The total count of selected rows: 0 (stored selected rows: 0, stored unselected rows: 0)

Enable multiple selection mode with optimized performance if the Data Grid contains a significant number of rows. To do this, set the SelectionMode property to DataGridSelectionMode.OptimizedMultipleSelection and specify the KeyFieldName property.

In this mode, the Data Grid does not store row data objects and information about all the selected rows. The Data Grid stores row key values instead. If you select all rows in the Data Grid UI or in code, and then unselect rows, the component stores keys of unselected rows only (and vice versa). This mode reduces the amount of stored data and increases performance, but may corrupt database integrity.

Add the DxDataGridSelectionColumn to select data rows with checkboxes. Set the SelectAllMode property to AllPages to select all data rows simultaneously with the Select All checkbox. To track selection changes in this mode, use the OptimizedMultipleSelectionChanged event.
