What is ASP.Net

ASP.Net is a server side scripting technology. It is a developent framework for building web pages and web sites with HTML, CSS , JavaScript and server side scripting. Server side scripting means code can be executed by the server , not in the client browser. So that we can use compiled code that can be run at the server. Hence ASP.Net provides increased performance by running compiled code.

There are many differences between the classic ASP and ASP.Net.

Difference between ASP.Net and ASP

ASP.Net

1. ASP.Net webforms can have code behind file for event handling code. That is seperate code and design logic is possible ( .aspx and .cs )
2. ASP.Net webforms inherit the class written in code behind.
3. ASP.Net web applications are configurable. That is web.config file can be used for configuring the application.
4. ASP.Net is object oriented. That is OOPS concepts are implemented in asp.net.
5. Complete session and application state management.
6. ASP.Net webforms have ADO.Net and full XML support for easy data exchange.
7. Variety of compilers and tools are available.
8. Custom controls can be used with the help of @Register directive.
9. Many languages can be used for programming ( C#, VB.Net, J# etc ).

ASP

1. In ASP, code and design cannot be in separate files. That is it have mixed HTML and code logic.
2. Only a limited OOPS support. For example, Inheritance is not available.
3. ASP uses scripting languages like Jscript or Vbscript.
4. Only a limited development and debugging tools are available.
5. Custom controls cannot be possible with ASP.
6. Limited session and state management.

How To split a string in SQL Server

SQL Function For Spliting a String in SQL SERVER

In SQL Server we do not have a built in function for splitting a string with any character. So we need to write the query for splitting a string in SQL. Here I am creating a function for splitting a string and getting the output data in a table.

CREATE FUNCTION [dbo].[fnSplitString] ( @MyArray VARCHAR(8000), @separator CHAR(1) )

RETURNS @RetTable TABLE

(StrValue VARCHAR(256))

BEGIN

DECLARE @SeperatorString VARCHAR(10);

SET @SeperatorString = '%' + @separator + '%'

DECLARE @separator_position INT

DECLARE @array_value VARCHAR(1000)

SET @MyArray = @MyArray + @separator

WHILE PATINDEX( @SeperatorString , @MyArray) <> 0

BEGIN

SELECT @separator_position = PATINDEX(@SeperatorString , @MyArray)

SELECT @array_value = LEFT(@MyArray, @separator_position - 1)

INSERT @RetTable VALUES ( CAST(@array_value AS VARCHAR(256)) )

SELECT @MyArray = STUFF(@MyArray, 1, @separator_position, '')

END

RETURN

END

This will create a new function. Now you can easily pass parameters to this function and get the data in a table format. Parameters are

@MyArray - The full string which we need to split

@separator - The character by which we need to split

Here are some examples

Example 1 :

SELECT StrValue FROM dbo.[fnSplitString]('data1,data2,data3,data4',',')

The result will be

Here the separator is comma( , ).

Example 2 :

DECLARE @MyString VARCHAR(1000);

SET @MyString = 'data1;data2;data3;data4;1;2;3'

SELECT StrValue FROM dbo.[fnSplitString](@MyString,';')

The result will be

Here the separator is semi-column(;)

Thanks for reading my post. Happy Coding. :)

How to make the header of a grid fixed ( Freeze Header )

Hi All..

In this post I will tell you how we can make the header of a grid fixed( freezing the header). Most of us are using grid control for displaying the data in a grid view structure. It is a powerful control by the .net frame work. But there are some limitations for it. I am not going to tell you the limitations. But One of the limitation of grid control is that header of the grid is not fixed. If we are displaying a large amount of rows, we need to make the grid scrollable.But the problem is that the header of the grid also get scrolled. So at the end of the rows , user will not get an idea about which is the data corresponding to each column.

Here I am going to show how to make this possible. I am not using the grid control. I am using only html controls- div, table, css and jquery. Here I will give you only a simple structure of the html - how to make the header freeze and the content rows scrollable It is a simple structure. If you want to know what should be the structure to make this posssible, you can continue reading. If you want to know and need to bind dynamic datas to this grid( from datatable or some other souces) and make it scrollable, you can refer the new post here. If you want to know how to dynamically bind data to this structure from database tables, you can see more details here.

So let us start with this.

Here I am using 2 divs, 2 html tables, css and javascript(jquery).

Step 1.

Copy and paste the following html codes into your .aspx or html page.

<div>

<td class="ClsProduct1" >Product Name</td>

<td class="ClsProduct1" >Product Code</td>

<td class="ClsProduct1" >Product Type</td>

<td class="ClsProduct1" >Price</td>

<td class="ClsProduct2" >Number</td>

</tr>

</table>

</div>
