TcxGridChartController.DataDrillDown(Integer) Method

Performs a drill-down on the specified category value of the active data group.

Declaration

function DataDrillDown(AValueIndex: Integer): Boolean; virtual;

Parameters

Name	Type
AValueIndex	Integer

Returns

Type
Boolean

Remarks

The AValueIndex parameter references the category value by its index in the active data group’s Values collection. This function returns True when a drill-down was successful; otherwise, False.

Alternatively, you can assign a category value to the active data group’s ActiveValue property to perform a drill-down on this value.

Note

A drill-down cannot be performed on the default categories which represent the highest level of detail.

Users are able to drill down data using the data level navigator. To determine whether an end-user is able to drill down on a particular category value, call the IsDataDrillDownPossible function.

To perform a drill-up, call the DataDrillUp function.
