Right click on TreeView: Get the node clicked at


There is a TreeView control with n number of nodes. When the user right clicks on the TreeView control, get the node on which the right click was performed.


In TreeView control, SelectedNode property is set whenever left click occurs. This is not true for right clicks. So, we need to have some workaround for this.

Solution 1:

The most popular solution is to handle the MouseDown event. Check if the click was a right click and then use the TreeView control’s GetNodeAt API to get the node which was clicked at.

private void treeView1_MouseDown(object sender, MouseEventArgs e)
if (e.Button == MouseButtons.Right)
TreeNode selectedNode = treeView1.GetNodeAt(e.X, e.Y);
MessageBox.Show("You clicked on node: " + selectedNode.Text);

Solution 2:

Handle the NodeMouseClick event. The TreeNodeMouseClickEventArgs has the node which was clicked at.

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
if (e.Button == MouseButtons.Right)
MessageBox.Show("You clicked on node: " + e.Node.Text, "Solution 2");

SelectedNode property of a treeview is set whenever a left click occurs. Why can’t the same be applied for right click? Right click on a treeview is such a common UI event, that users will benefit from it.

    Excellent explanation and solutions. I wish Microsoft would just make a NodeMouseRightClick() event but until they do, this is the next best thing.

  2. “SelectedNode property of a treeview is set whenever a left click occurs. Why can’t the same be applied for right click?”

    This would cause an inconsistency for instance when you display a context menu and the user cancels the menu.

    we simply need to handle the NodeMouseClickEvent.

    private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)


    if (e.Button == MouseButtons.Right)


    this.treeView1.SelectedNode = e.Node;

    The exemple is fine for a WPF application but it doesn’nt work for a .Net application. That TreeNodeMouseClickEventArgs e) doesn’t exist.
