Hi,

Try the following code Snippet to show RadAjaxLoadingPanel on clicking the RadToolBarButton.

JS:

<script type="text/javascript">

var currentLoadingPanel = null;

var currentUpdatedControl = null;

function RequestStart(sender, args)

{

currentLoadingPanel = $find("<%= RadAjaxLoadingPanel1.ClientID%>");

if (args.get_eventTarget() == "<%= RadToolBar1.UniqueID %>")

{

currentUpdatedControl = "divDataEntry";

currentLoadingPanel.show(currentUpdatedControl);

}

function ResponseEnd()

{

if (currentLoadingPanel != null)

{

currentLoadingPanel.hide(currentUpdatedControl);

}

currentUpdatedControl = null;

currentLoadingPanel = null;

}

</script>

C#:

protected void RadToolBar1_ButtonClick(object sender, Telerik.Web.UI.RadToolBarEventArgs e)

{

System.Threading.Thread.Sleep(500);

}

Thanks,
Princy.
