I am trying to get a loading panel to display during AJAX postbacks.  I have a RadGrid inside an Update Panel.  The help states "In order to have a LoadingPanel, you need to drag it to your web form from the toolbox just like any control. Then you can set a control to use a LoadingPanel using the design-time."  However, is does not explain how to "set a control to use a LoadingPanel."  Please point me to the documentation for doing this (I have been digging for a while but cannot find it.)

Thanks,
Peter

Hi Peter,

You set the RadAjaxLoadingPanel to be a default loading panel for the RadAjaxManager on the page.

http://www.telerik.com/help/aspnet-ajax/ajxajaxmanager.html

<telerik:RadAjaxManager  DefaultLoadingPanelID="......">
......
</telerik:RadAjaxManager>


Alternatively, you can set the RadAjaxLoadingPanel to be used only with certain AJAX requests (executed by the RadAjaxManager):

<AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="Button1">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="RadTextBox1" LoadingPanelID="..." />
        </UpdatedControls>
    </telerik:AjaxSetting>
</AjaxSettings>
