1 2 3 4 5 6 7 8 9 10 11 12 13

protectedvoidbtnsave_Click(objectsender, System.EventArgs e)         {             //connectionstrings             cnn.Open();             //insert command             cmd.ExecuteNonQuery();             stringscript = @"<script language = ""javascript"">             alert('Dear Student Your Query has been Sent to ECC.');             </script>;";             Page.ClientScript.RegisterStartupScript(this.GetType(), "myJScript1", script);             Response.Redirect(Request.Url.AbsoluteUri);                    }

 But this code is not display message before redirectting page.

I want to display message and than redirect my page as fresh form, have anyother solution for this.
