TreeNode.IsVisible Property

Gets a value indicating whether the tree node is visible or partially visible.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[BrowsableAttribute(false)]
public bool IsVisible { get; }

Property Value

Type: System.Boolean
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 that 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)
   {
      lastNode.EnsureVisible();
      MessageBox.Show(lastNode.Text + " tree node is visible.");
   }
}
