Multi level Child Table Definition

[WVA WVA]

Hi all,
I want to display a multi level child table in grid view. In C# code I have something similar to:

           GridViewTableDefinition universities = new GridViewTableDefinition();
            universities.Relation = new Telerik.Windows.Data.PropertyRelation("Universities");
            RadGridView1.ChildTableDefinitions.Add(universities);

            GridViewTableDefinition careers = new GridViewTableDefinition();
            careers.Relation = new Telerik.Windows.Data.PropertyRelation("Careers");
            universities.ChildTableDefinitions.Add(careers);


            GridViewTableDefinition subjects = new GridViewTableDefinition();
            subjects.Relation = new Telerik.Windows.Data.PropertyRelation("Subjects");
            careers.ChildTableDefinitions.Add(subjects);

And in xaml file:

       <Controls:RadGridView.ChildTableDefinitions>
                <Controls:GridViewTableDefinition AutoGenerateFieldDescriptors="True">
                    <Controls:GridViewTableDefinition.Relation>
                        <data:PropertyRelation ParentPropertyName="Univesities" />
                    </Controls:GridViewTableDefinition.Relation>
                </Controls:GridViewTableDefinition>

                <Controls:GridViewTableDefinition AutoGenerateFieldDescriptors="True">
                    <Controls:GridViewTableDefinition.Relation>
                        <data:PropertyRelation ParentPropertyName="Careers" />
                    </Controls:GridViewTableDefinition.Relation>
                </Controls:GridViewTableDefinition>

                <Controls:GridViewTableDefinition AutoGenerateFieldDescriptors="True">
                    <Controls:GridViewTableDefinition.Relation>
                        <data:PropertyRelation ParentPropertyName="Subjects" />
                    </Controls:GridViewTableDefinition.Relation>
                </Controls:GridViewTableDefinition>
            </Controls:RadGridView.ChildTableDefinitions>

But this does not do what I want, I think there must be somthing similar to the following xaml to have a multilevel child table definition:

          <Controls:RadGridView.ChildTableDefinitions>
                <Controls:GridViewTableDefinition AutoGenerateFieldDescriptors="True">
                    <Controls:GridViewTableDefinition.Relation>
                        <data:PropertyRelation ParentPropertyName="Universities" />

                        <Controls:GridViewTableDefinition AutoGenerateFieldDescriptors="True">
                            <Controls:GridViewTableDefinition.Relation>
                                <data:PropertyRelation ParentPropertyName="Careers" />

                                <Controls:GridViewTableDefinition AutoGenerateFieldDescriptors="True">
                                    <Controls:GridViewTableDefinition.Relation>
                                        <data:PropertyRelation ParentPropertyName="Subjects" />
                                    </Controls:GridViewTableDefinition.Relation>
                                </Controls:GridViewTableDefinition>

                            </Controls:GridViewTableDefinition.Relation>
                        </Controls:GridViewTableDefinition>

                    </Controls:GridViewTableDefinition.Relation>
                </Controls:GridViewTableDefinition>

            </Controls:RadGridView.ChildTableDefinitions>

But of course, this does not work.
Entity classes are similar to:

public class MainClass
{
     public ObservableCollection<University> Universities{set;get;}
}

public class University
{
     public ObservableCollection<Career> Careers{set;get;}
}

public class Career
{
     public ObservableCollection<Subject> Subjects{set;get;}
}


public class Subject
{
}

I hope you can help me, thank you in advance.

Hello, to see an example of a multi level child grid view see my demo I recently posted.

http://www.telerik.com/community/forums/silverlight/gridview/q3-gridviewheaderrow-template-bug.aspx

The way this works in Q3 is slightly different to Q2, you don't need to bother with defining Child Table Definitions in code anymore, you can define this all in XAML.

Hope this helps,
James.
