Hi Deepak,
Its so simple to delete a particular row using GridView_RowDeleting command using cell index,its good to use DataKeyName when your gridview has two deletebutton column. here i am giving code to delete row on basis of cell index. if you want code of datakeyname then tell me.
Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs)
Dim i As Integer = CInt(GridView1.Rows(e.RowIndex).DataItemIndex)
Dim rgncode As String = (GridView2.Rows(i).Cells(indexof regioncode column).Text).ToString
Dim cntrycode As String = (GridView2.Rows(i).Cells(index of countrycode column).Text).ToString
'Your delete command code gone here
GridView1.DataSource = 'name of datasource'
GridView1.DataBind()
End Sub

Hi,
What is the difference between Server.Transfer and Response.Redirect?
If possible please explain me with example.
Thanks to All in Advance.

difference between Server.Transfer and Response.ReDirect
1) Such as--Server.Transfer can not be used to go to a page of a different website whereas Response.Redirect can do.
2) Response.Redirect can be used for both .html and .aspx pages but Server.Transfer works only for aspx pages.
3) Response.Redirect needs a extra round trip...
Server.Transfer doesn't tell the browser to request page default2.aspx. It just sends page default2.aspx, so e.g., browser address bar still shows the original page's URL.
Response.Redirect sends message to browser saying that the browser should request some other page so basically it means that:
1. Browser is on page default1.aspx on which there is a Response.Redirect("") command which means that the server sends response (message) to browser that browser should request some other page default2.aspx
2. Browser sends request to server in order to get this page default2.aspx
3. Server sends page default2.aspx to browser
Roundtrip:
Roundtrip is the combination of a request being sent to the server and response being sent back to browser.
Request is the message that the browser sends to the server and Response is the message the server sends back to the browser.

one more....
Response.Redirect does not transfers the query string values and form values of the current page.
Server.Transfer allows you to transfer the query string values and form variables to other page. Best way to transfer values from one page to another using the preserveForm parameter of the Server.Transfer method.

You would help yourself if you spoke English here.
Google has tons of info on web services, they are kind of trivial to use.
