Hi,
I have a server side form button with id btnsubmit
As the form is big, the submission process is slow.
A user may click on the button many times, I want to prevent that by
client-side code.

I made this function:

<script language="javascript" type="text/javascript">
function Disable()
{
   document.getElementById("btnSubmit").disabled = true;
}
</script>

then in the button server html I added  OnClientClick=""

<asp:Button ID="btnSubmit" runat="server" CssClass="Body"
OnClick="btnSubmit_Click"
                                           Text="Save And Continue!"
OnClientClick="Disable();" />

But the result was that the button is disabled once I click it and doesn't
make its server side code duties.

Any Help Please...
