ToolTip on TreeNode

[Magiaus]

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?

     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
