In the click event handler for the active regions i'd like access to an identifier for the bar selected but I can't find a way to set this on a databound chart. There is an itemindex but that requires a known order for the displayed items. Are there any properties that I could use for this?
I'm binding to a list of custom objects and indicating which properties to use for the bar chart using:

DurationReport.PlotArea.XAxis.DataLabelsColumn =

Hello Mary,
You can use the Name property for this. Usually, it is populated for pie charts as the legend shows an item for each pie slice and the legend items' text is taken from this property. However, it is rarely used with bars, so you can populate it with the ID. Unfortunately, there is no way to do this like it's done with the labels (DataLabelsColumn), so you will need to wire ItemDataBound event and populate it:
e.SeriesItem.Name = ((MyType)e.DataItem)["MyIDField"].ToString();
Hope this helps.
