Pattern
  5. Facade Pattern
  6. Composite Pattern
  7. Decorator Pattern
  • Behavioral Patterns:
    1. Chain of Responsibility
    2. Observer Pattern
    3. Command Pattern
    4. Interpreter Pattern
    5. Iterator Pattern
    6. Visitor Pattern
    7. Template Pattern
    8. Strategy Pattern
    9. Memento Pattern
    10. Mediator Pattern
    11. State Pattern

How to disable the “tooltip” for a control programmatically?

By Francis   Posted at   12:31 AM   ASP.Net with Javascript No comments
One of the forum member ask this question in the forum. The answer is yes, we can use a simple javascript to achieve this functionality. Take a look at the below code:
Using Javascript:
<html xmlns="">
<head runat="server">
    <script type="text/javascript">
        function DisableToolTip() {
            // Get the object
            var obj = document.getElementById('LnkBtn');
            // set the tool tip as empty
            obj.title = "";
    <form id="form1" runat="server">
    <asp:LinkButton runat="server" Text="Simple Link Button" ToolTip="Simple Button with Tool Tip" ID="LnkBtn" ClientIDMode="Static" ></asp:LinkButton>
    <a href="#" id="lnkDisable" onclick="DisableToolTip();">Disable Tool Tip</a>

Using JQuery:
<html xmlns="">
<head runat="server">
    <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("#lnkDisable").click(function () { $('#LnkBtn').attr({'title':''}); });
    <form id="form1" runat="server">
    <asp:LinkButton runat="server" Text="Simple Link Button" ToolTip="Simple Button with Tool Tip" ID="LnkBtn" ClientIDMode="Static" ></asp:LinkButton>
    <a href="#" id="lnkDisable">Disable Tool Tip</a>

ASP.Net Forums - FAQ #5: How to change the Title Case of a string to Uppercase in Server Side?

By Francis   Posted at   12:04 PM   ASP.Net Forums No comments
One of the user in the forum asked similar to this question. In server side, I thought take the string, and covert it to character array and loop thru the character and change the first Letter alone to capital letter.
                     Instead,we can use “TextInfo” class to achieve the solution in a easier manner. The below function used to convert the given string’s first character alone as a Capital letter.

        using System.Globalization;
        using System.Threading;
        public string changeName(string inputname)
            string modifiedname = string.Empty;
            string[] names = inputname.Split(' ');
            foreach (string name in names)
                    CultureInfo cultureInfo   = Thread.CurrentThread.CurrentCulture;
                    TextInfo txtinfo = cultureInfo.TextInfo;
                    string temp=txtinfo.ToTitleCase(name);
                    modifiedname = string.Concat(temp, " ");
            return modifiedname;

Daily interview Question #10 : what is the purpose of "explicit" implementation of interface?

By Francis   Posted at   7:32 AM   CodeProject No comments

There are 2 purposes of explicit implementation of Interface:
First, it is used to avoid name collision between interface methods. That is if you are going to create a class library, there may be a chance to use the same name in several places. At that time "explicit" implementation comes as a rescue.
Secondly, You cannot access that implemented method through the object of the class directly. Instead you typecast it as Interface reference then you can access it. This is because, the C# complier, unable to determine which one the user want to call.

Daily interview Question #9: what is the purpose of ref and out parameters in C#?

By Francis   Posted at   9:00 AM   No comments

          Ref keyword is used to send the particular parameter as a reference to the function or subroutine.
          In some cases we may want to return value from the function but we don't want to use that variable within the function. We just get back some value, that's all. In these kind of scenarios we may go with 'out' parameter.
          The main difference between the two is, before passing ref parameter we must initialize the particular variable. But this kind of initialization is not necessary with 'out' parameter.

ASP.Net Forums - FAQ #2 : ASP.Net Project Ideas

By Francis   Posted at   8:17 AM   ASP.Net Forums No comments
                                              ASP.Net Forums have tons of Questions. I have preferred some most frequently questions and give a detailed explanation here. This one also I encountered a lot in the ASP.Net Forums. Most of the college students and beginners are asked about the below questions:
How to start an ASP.Net Web Projects?
Where to get some basic ideas about web based projects?
                    In this post I just want to guide those people from my practical experiences.

Prerequisite – Software:
                Before start your project you need the below softwares:
  1. Visual Studio
  2. .Net Framework
  3. SQL Server   
                        For students and beginners express version of visual studio is enough. While this writing Microsoft released Visual Studio 2013. You can download the Visual Studio 2013 express for web development here. With that installation, .Net framework 4.5 also installed. So there is no separate download is not necessary.
                         Each and every website that are developed are data centric or data driven. That are data are stored and retrieved from a database like SQL Server. So you must need that one also.
                         For SQL Server also Microsoft provide express version. You can get it SQL Server 2008 Express with SP2 here and SQL Server 2012 here.
                        For the above software installation you must need Windows 7 with SP1 or Windows 8.
Prerequisite – Skills:
              The below are the must have skill sets that are required for every beginner in ASP.Net.
  1. .Net Architecture (CLR and BaseClass Library)
  2. C# or VB.Net Language
  3. ADO.Net
  4. ASP.Net (Web Form, Worker Process, AppDomain, Session, Cache, Authentication etc)

               It is better how the .Net frameworks works which helps to the developer to grasp the rest of the things easily. If you want to go with ASP.Net you should learn any one of the .Net compatible language such that C# or VB.Net. ADO.Net always deals with Database related objects like Datasets, Datatables etc. In beginner level choosing Web Form will give a easy to move way in ASP.Net. The above lists are specific to .Net.

Some Good Books for ASP.Net:
         Below are my personal suggestion to sharpen your skills in ASP.Net as well as .Net Languages such as C# and VB.Net in some extend.

  1. Programming ASP.Net By Dino Espotio (From Microsoft Press)
  2. Professional ASP.Net 2.0/3.5/4.5 (from wrox publications)
  3. C# 4.0 – The Complete Reference By Herbert Schildt

Online Tutorials & Trainings for ASP.Net:
               For ASP.Net technology, there are so many good online tutorial sites available. Some of them for your reference:

What do you think?
                  The above are my professional experience, that I have earned over lot of time. Do you want to say something, please let me know thru comments.

Daily Interview Question #8 : What are the efficient ways to show million records in a page?

By Francis   Posted at   1:27 PM   No comments

The below answer is my own suggestions that I gave as an answer.

                  In practical there is no need of pull million of records at one call. Instead of that we can show 10 or 100 of records in the web page with pagination. To pull the records from Database, just write a stored procedure it will also contains the pagination logic. That is, if the second page clicked, the stored procedure pull the rows from 101 to 200.

The above method consist 2 advantage:

1) Increased performance (only we pull and show 100 records).

2) Faster retrieval.

Daily Interview Question #7: Implicit and Explicit Implementation of Interface

By Francis   Posted at   12:22 AM   OOPS interview Questions No comments

                                                   This is the most common interview question for experienced professionals.

Normally an interface can be implemented in a class in a normal way which is a implicit implementation. Sometime, we may have same method name in different interfaces. If this is the case, we need to do explicit implementation of the interface method. The main use of explicit implementation is to avoid the ambiguities between the class or method name. In order,  to do that the interface name put before that interface’s method.


Below example, shows the implicit and explicit implementation:


namespace ConsoleApplicationC
    // 2 interfaces with same method name
    interface IintegerAdd
        void Add();
    interface IfloatAdd
        void Add();
        void Multiply();

    // We implement Both interfaces
    class ArithmeticOperation : IintegerAdd, IfloatAdd
        // Implicit  Implementation : There is no name collision so we can implement implicitly
        // NOTE : public modifier MUST here
        public void Multiply()
            float a = 1.5f, b = 2.5f;
            Console.WriteLine("Float Multiplication is:" + a * b);

        // Explicit Implementation :  Explicitly tell the compiler that we implement the interface IintegerAdd
        void IintegerAdd.Add()
            int a = 10, b = 20;
            Console.WriteLine("Integer Addition Is:" + (a + b));

        // Explicit Implementation :  Explicitly tell the compiler that we implement the interface IfloatAdd
        void IfloatAdd.Add()
            float a = 1.5f, b = 2.5f;
            Console.WriteLine("Float Addition Is:" + (a + b));
    class Program
        static void Main(string[] args)
            ArithmeticOperation objA = new ArithmeticOperation();
            IintegerAdd iobj = (IintegerAdd)objA;
            IfloatAdd fobj = (IfloatAdd)objA;

Output :


Integer Addition Is:30
Float Addition Is:4

Visual Studio Tips & Tricks - 8: Breakpoint will not currently be hit. No symbols have been loaded for this project.

By Francis   Posted at   5:50 PM   Visual Studio Tips and Tricks 2 comments

Most of the developers who are using Visual studio have encountered the above problem. As a ASP.Net Developer I have this atleast once a day. So the below are my tricks to get ride of this issue.


1) Just Close the VS IDE.

2) Go to Task Manager and kill the worker process. (If you are working on  ASP.Net application).

3) Go to the .Net installation folder ( Normally it should be C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files OR C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files) and clear the temp files from the temporary folder.

4) Open the solution and "Rebuild" entire solution. Now try to attach the debugger.


Please note that, in some machines you may have 2 framework installation, one for 32-bit and another for 64-bit. So when you go with step 3, pay close attention and make sure which .net framework was used and also which version no (either 2,3,3.5 or 4) was used by your application.


Hope this helps!

Using MSCaptcha

By Francis   Posted at   9:08 PM   MSCaptcha No comments

                                    Recently, in one of my project I need a captcha for my application. Just a google search provides number of options. I need a open source solution, so I go with krisanov’s solution. I just download and try to using that on my project. However it doesn’t works fine. Just follow the instruction mention by mudasar in this url. But I have encountered several problems (that is it doesn’t display any captcha image) the when I added that into my project, which leads to write this post.

Below are the steps that I have followed:


1) Just download the captcha from the url.

2) Add the reference into the project by “Right Click on the Project –> Add Reference”.

3) After that you need to include the below lines into web.config file:


        <add verb="GET" path="CaptchaImage.aspx" type="WebControlCaptcha.CaptchaImageHandler, WebControlCaptcha"/>

<location path="CaptchaImage.aspx">
            <allow users="*"/>


What previously done, I have missed out entire “location” element, which is also not mentioned in the mudasar’s tutorial. I have found this solution in this forum thread.

Hope this helps to someone!

VisualStudio Tips & Tricks - 7 : Using Transact-SQL Editor in Visual Studio 2010

By Francis   Posted at   10:13 AM   Visual Studio Tips and Tricks No comments
                           Few months ago, when we upgrade from VSS to TFS, somehow we lost intellisense in SQLServer Management studio 2008 R2. We struggle a lot to obtain. But no luck till now. However, currently we are using Visual Studio 2010, which enriched with lot of futures.
            Instead of using SQL Server Management, what I did was open the SQL file using Visual Studio 2010. In Visual Studio, Right click on the Menu bar, from the floating menu “check” the “Transact-SQL Editor”.

Now we got the toolbar available in SQL to do some basic operations like connect the SQL Server, Execute the Transact SQL etc., The main benefit in this approach is the intellisense works fine with in the “Transact-SQL Editor”. So my problem solved temporary.
One of the main attraction in this feature is, we can do all basic operations with in this editor. However, I’m not at all a DBA, just a developer who used SQL server as a backend. This is more convenient way work as of now.

Hope this may help to some one!!

Visual Studio Tips & Tricks – 6 : Multi-Copy functionality in Visual Studio

By Francis   Posted at   12:26 PM   Visual Studio Tips and Tricks No comments

                                    Some time we may need to copy the multiple code snippets (that is we may need to copy and paste lines that are not in order) in a file and paste it in another location of the file inside Visual Studio. For example, we have 5 lines of text, what we need is to copy the 1,3 and 5 line of text and paste it on some other location. To achieve that functionality to do the following:


1) Copy the code snippets using Ctrl+C key combination. (That is select the line 1 and press Ctrl + C and select line 3 press Ctrl + C and so on).

2) When you paste that code press the key combination Ctrl + V + Shift key, which rotates the copied lines of text. To paste a particular selected text just press Ctrl + V.


Hope this helps to some one!

Attach Javascript to Button

By Francis   Posted at   2:01 PM   No comments

In this tutorial I’m going to explain how to add a javascript snippet to the ASP.Net server side Button Control.



Copy the below code in an .aspx file:


<html xmlns="">
<head runat="server">
<form id="form1" runat="server">
<asp:Button runat="server" ID="btnSubmit" Text="Click Me" />


Copy the below code in an .aspx.vb file:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
btnSubmit.Attributes.Add("onclick", "alert('Button Clicked');return false;")
End Sub


The above code add “onclick” attribute to the Server side button “btnSubmit”. The attribute value is just a javascript snippet, which just show an alert box.


Take a look, after the alert we specify the “return  false;” which avoid the webform to be refreshed.


Hope this helps!

Daily Interview Question #5 : What is the difference between “Method Overloading” and “Method Overriding”?

By Francis   Posted at   1:47 PM   OOPS interview Questions No comments

Method overloading

Method overriding

method overloading used to achieve “early binding” or “static binding”. method overriding used to achieve “late (dynamic) binding” or “runtime polymorphism”.
method overloading means, in a class method can be declared with same method name and with different parameters. method overriding means, a method defined in base class can be redefined in the derived classes.
method signature (method name + parameter) must be different in method overloading. method signature must be same in method override.


Sample Program:

using system;
using system.collections.generic;
using system.text;

namespace consoleapplicationc
//Base class
class baseclass
private int add(int a, int b)
return a + b;
// Overload the Above Method
private float add(float a, float b)
return a + b;
// virtual method - Indicates this will be override in Child class
public virtual string whereiam()
return "In Base Class";
// Derived Class
class derived : baseclass
// Base class Method Override here
public override string whereiam()
return "In Derived Class";
class program
static void main(string[] args)
// Just create base class reference
baseclass basereference;
// Create Base class Object
baseclass baseobj = new baseclass();
// create object for Derived class
derived derivedobj = new derived();
// Base class reference contains derived object
basereference = derivedobj;
// Now Derived class method called with base ref
string strvalue = basereference.whereiam();
// Now Base class ref contains base object
basereference = baseobj;
string strval = basereference.whereiam();
in derived class
in base class

Daily Interview Questions #4: What is the difference between Abstract Method and Virtual Method?

By Francis   Posted at   1:29 PM   OOPS interview Questions No comments

Abstract Method:

Abstract method specified by “abstract” keyword.

An abstract method contains no definition. Derived class must implement the abstract methods.

Object cannot be created for abstract class. That is abstract class can not be instantiated.

Virtual Method:

Virtual method specified by “virtual” keyword.

Used to implement “Run-Time” polymorphism.

Derived classes not forced to implement the “Virtual” methods that is available in Base class.

The process of redefine the virtual method in a derived class called as “Method Overridding”.
