    I'm trying to use the RadFilter to get the expression tree so that I can use it in a Linq Where clause. 
    In WPF, I can use the DataFilter control to do this:
    Is it possible to do the same kind of thing with the RadFilter? In the ApplyExpressions event I can get the e.ExpressionRoot.Expressions property but I can't see a way to convert that to anything usable by Linq.

    In order to implement the desired functionality you could download the Dynamic LINQ library which builds a predicate LINQ tree expression from a string representation and executes it. You could download it and get more information on the topic from the link below. Note that Telerik RadControls for ASP.NET AJAX are also using the library internally.

    I have provided the same answer in the support thread that you have posted. Note that we recommend avoiding duplicate questions so we could improve our response time and quality of answers.
