Hi,
If you want to show UpdateProgress at the first time page load, you can check the below code.
<script type="text/javascript">
function pageLoad()
{
var updateProgress = $get('<%= UpdateProgress1.ClientID %>');
var dynamicLayout = '<%= UpdateProgress1.DynamicLayout.ToString().ToLower() %>';
if (dynamicLayout) {
updateProgress.style.display = "block";
}
else {
updateProgress.style.visibility = "visible";
}
}
</script>
