Hi!
How to add tooltip to a TreeView node?
Here is one way that you could do:
Fill out the tag property for the treenodes and on mousemove event, update
the tooltip control with the tag property of the current node.
private void Form1_Load(obje ct sender, System.EventArg s e)
{
TreeNode rootNode = this.treeView1. Nodes [0];
rootNode.Tag="T his is the node 0";
rootNode.Nodes[0].Tag="this is node 1";
rootNode.Nodes[0].Nodes[0].Tag="this is node 2";
}
private void treeView1_Mouse Move(object sender,
System.Windows. Forms.MouseEven tArgs e)
{
TreeNode currentNode = this.treeView1. GetNodeAt(e.X,e .Y);
if (null != currentNode)
{
if (currentNode.Ta g.ToString() !=
this.toolTip1.G etToolTip(this. treeView1).ToSt ring())
{
this.toolTip1.S etToolTip(this. treeView1,curre ntNode.Tag.ToSt ring());
}
}
else
{
this.toolTip1.S etToolTip(this. treeView1,"");
}
}
Hope this helps.
