Question

I make windows form application. I have on form TreeView, I add few nodes and add ContextMenuStrip.

  var menu = new ContextMenuStrip();
  menu.Items.Add("Some text", new Bitmap(1, 1), new EventHandler(function_name));

  var treeView = new TreeView(..);
  treeView.ContextMenuStrip = menu;      

  treeView.Nodes.Add(new TreeNode()
  {
         ...
         Tag = someObject

Answer 1

You can handle the TreeNodeMouseClick event. In your TreeNodeMouseClickEventHandler you will have access to a TreeNodeMouseClickEventArgs argument. This argument contains a number of properties you can use to check which mouse button was clicked on which node. For example.

private TreeNode rightClickeNode;

void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        rightClickedNode = e.Node;
    }
}

You can then access rightClickedNode from your function_name.
