WPF selection of a TreeView item as context menu is called

Question

This problem relates mainly to context menus, but in my specific case it\'s about a TreeView control.

The TreeView item contains a StackPanel, and on that StackPanel

Answer 1

You could add an IsSelected property to your SceneViewModel and CharacterViewModel classes and bind the IsSelected of the TreeViewItem to these properties using a style. In the same style you could then hook up an event handler for the PreviewMouseRightButtonDown to set the source property:

---

private void treeView_PreviewMouseRightButtonDown(object sender, MouseButtonEventArgs e)
{
    TreeViewItem tvi = sender as TreeViewItem;
    CharacterViewModel cvm = tvi.DataContext as CharacterViewModel;
    if (cvm != null)
    {
        cvm.IsSelected = true;
    }
    else
    {
        SceneViewModel svm = tvi.DataContext as SceneViewModel;
        if (svm != null)
            svm.IsSelected = true;
    }
}

Make sure that the CharacterViewModel and SceneViewModel classes implement the INotifyPropertyChanged interface and raise the PropertyChanged event in the setter of the new IsSelected property.
