DashboardViewer PivotDashboardItem PivotGridControl 拖动异常

Question

我想简单解释一下我的情况， 我使用 DashboardViwer 项目并将 xml 加载到它 onload 已由 DashboardDesigner 创建和保存。

然后，我填充 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 自定义表单。

根据仪表板设计师创建的设计，我可以正确看到报告结果。

但是，当我想更改现场订单或地点时，我会遇到此异常；

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 手动使用内部枢轴网格控件的 API，自定义 表单可能无法正常工作，或者会抛出异常，如您的 案例。

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目。如果这种方法不符合 您的要求，请您更详细地描述您的场景 细节？我们期待您的来信。

DashboardViewer 控件仅用于显示仪表板。那是 为什么有 没有简单的方法来使用 PivotGrid 控件的自定义 DashboardViewer 中的功能。在 所需的方式，您将需要使用 DashboardDesigner 控件。
