if you need to clear the session on popup close in your CloseButtonClick event, then you can use a hidden button on your page and fire that event using javascript to clear your session like below:

1.Add CSS in your page

   <style>.hidden { display: none; }</style>

2.Add this script

   function ClearSession() { document.getElementById(btnHidden).click(); }

3.Add a hidden control like this one

   <asp:Button ID=btnHidden runat=server CssClass=hidden 

                 OnClick=Button1_Click ClientIDMode=Static />

4.Add this one in your code behind

   protected void Button1_Click(object sender, EventArgs e) { Session[smn] = null; }

Now on your control you just need to call the javascript above, pretty much the same as yours:

   <ClientSideEvents CloseButtonClick=ClearSession() />
