PivotCellEventArgs is the data class for the following events:

• PivotGridControl.CellClick
• PivotGridControl.CellDoubleClick

Remarks

The PivotGridControl.CellClick and PivotGridControl.CellDoubleClick events occur when an end-user clicks or double-clicks a pivot grid cell, respectively. To obtain which mouse button has been clicked, use the PivotCellEventArgs.Button property.

Example

This example demonstrates how to obtain the records from the control’s underlying data source for a particular cell. Double-click a cell to invoke a form that contains a grid with the underlying data.

Note

The complete sample project How to: Display Underlying (Drill-Down) Records is available in the DevExpress Examples repository.

This example is based on the DevExpress MVVM Framework. When a user double-clicks a cell, the EventToCommand class invokes the bound ShowDrillDownDataCommand defined in the ViewModel.

To pass the event data as a parameter to the command, the EventToCommand.PassEventArgsToCommand property is set to true. The EventArgsToCellInfoConverter instance is assigned to the EventToCommand.EventArgsConverter property to convert the event data to the CellInfo parameter type required for the command.

The command calls the DialogService.ShowDialog method to invoke a custom window that displays the underlying data. The DialogService is a part of the DevExpress MVVM Framework. It is defined in XAML and specifies the DXDialogWindow that contains the GridControl bound to the CellInfo.DrillDownDataSource property.
