ToolTip on TreeNode

I think I have done this before I just don't remember how. I tried ToolTipExtender.SetToolTip(node, tip) but it fails because the node isn't a control.

Anyone know how to do this?

Does that help?

Code:

---

    private int oldNodeIndex = -1;

    private ToolTip toolTip1;

    private void Form1_Load(object sender, System.EventArgs e)

    {

          this.toolTip1 = new System.Windows.Forms.ToolTip();

          this.toolTip1.InitialDelay = 300; //half a second delay

          this.toolTip1.ReshowDelay = 0;

    }


    private void treeView1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)

    {

          TreeNode tn = this.treeView1.GetNodeAt(e.X, e.Y);

          if(tn != null)

          {

              int currentNodeIndex = tn.Index;

              if(currentNodeIndex != oldNodeIndex)

              {

                    oldNodeIndex = currentNodeIndex;

                    if(this.toolTip1 != null && this.toolTip1.Active)

                        this.toolTip1.Active = false; //turn it off

                    this.toolTip1.SetToolTip(this.treeView1, string.Format("tooltip: node {0}", oldNodeIndex));

                    this.toolTip1.Active = true; //make it active so it can show

              }

          }

    }

Yeah, I get the idea behind this I was just hoping not to have to go that far.

Thanks though that looks like it will do the trick. I just wonder why a node isn't a control. I supose it's because it depends on the TreeView.

Thanks
