I need a cascading dropdown effect with the comboboxes at the bottom of my page, With no ajax, it works as desired, but when I enable ajax I see the loading image and then nothing happens. What settings do I need to get this to work?

Hello Ken Miller,

Could you please try adding the following Ajax settings:
<telerik:AjaxSetting AjaxControlID="MascotPanel">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="MascotPanel"
LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
</telerik:AjaxSetting>
Let us know if this makes any difference.
Best wishes,
Maria Ilieva
