I'm working with a large treeview in Visual Studio 2010/Visual Basic.  I'd like to change the whole color of one specific node and everything under the node.  Is there a way I can do this other then adding a line for each child in the node and changing it's forecolor?  Here is an example of one of my nodes.

    TreeView1.Nodes.Add("SAMPLE")  
    TreeView1.Nodes(10).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLESAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(0).Tag = 68
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(1).Tag = 69
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(2).Tag = 56
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(3).Tag = 70
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(4).Tag = 71
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(5).Tag = 72
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(6).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(6).Nodes(0).Tag = 73
    TreeView1.Nodes(10).Nodes(0).Nodes(6).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(6).Nodes(1).Tag = 74
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes(0).Tag = 75
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes(1).Tag = 76
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes(2).Tag = 77
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(7).Nodes(3).Tag = 78
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(8).Tag = 79
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(9).Tag = 80
    TreeView1.Nodes(10).Nodes(0).Nodes.Add(New TreeNode("SAMPLE"))
    TreeView1.Nodes(10).Nodes(0).Nodes(10).Tag = 81

Is there a way I can get at node 10 and set every ForeColor under it in one line of code?

Thanks.

ColorNodes(TreeView1.Nodes(10))

    Private Sub ColorNodes(n As TreeNode)
        n.ForeColor = Color.Red
        For Each subNode In n.Nodes
            ColorNodes(subNode)
        Next
    End Sub
