Custom SelectionController breaks SelectCell usage

[Yogesh]

If I extend GridSelectionController (even without overriding any method), using SelectCell causes a NullReferenceException.

Will attach a test project if needed.

Hi Yogesh,

Thank you for using Syncfusion products.

We analyzed your query.Please ensure, you are overriding correct selection controller based on SfDataGrid.SelectionUnit. Please refer the below table,

SelectionUnit	SelectionController to override
Row	GridSelectionController
Cell or Any	GridCellSelectionController

If you are facing the mentioned issue after overriding right selection controller also then please update us with sample to provide better solution.

Thanks a lot. I was using GridSelectionController instead of GridCellSelectionController. That fixed it.

I have one more query. If I use a GridNumericColumn cell in the grid, a return/enter key never executes either of the ProcessKeyDown or HandleKeyDown methods but every other key like Esc or Tab does. How can I fix that?
