[DevExpress]设置FocusedNode的背景色

关键代码：

        /// <summary>
        /// 设置FocusedNode的背景色
        /// 说明：
        /// 在CustomDrawNodeCell事件中使用
        /// 示例：
        /// _curTree.SetFocusedNodeBackColor(Color.Green, Color.PeachPuff, Color.Black, e);
        /// </summary>
        /// <param name="tree">TreeList</param>
        /// <param name="backColor1">起始背景颜色</param>
        /// <param name="backColor2">结束背景颜色</param>
        /// <param name="foreBrush">字体颜色</param>
        /// <param name="e">CustomDrawNodeCellEventArgs</param>
        public static void SetFocusedNodeBackColor(this TreeList tree, Color backColor1, Color backColor2, Color foreBrush, CustomDrawNodeCellEventArgs e)
        {
            if (e.Node == tree.FocusedNode)
            {
                Brush _backBrush, _foreBrush;
                _backBrush = new LinearGradientBrush(e.Bounds, backColor1, backColor2, LinearGradientMode.Horizontal);
                _foreBrush = new SolidBrush(foreBrush);
                e.Graphics.FillRectangle(_backBrush, e.Bounds);
                e.Graphics.DrawString(e.CellText, e.Appearance.Font, _foreBrush, e.Bounds, e.Appearance.GetStringFormat());
                e.Handled = true;
            }
        }

代码使用：

        private void tlLHData_CustomDrawNodeCell(object sender, CustomDrawNodeCellEventArgs e)
        {
            TreeList _curTree = sender as TreeList;
            _curTree.SetFocusedNodeBackColor(Color.Orange, Color.PeachPuff, Color.Black, e);
        }
