How to fire up an UpdateProgress ?

I have an updateprogress (code below) as follows and it is displaying the gif correctly when the database is loading.
However, I also want this gif to display when the page is first loading.
What is the code to put in Page_Init to fire up this ?
I tried UpdataProgress1.databind()
and it turns error. What should be the code of it ?
Thanks


<asp:UpdateProgress ID="UpdateProgress1" runat="server">                  <ProgressTemplate>         <asp:Image ID ="image1x"  runat="server"  ImageUrl="~/wait.gif" />                  </ProgressTemplate>                 &nbs ...
