Telerik RAD Combobox doesn't work in DotNetNuke (DNN)

Firebug confirmed that it was properly populated, but i couldn't make it to drop down. Turns out i had "Supports Partial Rendering" option unchecked in the View control of my module. Allowing partial rendering resolved the dropdown issue.
Here's how to do it:
1. Login as HOST
2. Go to Host > Module Definitions
3. Select your cutom module from the list
4. Scroll all the way down and select your VIEW control
5. Check "Supports Partial Rendering" checkbox
6. Click "Update" link
Hope this helps
