public interface IDrillDown2 : IDrillDown
Developers set a reference to an IDrillDown implementation on any or all DrillElement objects added to the Infragistics.UltraChart.Resources.Appearance.DrillDownAppearance.DrillElements property of DrillDownAppearance. This reference gets called after the user clicks on a chart element in the parent chart to drill down, and immediately before the child chart (corresponding to that DrillElement) becomes the renders on the control. Some behavior that might be necessary in the IDrillDown callback implementation a developer is expected to provide to respond to these notifications includes changing the appearance of axis labels (for a different child chart type than that of the parent), changing the chart's title, and/or altering other application-dependent logic based on the currently displayed chart.
While the same IDrillDown implementation can be provided to handle all chart drill downs, it is recommended that one IDrillDown implementation be created for each child chart. This permits any data element rendered in the chart to be distinguishable by the IDrillDown implementation (in the supplied row and column arguments to the Drill() method).
