 ## About the example
 
 This example illustrates how to create a custom selection controller for the SfDataGrid to skip selection for the caption summary and group summary rows.

You can skip the pointer selection and arrow key navigation for these summary rows by creating a custom SelectionController and overriding the [HandlePointerOperations](https://help.syncfusion.com/cr/windowsforms/Syncfusion.WinForms.DataGrid.Interactivity.RowSelectionController.html#Syncfusion_WinForms_DataGrid_Interactivity_RowSelectionController_HandlePointerOperations_Syncfusion_WinForms_DataGrid_Events_DataGridPointerEventArgs_Syncfusion_WinForms_GridCommon_ScrollAxis_RowColumnIndex_) and [ProcessArrowKeysForSingleMultipleSelection](https://help.syncfusion.com/cr/windowsforms/Syncfusion.WinForms.DataGrid.Interactivity.RowSelectionController.html#Syncfusion_WinForms_DataGrid_Interactivity_RowSelectionController_ProcessArrowKeysForSingleMultipleSelection_System_Windows_Forms_KeyEventArgs_) methods respectively.
