We are using a RadDataFilter to let the user create simple filter expressions. How can we modify the Members shown in the combobbox PART_SimpleFilterMemberComboBox?
Assume we filter on a list of employees where the employee class has three properties ID, Name and Age and we only want Name and Age to appear in the
PART_SimpleFilterMemberComboBox?

Hi,
You can achieve your goal, configuring the property you would like to not show with Browsable(false) attribute.
For example:
Let me know how this works for you.

For example:
public class YourObject: INotifyPropertyChanged{ public event PropertyChangedEventHandler PropertyChanged; private string id; [Browsable(false)] public string ID { get { return this.id; } set { if (value != this.id) { this.id= value; this.OnPropertyChanged("ID"); } } } ... }Let me know how this works for you.

Thank you Didie! [Browsable(false)] works fine for simple cases.
Meanwhile I have found myself a way to do more complex filtering: In the Initializied event of PART_SimpleFilterMemberComboBox I grab SimpleFilterViewModel.AvailableMembers which contains all browsable properties of the class I want to filter on.
Then I warp AvailableMembers into a CollectionView and set a Filter and SortDescriptions on this CollectionView.
The PART_SimpleFilterMemberComboBox.ItemsSource binds to this CollectionView.
So I can do any filtering I want and get a nicely ordered Combobox for the user to select the member he wants to filter on :)
