There are couple things you can do, example, there is treeView object, called "mytreeView",

1. private void mytreeView_MouseDoubleClick(object sender, MouseEventArgs e)
{
//
// Get the selected node.
//
TreeNode node = treeView1.SelectedNode;
.....

2. private void mytreeView_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
if (e.Action == TreeViewAction.ByMouse)
.....
