.NET Framework 4

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

Copy 
public string ToolTipText { get; set; }

Property Value

Type: System.String
Gets the text that appears when the mouse pointer hovers over a TreeNode.

You must set the ShowNodeToolTips property of the parent TreeView to true for the ToolTipText to be visible at run time.

If the TreeView control has a ToolTip and also contains a TreeNode that has a ToolTip, only the ToolTip for the node will be shown.

The following code example demonstrates how to use the ToolTipText and ShowNodeToolTips properties. To run this example, paste the following code into a Windows Form and call InitializeTreeViewWithToolTips from the form's constructor or Load event handler.

C#
VB
Copy 

TreeView treeViewWithToolTips;
private void InitializeTreeViewWithToolTips()
{
    treeViewWithToolTips = new TreeView();
    TreeNode node1 = new TreeNode("Node1");
    node1.ToolTipText = "Help for Node1";
    TreeNode node2 = new TreeNode("Node2");
    node2.ToolTipText = "A Tip for Node2";
    treeViewWithToolTips.Nodes.AddRange(new TreeNode[] { node1, node2 });
    treeViewWithToolTips.ShowNodeToolTips = true;
    this.Controls.Add(treeViewWithToolTips);

}
