Attributes

Examples

The following code example displays the Text and Index property values of the TreeNode represented by the Parent property of the TreeView.SelectedNode. This example requires that you have a Form with a TreeView control on it. The TreeView should have at least two root nodes, each having at least one child node.

C#
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{  
   /* Display the Text and Index of the 
    * selected tree node's Parent. */
   if(e.Node.Parent!= null && 
     e.Node.Parent.GetType() == typeof(TreeNode) )
   {
      statusBar1.Text = "Parent: " + e.Node.Parent.Text + "\n"
         + "Index Position: " + e.Node.Parent.Index.ToString();
   }
   else
   {
      statusBar1.Text = "No parent node.";
   }
}

Remarks

If the tree node is at the root level, the Parent property returns null.
