DEV GridControl 根据单元格值改变背景色

 GridControl 根据单元格值改变背景色(需要用到CustomDrawCell事件)

方法1:

 private void gdvClient_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
        {
            if (e.Column.FieldName == "VerifyCN") //指定列
            {
                if ((string)e.CellValue == "未确认")  //条件  e.CellValue 为object类型
                    e.Appearance.BackColor = Color.Red;
            }                
        }

方法2:

 private void gdvStatistics_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
        {
            DevExpress.Utils.AppearanceDefault appRed = new DevExpress.Utils.AppearanceDefault
                (Color.Black, Color.Red, Color.Empty, Color.Red, System.Drawing.Drawing2D.LinearGradientMode.Horizontal);
            DevExpress.Utils.AppearanceDefault appYellow = new DevExpress.Utils.AppearanceDefault
                (Color.Black, Color.Yellow, Color.Empty, Color.Yellow, System.Drawing.Drawing2D.LinearGradientMode.Horizontal);
            DevExpress.Utils.AppearanceDefault appGreen = new DevExpress.Utils.AppearanceDefault
                (Color.Black, Color.Green, Color.Empty, Color.Green, System.Drawing.Drawing2D.LinearGradientMode.Horizontal);
            if (e.Column.FieldName == "Difference")//指定列
            {
                string strTemp = gdvStatistics.GetRowCellDisplayText(e.RowHandle, "Difference").ToString().Trim();
                if (Convert.ToInt32(strTemp) > 0)
                    DevExpress.Utils.AppearanceHelper.Apply(e.Appearance, appRed);
                else if (Convert.ToInt32(strTemp) == 0)
                    DevExpress.Utils.AppearanceHelper.Apply(e.Appearance, appGreen);
                else
                    DevExpress.Utils.AppearanceHelper.Apply(e.Appearance, appYellow);
            }
        }
