Hi

The following little example should illustrate my problem.

I have three classes in my system:

1. Class Person
  - Name
  - Age.

2. Class Student : Person (Inherites from Person)
  - Grade

3. Class Teacher : Person (Inherites from Person)
  - Wage level

My system holds a complete list of Teachers and students like

  ObservableCollection<Person>

I have different kinds of GUI controls (listview and radCarousel sofar) that binds to this collection. If I use the radFilterData component in source mode then I see only Name and Age in the field selector. I want to be able to see Name, Age, Grade, Wage level eventhough some of them only makes sence according a specific person type. I use ItemProperties and non source mode to archieve that.

My problem is that I am a little bit confused how to do the rest. I have seen the Domain examples but doesn't guite get it. I assume I have to handle this event:

  radDataFilter.FilterDescriptors.CollectionChanged += this.OnRadDataFilterDescriptorsChanged;

But how should I do that. I should also say that I have already implemented sorting and grouping using the

  CollectionViewSource.GetDefaultView

Hopefully I will be able to have sorting, grouping and filtering working side by side. 

Property: Content

public object Content

{

get { return (object)GetValue(ContentProperty); }

set { SetValue(ContentProperty, value); }

}

public static readonly DependencyProperty ContentProperty =

DependencyProperty.Register(

"Content", typeof(object), typeof(MyOutlookBarItem),

new FrameworkPropertyMetadata

as MyOutlookBarItem).UpdateContent((object)e.NewValue);

}

});

private void UpdateContent(object sel)

{

OutlookBarItem.Content = sel;

}

grdRow = (GridViewRow)grdCell.ParentRow;

RadGridView

childGrid = grdRow.ChildrenOfType<RadGridView>().FirstOrDefault();


Please let me know

Thanks
