In my gridviewcolumns I can set a sortmemberpath and a groupmemberpath, what I'm missing is something like a FilterMemberPath.
Is it possible to implement this? This would be very helpful in a lookup value scenario.

Filtering is quite different from sorting and grouping and that is why we have chosen not to provide a property like this. Custom filtering is done by creating a custom filtering control. Inside this control you will have total control over what fields you are filtering on. They can be any, unlike with the built-in filtering control which always filters using the column's data field.
To see two such custom filtering controls in action, please check out our online demos. Look for the "Custom Filter Controls" example.
To learn how to build one of your own, please follow my step-by-step tutorial Custom Filtering with RadGridView for Silverlight. Since we are sharing the same code-base for both WPF and Silverlight, this blog post is relevant for WPF as well. Everything will be exactly the same.
I hope this helps.
