wpf - 我如何知道 Crystal Reports 已完成呈现？

Question

我有一个 Crystal Reports 13 wpf 控件，我正在加载来自数据集的报表和数据:

ReportDocument report = new ReportDocument();
if (report != null)
{
  report.Load(ReportFileName);
  report.SetDataSource(DataSet);
  reportViewer.ViewerCore.ReportSource = report;
}

为了知道控件何时完成渲染，我可以处理什么事件？查看器导出:

public event PageMouseEventHandler ClickPage;
public event PageMouseEventHandler DoubleClickPage;
public event DrillEventHandler Drill;
public event DrillSubreportEventHandler DrillDownSubreport;
public event NavigateEventHandler Navigate;
public event RefreshEventHandler Refresh;
public event SearchEventHandler Search;
public event RoutedEventHandler SelectionChange;
public event RoutedEventHandler ViewChange;
public event ZoomEventHandler ViewZoom;

ViewerCore 仅导出:

public event ExceptionEventHandler Error;

这些似乎都不合理。我也曾短暂地使用过 ReportClientDocument。

为了后代:

DependencyPropertyDescriptor p = DependencyPropertyDescriptor.FromProperty(SAPBusinessObjects.WPF.Viewer.ViewerCore.TotalPageNumberProperty, typeof(SAPBusinessObjects.WPF.Viewer.ViewerCore));
p.AddValueChanged(reportViewer.ViewerCore, OnPageCountChanged);

由于 TotalPageNumber 属性在该页面呈现后正确更新...

private void OnPageCountChanged(object sender, EventArgs e)
{
   //do whats needed
}

您知道控件何时完成呈现。
