How To: Stop the ModalPopup Flicker
In above code PnlModal having the style="display:none;” to avoid flickering of confirmation box when page load happens
<asp:Panel ID="PnlModal" runat="server" Width="450px" style="display:none;”
How To: Avoid “Object Required” javascript error from ScriptResource.axd when popup is shown
Don’t use PnlModal.Visible = false/true; from code behind to hide/show the popup, this is not required why because ModalPopupExtender will take care this behaviour.
