Available values:
| Name | Description |
|---|---|
| PerformanceOptimized | The GridView tries to store the keys in the fastest way. When a user selects a several rows, the grid saves the selected keys. However, when a user selects all rows, the grid begins to add only unselected row keys. |
| DataIntegrityOptimized | The GridView always stores the keys of all selected rows. |
Remarks
Use the SelectionStoringMode property to specify the manner in which the control stores record selection.
If you set this property to PerfomanceOptimized, the control tries to store the keys in the fastest way: when a user selects a few records, the grid saves the selected keys. However, when a user selects all records, the grid begins to add only unselected record keys. This approach allows you to significantly increase performance, but the database integrity may be corrupted in some cases. To avoid this issue, we have added the DataIntegrityOptimized mode that always stores all selected record keys.
