Windows Forms

I have a tree created at design time with 3 root nodes and 3 levels 3x3x3 =39 nodes as the default.

The nodes can be dynamically recreated.

When I cleared the nodes then recreated them, I tried looping through to add properties to the nodes of each level including their relevant context menu name.

<pre lang="text">
	Private Sub RedoTree_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RedoTree.Click

		treeLoad()
		treeExecutive.ExpandAll()
		restoreTP()
		treeExecutive.Nodes(0).EnsureVisible()

	End Sub
<pre>
	Sub restoreTP() '				renew treenode properties

		Dim s As String, l As Short

		treeExecutive.Update()

		For Each treenode In treeExecutive.Nodes
			s = treenode.Name
			l = Len(s)
			treenode.ForeColor = Color.GhostWhite

			If treenode.Text <> s Then treenode.ForeColor = Color.Black

			Select Case l
				Case 1
					treenode.NodeFont = New Font("Arial Rounded MT Bold", 10.8)
					treenode.ContextMenuStrip = CMSRoot
				Case 2
					treenode.NodeFont = New Font("Arial", 10.2)
					treenode.ContextMenuStrip = CMSTree
				Case Else
					treenode.NodeFont = New Font("Arial Narrow", 9)
					treenode.ContextMenuStrip = CMSTree
			End Select

		Next

	End Sub
