Property Value

true if the tree node is visible or partially visible; otherwise, false.

The following code example brings the last child tree node of the last root tree node into view in the tree view when a button is clicked. This example requires that you have a TreeView control on a Form that contains a collection of TreeNode objects, and a Button. There should be enough tree nodes so they are not all visible in the tree view control.

private void button3_Click(object sender, System.EventArgs e)
   TreeNode lastNode = treeView1.Nodes[treeView1.Nodes.Count - 1].
     Nodes[treeView1.Nodes[treeView1.Nodes.Count - 1].Nodes.Count - 1];

   if (!lastNode.IsVisible)
      MessageBox.Show(lastNode.Text + " tree node is visible.");

private void button3_Click(Object sender, System.EventArgs e)
    TreeNode lastNode = treeView1.get_Nodes().get_Item(
        (treeView1.get_Nodes().get_Count() - 1)).get_Nodes().
        get_Count() - 1).get_Nodes().get_Count() - 1));

    if (!(lastNode.get_IsVisible())) {
        MessageBox.Show(lastNode.get_Text() + " tree node is visible.");
} //button3_Click
