When I add a Group using RadFilter, even when I select another operator (such as 'Or', 'Not And' or 'Not Or'), the provider Result always shows 'And'. I have verified that the ExpressionItem is a GroupExpression, and its GroupOperator is 'Or' when that is selected. I can live with the display being in error, but I can't seem to access the GroupOperator = so that I can use it if that's the case. Please advise- is this a bug? Any actions or code to correct or at least access the values in the collection? I have attached a screen shot showing the issue.
