Question

我想简要解释一下我的情况，我使用DashboardViwer项目，并将xml加载到由DashboardDesigner创建和保存的onload上。

然后，我填写DashboardObjectDataSource并将其添加到仪表板数据源以将其设置为项目。

最后，我在仪表板查看器中为PivotGridControl打开了一些属性和activere customizationform。

我根据我的设计正确地看到了报告结果，该设计是由仪表板设计师创建的。

但是，当我想要更改字段顺序或地点时，我会得到这种例外情况;

   position: DevExpress.XtraPivotGrid.Data.PivotFieldCellValueItem.GetTextCore()
   position: DevExpress.XtraPivotGrid.Data.PivotFieldValueItem.GetCustomText(Boolean calculateIsCustomDisplayText)
   position: DevExpress.XtraPivotGrid.Data.PivotFieldValueItem.CalculateText()
   position: DevExpress.XtraPivotGrid.Data.PivotFieldValueItem.get_Text()
   position: DevExpress.XtraPivotGrid.Data.PivotFieldValueItem.get_DisplayText()
   position: DevExpress.XtraPivotGrid.ViewInfo.PivotFieldsAreaCellViewInfo.get_DisplayText()
   position: DevExpress.XtraPivotGrid.ViewInfo.PivotFieldsAreaCellViewInfoBase.CreateHeaderInfoArgs(GraphicsCache graphicsCache)
   position: DevExpress.XtraPivotGrid.ViewInfo.PivotFieldsAreaCellViewInfoBase.InternalPaint(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfo.Paint(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfoCollection.Paint(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfo.PaintChildren(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfo.Paint(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfoCollection.Paint(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfo.PaintChildren(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfo.Paint(ViewInfoPaintArgs e)
   position: DevExpress.XtraPivotGrid.ViewInfo.BaseViewInfoControl.OnPaint(PaintEventArgs e)
   position: DevExpress.XtraPivotGrid.PivotGridControl.OnPaint(PaintEventArgs e)
   position: System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer)
   position: System.Windows.Forms.Control.WmPaint(Message& m)
   position: System.Windows.Forms.Control.WndProc(Message& m)
   position: DevExpress.XtraPivotGrid.PivotGridControl.WndProc(Message& m)
   position: System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   position: System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)

在当前版本中，Dashboard Pivot Grid Item不支持   自定义表单功能。因此，如果您显示它   手动使用内部透视网格控件的API，自定义   表单可能无法正常工作，或者会在您的表单中引发异常   情况下。

目前，可以在Pivot中重新排序维度和度量   使用仪表板设计器的网格项。如果这种方法不符合   您的要求，请您更好地描述您的情景   详情？我们期待着您的回复。

DashboardViewer控件仅用于显示仪表板。那是   为什么会这样   没有简单的方法来使用PivotGrid控件的自定义   DashboardViewer中的功能。要自定义仪表板   要求的方式，您需要使用DashboardDesigner控件。
