What are the two selection types in WinForms GridGroupingControl?

Selection types

There are two selection types in the WinForms GridGroupingControl: they are

1. Range selection (cell-based selection)

2. Record selection

Range selection

You can turn on this selection by setting the grid.tableOptions.AllowSelections to something other than None. By this selection, you can select range of cells/columns/rows. This selection functionality raises events like the grid.TableModel.SelectionChanging/Changed.

//Inherited GridControlBase Selection
this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.Any;

'Inherited GridControlBase Selection
Me.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.Any

Record selection

This selection is a record based selection support that is specific to the GridGroupingControl. You can turn on this selection support by setting the grid.TableOptions.AllowSelections to None and setting the grid.TableOptions.ListBoxSelectionMode to something other than None. This selection support raises the grid.SelectedRecordsChanged/Changing rather than raising the grid.TableModel.SelectionChanging/Changed events.

//Record based Selection
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = System.Windows.Forms.SelectionMode.One;

'Record based Selection
Me.gridGroupingControl1.TableOptions.ListBoxSelectionMode = System.Windows.Forms.SelectionMode.One

The following screenshots illustrate record selection.
