Have you ever tried to add nodes in the Microsoft Treeview using the AddRange method, it is not fun to do that as you cannot create a new TreeNodeCollection.After doing quite a bit of research we found a way to do this.Here is the trick.
vb.net sample code:
Dim ndc as new list(of TreeNode)
For i as Integer = 0 to 10 step 1
Dim nd as new TreeNode
nd.text = "node " + i.tostring
