Add\Edit\Remove Right Click Context Menu Of WPF TreeView Code Behind

Question

Answer 1

Why you need that? Perhaps it would be better to do it in an other way without affecting a code behind? I preffer when View and logic is decoupled, basically this is MVVM approach I would suggest to follow.

Anyway you can do it by adding Initialized event handler and than handing it in code behind:

XAML:

<TreeView ... />
  <TreeView.ContextMenu Initialized="OnTreeViewMenuInitialized">
    <MenuItem Header="Add" Command="{Binding AddCommand}" />
  </TreeView.ContextMenu>
</TreeView>

Code behind:

private void OnTreeViewMenuInitialized(object sender, EventArgs e)
{
     var contextMenu = (ContextMenu)sender;
     ...
}
