Disable a button in Javascript disables server-side code

I have a webform with an ImageButton on it. I have assigned an
OnClientScript that calls a javascript function that disables the button like
this:

<script language="javascript">
function DisableButton() {
document.getElementById("ImageButton1").disabled = true;
}
</script>

I have code-behind in the ImageButton1_Click sub that I want to process, but
that code never runs if the OnClientScript disables the button.

Is there a way to disable a button and run code-behind for it?

Disabled form elements are not included in the post data. You will have to
re-enable them onsubmit.

Sounds more like you want the button disabled after the postback. If this is
what you want you could remove your OnClientClick event handler and if you
Page_Load
event handler if Page.IsPostBack then this.btnImage.Enabled = false;
So when the page renders after processing the click event the button will be
disabled.

When you disable an asp button with client script it prevent the server side on click event from firing. What you need to do is to fire the onclick event of the button first before disabling the button. (view snippet below)

function DisableButton()
{
<%=Page.GetPostBackEventReference(ImageButton1 as Control)%>
document.getElementById('ImageButton1').disabled = true;
}
