Hello,

I have the following situation: I have an interface IBasicTreeItem which is used as the basic interface for all tree nodes. I also implemented two classes that implement this interface. The classes are NodeTreeItem (for non-leaf nodes) and LeafNodeTreeItem (for leaf nodes).

public interface IBasicTreeItem
    {

       ...

        IEnumerable<IBasicTreeItem> Children { get; }
    }

    public class NodeTreeItem : IBasicTreeItem
    {
        ...
    }

    public class LeafNodeTreeItem : BasicTreeItem
    {
       ...
    }

The ItemsSource of the XamDataTree binds to a colelction of IBasicTreeItem objects.

In XAML I want to have different layouts for the different types, like for example

<ig:NodeLayout Key="NodeLayout" TargetTypeName="BasicTreeItem"> 

...

 </ig:NodeLayout>

<ig:NodeLayout Key="LeafNode" TargetTypeName="LeafNodeTreeItem"> 

...

 </ig:NodeLayout>

Using the standard TreeView and DataTemplates for the above two classes, it is very easy to achieve this. But how can that be done with the XamDataTree?

Thanks a lot in advance,

Raja
