I have a RadPanelBar with two RadPanelBarItems. I would like to keep these two items in expanded form all the time. I’m also adding RadPanelBarItems programmatically and would like to Collapse only the new items that were added. How can I keep the first two items expanded?

Thanks

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;

}
