Using Error Provider with TreeView?

Question

Can the standard error provider (icon) be used on Treeview nodes?

I have one parent node with one child, I want to show the icon next to the parent only and remove the + and - images .

Working with VB .NET, but can use a C# example. Thanks much! 

 

Answer 1

No, the TreeView does not support ErrorProvider on the individual TreeNodes.

Consider some scheme where you change the image for the TreeNode yourself and provide a tooltip, etc. on the TreeNode with the error message.

Thanks for your reply.

Ok, so here is what seems to work. I got the icon from here. I did a target save picture as... on the red provider icon.

Here is some sample code. I put the IC27018.gif in the resources folder.

 Dim TVNode As TreeNode
 TVNode = TreeView1.Nodes.Add("First Names")
 TVNode.Nodes.Add("Mike")
 TVNode.Nodes.Add("Bill")
 TVNode.Nodes.Add("John")
 TVNode.Nodes.Add("Pete")

 Dim myImageList As New ImageList()
 myImageList.Images.Add(My.Resources.IC27018)
 TreeView1.ImageList = myImageList
 TreeView1.ImageIndex = 0
 TreeView1.SelectedImageIndex = 0
 TreeView1.ExpandAll()
