Hi There,

I run into an issue that the loading panel is not showing with RadScheduler. I created a test page from the code of the telerik demo, it stills not showing the loading panel, just showing flashes between the postback (when changes the monthview to weekview etc). Please help. Thanks.

Following the the code of SchedulerTest.aspx, and SchedulerTest.aspx.cs

The demo code is from the following link, but the loading panel in my test page is not working the same as the demo shows:

Hello Meng Li,

You have to set a skin to the LoadingPanel, for example:
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">
</telerik:RadAjaxLoadingPanel>

If a skin is not set to the LoadingPanel you can make a selection in the RadSkinManager's Chooser. After the selected skin is applied to the Scheduler and the LoadingPanel it will display the loading icon that corresponds to that skin when the Scheduler initiates an ajax request, for instance when you double click an appointment to edit it.
