کار بسیار ساده ای هست امیدوارم که جواب سوال شما همین باشه

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{

messagebox.show("پیغام شما");


}

اینم یه نمونه با if


private void treeViewRightMenu_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Up)
{
btnBottomPanelHeader.Text = treeViewRightMenu.SelectedNode.PrevNode.Text;
}
if (e.KeyCode == Keys.Down)
{
btnBottomPanelHeader.Text = treeViewRightMenu.SelectedNode.NextNode.Text;
}
}
