XtraGridControl中Preview格式下中文換行問題

添加兩個事件，計算寬度

void gridView1_CustomDrawRowPreview(object sender, Views.Base.RowObjectCustomDrawEventArgs e)

        {
            e.Appearance.DrawString(e.Cache, gridView1.GetRowPreviewDisplayText(e.RowHandle), e.Bounds, StringFormat.GenericTypographic);
            e.Handled = true;
        }
        void gridView1_MeasurePreviewHeight(object sender, Views.Grid.RowHeightEventArgs e)
        {
            SizeF size = gridView1.Appearance.Preview.CalcTextSize(CreateGraphics(), StringFormat.GenericTypographic,
                gridView1.GetRowPreviewDisplayText(e.RowHandle), gridControl1.Width - 6);
            e.RowHeight = (int)size.Height;

        }

或者用layoutView形式解決此問題。
