Compiler Error Message: BC30560: 'ChartClickEventArgs' is ambiguous in the namespace 'Telerik.Charting'.
I keep getting the above error after upgrade from 2008_3_1016_dev to 2008_3_1125.
It fixed by itself after I click on "Save" a few times in MS visual Studio but error came back again when I made any changes on the page.
What do I need to do to fix this?
