Show and Hide Modal Popup Extender Not working

Hi all I have a modal popup extender set to a hidden linkbutton. So when I want to use it I am doing

protected void ProcessFileBtn_OnClick(object sender, EventArgs e)
{
    WaitModalPopupExtender.Show();
    //DO STUFF
    WaitModalPopupExtender.Hide();
}

Process takes a while, but no Modal Pop Up extender shows, when I create a button just to do the show function it works, but when I add in this

protected void Test_Click(object sender, EventArgs e)
{
    WaitModalPopupExtender.Show();
    System.Threading.Thread.Sleep(5000);
    WaitModalPopupExtender.Hide();

}

Nothing shows up. Any thoughts?

It won't work. Why...?? First request sent to Server.

WaitModalPopupExtender.Show();----Executed---But no response send to Client
System.Threading.Thread.Sleep(5000);----Executed---But no response send to Client
WaitModalPopupExtender.Hide();----Executed---Now its time to send the response

Now you can expect the output that will be sent to the Client

Without seeing all of the code it's hard to tell, but I believe that the page is doing a PostBack when you click the linkbutton. When the page does a postback, it refreshes and therefore your ModalPopupExtender won't show. I think you're looking for and Ajax call to do what you want, which I'm pretty sure is showing a wait window while processing data.
