Treenode text different colored words

问题

I have a TreeView and each of it's Node.Text has two words. The first and second words should have different colors. I'm already changing the color of the text with the DrawMode properties and the DrawNode event but I can't figure out how to split the Node.Text in two different colors. Someone pointed out I could use TextRenderer.MeasureText but I have no idead how/where to use it.

Someone has an idea ?

Code :

formload()
{
  treeView1.DrawMode = TreeViewDrawMode.OwnerDrawText;
}

private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e) 
{
Color nodeColor = Color.Red;
if ((e.State & TreeNodeStates.Selected) != 0)
  nodeColor = SystemColors.HighlightText;

 TextRenderer.DrawText(e.Graphics,
                    e.Node.Text,
                    e.Node.NodeFont,
                    e.Bounds,
                    nodeColor,
                    Color.Empty,
                    TextFormatFlags.VerticalCenter);
}

Try this:

    private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e)
    {
        string[] texts = e.Node.Text.Split();
        using (Font font = new Font(this.Font, FontStyle.Regular))
        {
            using (Brush brush = new SolidBrush(Color.Red))
            {
                e.Graphics.DrawString(texts[0], font, brush, e.Bounds.Left, e.Bounds.Top);
            }

            using (Brush brush = new SolidBrush(Color.Blue))
            {
                SizeF s = e.Graphics.MeasureString(texts[0], font);
                e.Graphics.DrawString(texts[1], font, brush, e.Bounds.Left + (int)s.Width, e.Bounds.Top);
            }
        }
    }

You must manage State of node to do appropriated actions.

UPDATE

Sorry, my mistake see updated version. There is no necessary to measure space size because it already contains in texts[0].
