Disable ASPX Submit button after click

Hi,

I have an ASPX submit button


The processing behind the click event takes a small amount of time - I want to disable the button on the client side so that the button cannot be clicked again until processing has finished ...

I've seen a few blogs on this but non of them seem to work ..

Any ideas?

Cheers,
Tim

Instead of using the submit button directly, make it non-visible.

Then, place another non-runat-server button on the page with your own onClick event handler.

In that event handler, spoof the event handler for your now-hidden button.

It usually looks something like:

__doPostback("buttonName")

You can find it by looking at your source code.

If this button is the default submit button for the form, then instead of doing that, just submit the form in your event handler:

Form1.submit();

And the part I forgot to mention:

When you take care of posting the form in your custom event handler, make sure to disable the other button...

Thanks LR - that worked a treat...

<script language="javascript">
        function ufSaveButtonClick() {                           
                  document.getElementById('btnOK').disabled=true;
                  __doPostBack('cmdOK','');                       
        }

</script>

.....


    <BUTTON id="btnOK" style="FONT-SIZE: x-small; WIDTH: 65px" onclick="ufSaveButtonClick();type="button">OK</BUTTON>
    <asp:button id="cmdOK" runat="server" Width="65" Text="OK" Visible="False"></asp:button></CENTER>
