[XtraGrid] 得到列標題行的高度

代碼如下：

using System.Reflection;
using DevExpress.XtraGrid;
using DevExpress.XtraGrid.Columns;
using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraGrid.Views.Grid.ViewInfo;
using DevExpress.Utils;

           得到列標題行的高度#region 得到列標題行的高度
            PropertyInfo pi = typeof(GridView).GetProperty("ViewInfo", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.DeclaredOnly);
            GridViewInfo viewInfo = pi.GetValue(gridControl1.MainView as GridView, null) as GridViewInfo;
            int columnPanelRowHeight = viewInfo.ViewRects.ColumnPanel.Height;
            #endregion

通過viewInfo可以調用CalcRowHeight(), CalcTotalRowHeight(), CalcColumnBestWidth(), CalcRowPreviewHeight()等一系列高度寬度計算方法
通過viewInfo.ViewRects還可以得到Client, GroupPanel, Footer, Rows的矩形框數據以及IndicatorWidth, RowsTotalHeight, ColumnTotalWidth等數據
