Dear Experts,

I have a Datagrid with delete options. I use to confirm from users and delete record from data grid. I give confrimation after each record has deleted when a DataGridCommandEventArgs event occured.

protected void SetDeleteButton(Object sender, DataGridCommandEventArgs e)
        {
            try
            {
                if (e.CommandName == "Delete")
                {
                    grdAdminAccount.EditItemIndex = -1;                    
                    if (e.Item.Cells[1].Text.ToLower() != "admin")
                    {
                        Management.DeleteAdmin(e.Item.Cells[1].Text, Convert.ToInt16(e.Item.Cells[0].Text));
 
                        string popupScript = "<script language='javascript' >" + "alert('The Administrator account is successfully deleted.');" + "</script>";
                        Page.RegisterStartupScript("PopupScript", popupScript);
 
                        if (grdAdminAccount.CurrentPageIndex > 0 && e.Item.ItemIndex == 0 && grdAdminAccount.Items.Count <= 1)
                        {
                            grdAdminAccount.CurrentPageIndex = grdAdminAccount.CurrentPageIndex - 1;
                        }
 
                        FileGrid();
                    }
                }
            }
 catch (Exception ex)
            {
                Response.Redirect("default.aspx?action='Error'", false);
            }      
        }

But when i am navigating to some other pages and press the back button this delete confirmation popup occured once again. How to handle it.

Please do it need full.

Regards,
Prasath

I think it has more to do with ASP.NET because I'm assuming you use Datagrid web control. Am I right? If so you should move this thread there.

TIP: When you first created your question you were asked to wrap your code with [code] tags.

It really does help a bunch. Look how much easier it is to read now that someone has done it for you. Its the button with a '#' on it. More on tags. They're cool. Check'em out.
