Hi,
how can a MenuItem in ContextMenu realize what object called the ContextMenu? I have databinded treeView and I want to know, which TextBlock item was right-clicked. I don't want the databinded object behind, I need work with the TextBlock. Thanks!

Hi I think this code can help u

void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
     TreeNode myNode =  treeView1.GetNodeAt(e.X, e.Y);
     if(myNode != null)
          //your code like treeView1.SelectedNode = myNode;
     else
          //your code like MessageBox.Show("No treenode selected", "Invalid selection");
}

Just remember that the if block is necessary else compiler may give a NullRefrenceException
Hope this help you

This would maybe work form Windows Forms, but I am trying to work with WPF. But thanks anyway.

Take a look through this[^] from MSDN. It is about a ContextMenu on a TreeView but I think the techniques (and there are a few of them) should work for you.

You might also take a look at the PlacementTarget[^] property of the ContextMenu.
