   int column,
   ChartType chartType,
   object dataSource
)

Parameters

row

DataRow index underlying the parent chart element the end user has drilled down into.

column

DataColumn index underlying the parent chart element the end user has drilled down into.

chartType

The future chart type (after the Drill callback returns.)

dataSource

The future data source (bound to the future chart type after Drill callback returns.)

Remarks

This is a callback method from within the control's drill down processing that gives developers the opportunity to modify a chart's appearance and presentation when end users drill down into previously prepared drillable chart elements (see the DrillElement class for more information on defining the drill down hierarchy).
