TreeNode mouse hover tooltip not showing up

c#, mousehover, treeview, winforms

Solution

looks like the problem is in the

TreeNode selNode = (TreeNode)treeView1.GetNodeAt(Cursor.Position);

line, change it to

TreeNode selNode = (TreeNode)treeView1.GetNodeAt(treeView1.PointToClient(Cursor.Position));

and it should work; I would also recomd to look at the following article: How to add a ToolTip to a TreeNode in Visual C# for detalis on how to add tooltips to the treeview

hope this helps, regards

Problem

I am trying to show a tooltip when mouse hovers on a treeview node. But the tooltip is not showing up. This is my code: ``` private void treeView1_MouseHover(object sender, EventArgs e) { toolTip1.RemoveAll(); TreeNode selNode = (TreeNode)treeView1.GetNodeAt(Cursor.Position); if (selNode != null) { if (selNode.Tag != null) { Product selProduct = selNode.Tag as Product; if (selProduct != null) { toolTip1.SetToolTip(treeView1, selProduct.ProductName + "\n" + selProduct.ProductCategory.ToString()); } } } } ``` What should I check for?
