Hello,
This FilterDescriptors collection can contain CompositeFilterDescriptor or FilterDescriptor instances. The CompositeFilterDescriptor contains other descriptors and combines them with a logical operator of OR or AND. The simple FilterDescriptor class is a leaf of the tree and contains a Member, Operator, Value, MemberType.
I am afraid there is not a way to compare between two members.

I'm developing a workaround to implement this feature.
Basically, I created my own EditorTemplate where the user can choose to insert a static value or select an item from a Combobox which is populated with che Member of my object.
The only problem that I found is that I have to cast each member from my datasource to a string member. Because if I create a filter on a Integer member the value can't be a string (in my situation the value would be the member name, which is a string). But this solution isn't perfect because if all the Member are string I can't use every comparision operator, but only the ones that work with the string type. What can you suggest to me? Are there any way to avoid this limitation?

Hello,
Basically you can check the Create Custom Filter Editors article. If this is not what you need, may I ask you to open a new support ticket and send me a demo project illustrating your attempt?
