Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v20.1.dll

Declaration

public event PivotCellEventHandler CellDoubleClick
Public Event CellDoubleClick As PivotCellEventHandler

Event Data

The CellDoubleClick event's data class is PivotCellEventArgs. The following properties provide information specific to this event:

Property Description
Bounds Gets the cell's bounds.
ColumnCustomTotal Gets the column custom total which displays the current cell.
ColumnField Gets the innermost column field which corresponds to the processed cell.
ColumnFieldIndex For internal use.
ColumnIndex Gets the visual index of the column that contains the processed cell.
ColumnValueType Gets the type of column which contains the processed cell.
Data For internal use.
DataField Gets the data field which identifies the column where the processed cell resides.
DisplayText Gets the display text of the cell currently being processed.
Focused Gets whether the processed cell is the focused cell.
Item For internal use.
RowCustomTotal Gets the row custom total which contains the current cell.
RowField Gets the innermost row field which corresponds to the processed cell.
RowFieldIndex For internal use.
RowIndex Gets the index of the row that contains the processed cell.
RowValueType Gets the type of row which contains the processed cell.
Selected Gets whether the processed cell is selected.
SummaryType Gets the summary type of the currently processed value.
SummaryValue Gets the summary value currently being processed.
Value Gets the processed cell's value.

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.

Examples

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.
