inside radGrid I have form template with asp:Button for update/insert. How can I display "please wait" after user click update/insert until it;s completed
<asp:Button ID="btnUpdate" runat="server" Text='<%# IIf((TypeOf(Container) is GridEditFormInsertItem), "Insert", "Update") %>'
CommandName='<%# IIf((TypeOf(Container) is GridEditFormInsertItem), "PerformInsert", "Update") %>'>
</asp:Button>
