Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public TreeNode Parent { get; }
/** @property */
public TreeNode get_Parent ()

public function get Parent () : TreeNode

Not applicable.

Property Value

A TreeNode that represents the parent of the current tree node.

If the tree node is at the root level, the Parent property returns a null reference (Nothing in Visual Basic).

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.

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.";
   }
}

private void treeView1_AfterSelect(Object sender, TreeViewEventArgs e)
{
    /* Display the Text and Index of the 
       selected tree node's Parent. 
     */
    if (e.get_Node().get_Parent() != null && e.get_Node().get_Parent().
        GetType().Equals(TreeNode.class.ToType())) {
        statusBar1.set_Text("Parent: " + e.get_Node().get_Parent().
            get_Text() + "\n" + "Index Position: " + System.Convert.
            ToString(e.get_Node().get_Parent().get_Index()));
    }
    else {
        statusBar1.set_Text("No parent node.");
    }
} //treeView1_AfterSelect
