I am getting the following message in a user control I have created:
Script control 'rrLocationRationg' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescription().
Parameter name: scriptControl

I have the following code working, however if I uncomment the code in RadCBLocations_ItemsRequested I get the above error. I need to be able to do this as the data pulled back is to large unless there is some type of filtering done. Any suggestion would be greatley appreciated.
