Remarks

This event occurs when the user double-clicks a cell in the Data Area. Use event data to identify the cell location, data field, whether the cell is selected or focused.

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 to show the underlying data.

Note

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

The primary data source is the Northwind database contained in the SQL Server data file NW.mdf. The application can use the BindingSource component or the LinqServerModeDataSource instance to retrieve the data from the database. A LinqServerModeDataSource data source is a queryable data source, and it forces the PivotGrid to operate in server mode. Click the Server Mode toggle switch control to switch from one data source to another.

When you double-click the PivotGrid cell, the PivotGridControl.CellDoubleClick event occurs. The following CreateDrillDownDataSource method overrides are called to obtain the list of records associated with the selected cell:

You can also click the Get Grand Total Data button to call the PivotGridControl.CreateDrillDownDataSource method and display all data records that the PivotGridControl uses to show the summarized data.
