URL rewriting is the process of intercepting an incoming Web request and automatically redirecting to another URL.
To understand completely?follow below link

I have a few minutes, to learn how to achieve URL rewriting, I'll be in a simple example, in this article.
I believe developer doesn’t have much time to read a complete article of 20 pages.
Here we go
Step 1
Create a table
(
POSTID INT,
TITLE VARCHAR(255),
BODY TEXT
)
CREATE TABLE TESTTABLE
Insert some dummy values
INSERT INTO TESTTABLE (POSTID,TITLE,BODY) VALUES (1,‘ACCORDIAN CONTROL WITH SQL SERVER’,
‘ACCORDIAN CONTROL WITH SQL SERVER CONNECTIVITY JOGGEE
MADE A ARTICLE AND THAT IS THE BEST I THINK SO.’)
GO
INSERT INTO TESTTABLE (POSTID,TITLE,BODY) VALUES (2,‘Mouse over effect’,
‘This is so simple and can found thousand places but I tried to make it more easier who
doesnt know the different between or anchor.’)
GO
?
SELECT * FROM TESTTABLE
STEP – 2
Create a stored procedure
Create PROCEDURE PROC_TEST
AS
BEGIN
SELECT
‘’ + TITLE + ‘’ AS ‘TITLE’,
BODY
FROM TESTTABLE
END
GO
Procedure for Detail Page.
CREATE PROCEDURE PROC_TESTDETAIL
@ID INT
AS
BEGIN
SELECT
POSTID,
TITLE,
BODY
FROM TESTTABLE
WHERE POSTID = @ID
END
GO
Database work is finished, let move to ASP.NET project means Website Programming.
Create a Website, Ajax Enabled or not its up to you, No matter what you choose.
In the default Web page to write the following code. I pasted the complete code for the default page. Where do I direct use of DataList, there are two areas of binding.
In a Code Behind Past below code.
Imports System.Data
Imports System.Data.SqlClientPartial Class _Default
Inherits System.Web.UI.PageProtected Sub Page_Load (ByVal sender as object, e ByVal As System.EventArgs) Me Handles
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me .Load
If IsPostBack = False Then
Dim sqlConn As New SqlConnection
Dim sqlCmd As New SqlCommand(“PROC_TEST”, sqlConn)
Dim objDA As New SqlDataAdapter
Dim DT As New DataTable
‘******************************************************************************************************
‘I have mentioned this connection string in the web.config Change it with appropriate values.
‘
‘****************************************************************************************************************
sqlConn.ConnectionString = ConfigurationManager.ConnectionStrings ( "connString's"). The ConnectionString
‘opening a connection
sqlConn.Open()
sqlCmd.Connection = sqlConn
sqlCmd.CommandType = CommandType.StoredProcedure
objDA.SelectCommand = sqlCmd
‘populate data table
objDA.Fill(DT)
‘bind data
DataList1.DataSource = DT.DefaultView
DataList1.DataBind()
‘disposing all the declared objects.
objDA.Dispose()
objDA = Nothing
sqlConn.Close()
sqlConn = Nothing
sqlCmd.Dispose()
sqlCmd.Connection.Close()
sqlCmd = Nothing
End If
End Sub
End Class??
Code for Detail WebPage.?
Create a folder named
In a Code Behind Just Copy Paste
