Hello daw,

Could you please elaborate a bit on your scenario and the functionality you are trying to achieve?

I suggest that you check out this online demo on how to show loading panel over client-side bound grid.
Give it a try and let me know how it goes.

Hello daw,

The approach show in this help topic is more applicable for server-side bound grid.
The best solution for showing loading over the client-side bound grid is shown in the previously mentioned online demo. Could you please confirm it is not suitable for you?

ok I have idea add
$find('<%= Master.FindControl("RadAjaxLoadingPanel2").ClientID %>').show('<%= Master.FindControl("Panel1").ClientID %>');
in pageLoad
and after data bind:
$find('<%= Master.FindControl("RadAjaxLoadingPanel2").ClientID %>').hide('<%= Master.FindControl("Panel1").ClientID %>');
and is ok:)
