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
