I'm using Rad Control 2013 Q1 - SP1 ( and SP2 ) in VS2010. When dragging RadFilter on aspx design, the Properties window not show any property ( Radfilter still selected). Properties window always display for other Rad controls correctly. And if I select again Radfilter from Properties window , VS2010 closed!
If I put cursor on aspx source, at child element (ex, <telerik:RadFilterTextFieldEditor>), the Properties window display properties of it correctly. And no result If I put cursor on element RadFilter.
I think there is a problem of RadFilter.
