Question

How can I find out which node in a tree list the context menu has been activated? For instance right-clicking a node and selecting an option from the menu.

I can’t use the TreeViews’ SelectedNode property because the node is only been right-clicked and not selected.

You can add a mouse click event to the TreeView, then select the correct node using GetNodeAt given the mouse coordinates provided by the MouseEventArgs.

void treeView1MouseUp(object sender, MouseEventArgs e) {     if(e.Button == MouseButtons.Right)     {         // Select the clicked node         treeView1.SelectedNode = treeView1.GetNodeAt(e.X, e.Y);          if(treeView1.SelectedNode != null)         {             myContextMenuStrip.Show(treeView1, e.Location);         }     } }
