How to set DataTemplate of HierarchyChildTemplate (Code)

[Jerome]

Hello,

I was trying to build up the DataTemplate for the HierarchyChildTemplate in my code.

As example the one from the online documentation http://www.telerik.com/help/wpf/gridview-how-to-access-child-gridview.html

<telerik:RadGridView Name="gridView" ItemsSource="{Binding Person}">
<telerik:RadGridView.ChildTableDefinitions>
<telerik:GridViewTableDefinition />
</telerik:RadGridView.ChildTableDefinitions>
<telerik:RadGridView.HierarchyChildTemplate>
<DataTemplate>
<telerik:RadGridView ItemsSource="{Binding Children}" Name="childGrid" ShowGroupPanel="False" />
</DataTemplate>
</telerik:RadGridView.HierarchyChildTemplate>
</telerik:RadGridView>

I tried something like:

gridView.HierarchyChildTemplate =
                new DataTemplate(
                        new RadGridView
                        {
                            ShowGroupPanel = false,
                            IsReadOnly = true,
                            ItemsSource = new Binding("Children")
                        });

But i set the dataType in that constructor and not same property like in the xaml. What's the property i need to set?

Thanks.

Hello,

This is not the correct syntax for creating the DataTemplate in code behiond. I would suggest you to declare it in XAML and then set it in code instead. 
For example:

this.gridView.TableDefinition.ChildTableDefinitions.Add(new GridViewTableDefinition());
this.gridView.HierarchyChildTemplate = this.FindResource("hierachyDataTemplate1") as DataTemplate;

Can you apply this?

I was able to solve it with subscribing to the DataLoading event and use the GridViewDataControl instead of a second RadGridView.
