You can't. The best you can do is to save the html files it generates, and then modify them so that all the links on them link directly to other html files you have created. No postback is going to occur, how successful this can be would depend entirely on how static your site is. If it has a forum, for example, forget it.

.NET manages the garbage collection automatically. You don't have to worry about clearing the objects. This will be done by .NET runtime automatically. But some classes implements IDisposable interface, which should be disposed by calling Dispose() method manually.

For this you need to keep one primary column on your datatable. When binding to gridview make this column to invisible. Eventhough it is invisible, you can access it by specifying the cell. So when delete button got click, you need to find out this hidden value. This will be the key for the record to be deleted.

Thanks for the reply but
I know these whole things, the problem is i am unable to got that id feild at runtime when i click on the delete button in perticular row.

use DataKey property of the gridview to access the ID value and to delete a particular record set the Command Property of the Delete Button as "Delete" and use GridView.RowCommand Event and put your delete code there...

Did you set the datakeynames property in the GridView? something like this...
asp:gridview id="GridView1" datasourceid="GridView1Source" <br />
autogeneratecolumns="true" datakeynames="ID" runat="server">
If yes then In the GridView.RowCommand Event you can access the ID value using the below statement
GridView1.DataKeys[rowIndex].Value
try this...

Try this:
Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
Try
Dim oGridViewRow As GridViewRow
oGridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)
ID = CInt(GridView1.DataKeys(oGridViewRow.RowIndex).Value)
If e.CommandName = "DeleteTrans" Then
DeleteRecord(ID)'Function for delete the selected record
BindGridView()'Bind Gridview again
End If
Catch ex As Exception
End Try
End Sub
Hope this helps u??

you have to give a primary key field as datakey field of datagrid.
asp:DataGrid ID="dgrdProducts" DataKeyField="ProductID" OnDeleteCommand="dgrdProducts_DeleteCommand" Runat="Server"
.
.
Then in code file
void dgrdProducts_DeleteCommand( Object sender, DataGridCommandEventArgs e )
{
int intProductID;
intProductID = (int)dgrdProducts.DataKeys[e.Item.ItemIndex];
}
using intProductID you can delete record from database.
