The ID property is a DrillDownID object that identifies the data row and column underlying a given chart element that will be drillable. During drill down processing, a DrillElements is located based on its matching a DrillDownID in the currently displayed parent chart. Failing to properly initialize a DrillElement's ID is the most likely cause of a chart element not behaving as if it were drillable at run-time.
