Last but not the least , i did it my self :
Solution is :
1 - Use timer control ,set it's property to enabled = false , and ontick event redirect to same page ...
Here's how it is done :
<asp:Timer ID="RedirectTimer" Interval="3000" OnTick="RedirectTimer_OnTick" Enabled="False" runat="server"></asp:Timer>
protected void ProjectGRID_OnRowDeleted(object sender, GridViewDeletedEventArgs e)
{
RedirectTimer.Enabled = true;
}
protected void RedirectTimer_OnTick(object sender, EventArgs e)
{
Response.RedirectToRoute("ProjectMaker");
}
THATS CALLED :::: JUGAAR -- TRICK ---
