Hello,
I have a web application, I am using ModalPopup extender.
I have linkbuttons inserted into gridview dynamically, upon this linkbutton click, I am passing the ID (code is shown below) and opening the popup,
Prob : Once popup is opened, if "BACK BUTTON" of browser is clicked, browser says Document expired
Note: No navigation happens till here, "Back button" of browser gets enabled when the linkButton is clicked which opens popup.
protected void lnkBtnBookTheSelected_Click(object sender, CommandEventArgs e)
{
Session["SelectedHID"] = e.CommandArgument.ToString();
Session["purpose"] = null;
if (Session["staff_no"] == null)
{
ModalPopupExtenderAuthentication.Show();
}
else
{
ModalPopup ...
Go to the complete details ...
