I have a TreeView
which uses a HierarchicalDataTemplate
to bind its data.
It looks like this:
<TreeView x:Name="mainTreeList" ItemsSource="{Binding MyCollection}>
<TreeView.Resources>
<HierarchicalDataTemplate
DataType="{x:Type local:MyTreeViewItemViewModel}"
ItemsSource="{Binding Children}">
<!-- code code code -->
</HierarchicalDataTemplate>
</TreeView.Resources>
</TreeView>
Now, from the code-behind of say the main window, I want to get the current selected TreeViewItem
. However, if I use:
this.mainTreeList.SelectedItem;
The selectedItem is of type MyTreeViewItemViewModel
. But I want to get the 'parent' or 'bound' TreeViewItem
. I do not pass that to my TreeViewItemModel
object (wouldn't even know how).
How can I do this?
