如何用代码使TreeView1.SelectedNode高亮显示

先把treeview的DrawMode属性设置成OwnerDrawText

然后DrawNode事件

private void treeView1_DrawNode(object sender, DrawTreeNodeEventArgs e)

        {

            if ((e.State & TreeNodeStates.Selected) == TreeNodeStates.Selected)

            {

                e.Graphics.FillRectangle(new SolidBrush(Color.Yellow), e.Bounds); //这里设置颜色

                e.Graphics.DrawString(e.Node.Text, treeView1.Font, new SolidBrush(Color.White), e.Bounds.Location);

            }

            else

            {

                e.DrawDefault = true;

            }

 

        }
