C# code
    public class Form1 : Form    {        public Form1()        {            InitializeComponent();            //自已绘制            this.treeView1.DrawMode = TreeViewDrawMode.OwnerDrawText;            this.treeView1.DrawNode+=new DrawTreeNodeEventHandler(treeView1_DrawNode);        }        //在绘制节点事件中,按自已想的绘制        private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e)        {            if ((e.State & TreeNodeStates.Selected) != 0)            {                //演示为绿底白字                e.Graphics.FillRectangle(Brushes.Green,e.Node.Bounds);                Font nodeFont = e.Node.NodeFont;                if (nodeFont == null) nodeFont = ((TreeView)sender).Font;                 e.Graphics.DrawString(e.Node.Text, nodeFont, Brushes.White,                    Rectangle.Inflate(e.Bounds, 2, 0));            }            else            {                e.DrawDefault = true;            }            if ((e.State & TreeNodeStates.Focused) != 0)            {                using (Pen focusPen = new Pen(Color.Black))                {                    focusPen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot;                    Rectangle focusBounds = e.Node.Bounds ;                    focusBounds.Size = new Size(focusBounds.Width - 1,                    focusBounds.Height - 1);                    e.Graphics.DrawRectangle(focusPen, focusBounds);                }            }        }    }

给你个遮盖的方法把


private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
TreeView _TreeView = (TreeView)sender;
Control _SetLabel = _TreeView.Controls["SelectLab"];
if (_SetLabel == null)
{
Label _Label = new Label();
_Label.Name = "SelectLab";
_Label.AutoSize = false;
_Label.BackColor = Color.Yellow;
_Label.ForeColor = Color.Red;
_Label.Font = _TreeView.Font;
_TreeView.Controls.Add(_Label);
_SetLabel = _Label;
}
_SetLabel.Size = new Size(e.Node.Bounds.Width + 5, e.Node.Bounds.Height);
_SetLabel.Location = new Point(e.Node.Bounds.X, e.Node.Bounds.Y);
_SetLabel.Text = e.Node.Text;
}
