基于 DevExpress PivotGridControl 9.1 中行的数据值的自定义绘图

我正在尝试在版本 9.1 中的 PivotGridControl 的行标题中进行一些自定义绘图。在版本 8.2 中，我可以在自定义绘制事件的 FieldCellViewInfo 属性上使用 CreateDrillDownDataSource。在9.1中这个方法不存在。

我在 8.2 中使用的代码如下所示。从 CustomDrawFieldValue 事件处理程序调用。

PropertyInfo propertyInfo = typeof(PivotCustomDrawFieldValueEventArgs).GetProperty("FieldCellViewInfo",  BindingFlags.NonPublic | BindingFlags.Instance);
var fieldCellViewInfo = (PivotFieldsAreaCellViewInfo) propertyInfo.GetValue(args, null);
foreach (PivotDrillDownDataRow dataRow in fieldCellViewInfo.CreateDrillDownDataSource())
{
    if (pivotGrid.DataViewInfo.ListSource.Count > dataRow.ListSourceRowIndex)
    {
        yield return (T) pivotGrid.DataViewInfo.ListSource[dataRow.ListSourceRowIndex];
    }
}

最终用途是在已修改数据的每个行标题上的网格上添加行修改标记。我希望 9.1 能够有一种方法来做到这一点，而不需要像我们在 8.2 中那样使用私有 API 调用

I am trying to do some custom drawing in the row headers in a PivotGridControl in version 9.1. In version 8.2 I could use CreateDrillDownDataSource on the FieldCellViewInfo property on the event for the custom draw. In 9.1 this method does not exist.

The code I was using in 8.2 looks like this. Called from the CustomDrawFieldValue event handler.

PropertyInfo propertyInfo = typeof(PivotCustomDrawFieldValueEventArgs).GetProperty("FieldCellViewInfo",  BindingFlags.NonPublic | BindingFlags.Instance);
var fieldCellViewInfo = (PivotFieldsAreaCellViewInfo) propertyInfo.GetValue(args, null);
foreach (PivotDrillDownDataRow dataRow in fieldCellViewInfo.CreateDrillDownDataSource())
{
    if (pivotGrid.DataViewInfo.ListSource.Count > dataRow.ListSourceRowIndex)
    {
        yield return (T) pivotGrid.DataViewInfo.ListSource[dataRow.ListSourceRowIndex];
    }
}

What this ends up being used for is a Row modified marker on the grid on each row header that has modified data. I was hoping 9.1 would have a way of doing this without needing to use private API calls as we are doing in 8.2
