Devexpress GridView 数据格式化显示

 gridView1.CustomColumnDisplayText += gridView1_CustomColumnDisplayText;
 void gridView1_CustomColumnDisplayText(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDisplayTextEventArgs e)
        {
            if (e.Column.FieldName == "State")
            {
                switch (e.DisplayText)
                {
                    case "":
                        e.DisplayText = "有效";
                        break;
                    case "":
                        e.DisplayText = "无效";

                        break;
                }
            }
        }

    void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
        {
            var currentView = sender as GridView;
            if (currentView != null && e.RowHandle == currentView.FocusedRowHandle) return;
            Rectangle r = e.Bounds;
            if (e.Column.FieldName == "F_State")
            {
                if (e.CellValue.ToString().Equals("False"))
                {
                    e.Appearance.ForeColor=Color.Red;
                    e.Appearance.DrawString(e.Cache,e.DisplayText,r);
                    e.Handled = true;
                }
            }
        }

或者以下面的这种形式也可以的、

   
  还有一个就是改变行的颜色
  在对GridControl绑定好数据后:
  No.1:右键GridControl选择Run Designer;
  No.2:Appearance下Style Conditions点击Add,需要注意的是每一个变色条件都得Add一个变色方案;
  No.3:在Properties中需要用到的属性依次往下详解为:
  a)Appearance下BackColor=255.255.128,BackColor2=255.255.128,此项指定符合特定条件时单元格/行背景颜色,如果两项设置颜色不同时则为渐变效果;

  

  要是每次都这样设置也太不方便了。。所以我又封装了一个方法

        public void SetColumnFormatCell(object value1, object value2,Color backColor1,Color backColor2,GridColumn gridColumn,FormatConditionEnum formatType,GridView gridView)
        {
            var styleFormatCondition1 = new StyleFormatCondition();
            styleFormatCondition1.Appearance.BackColor = backColor1;
            styleFormatCondition1.Appearance.BackColor2 =backColor2;
            styleFormatCondition1.Appearance.Options.UseBackColor = true;
            styleFormatCondition1.Column = gridColumn;
            styleFormatCondition1.Condition = formatType;
            styleFormatCondition1.Expression = "true";
            styleFormatCondition1.Value1 = value1;
            styleFormatCondition1.Value2 = value2;
            gridView.FormatConditions.Add(styleFormatCondition1);
        }

调用：

  var dev=new DataGridControlHelper();
      dev.SetColumnFormatCell("无效","无效",Color.Red,Color.Red,gridColumn03,FormatConditionEnum.Equal,gridView1);
        

 虽然效果是出来了。但是我觉得效率很差。
    要是有那位网友有更好的方案。请分享一下。谢谢
