I have a RadGrid inside a Panel, inside a User Control. In the RadGrid is a RadComboBox in a GridTemplateColumn. When the user selects a value from the RadComboBox it fires a postback to automatically populate the next column. The problem here is that although it fires an Ajax Request, the loading panel doesn't display. The page appears ready to use the entire time. I've tryed configuring the AjaxSettings every way I can think of. I've set the combo box as the ajax control with the grid as the updated control, the grid and the panel, the panel and the panel, every possible combination; but the loading panel will not show up. Here's the current Ajax Settings:
<
telerik:AjaxSetting
AjaxControlID
=
"radGridGovernanceWithin"
>
<
UpdatedControls
>
<
telerik:AjaxUpdatedControl
ControlID
=
"radGridGovernanceWithin"
LoadingPanelID
=
"RadAjaxLoadingPanel1"
/>
</
UpdatedControls
>
</
telerik:AjaxSetting
