If you want to select multiple records when clicking on the cell, set the ListBoxSelectionMode as SelectionMode.MultiExtended. By default you can select the multiple records using Ctrl key. Moreover, Shift key allows user to extend existing selection by holding Shift key and clicking a cell. 
 
Code Snippet 




//Multi record selection 
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended; 
 
We have already provided UG documentation regarding the multiple ways in gridgrouping control. Please make use of the below UG,Selections UG link - https://help.syncfusion.com/windowsforms/gridgrouping/selections#selectionmode---multiextended

To achieve your requirement we suggest you to set the unbound checkbox and by using TableControlCurrentCellKeyDown and QueryCellStyleInfo event you can update the unbound checkbox column based on the selected/unselected records. Please refer the following code snippet for your reference. 
 
Code Snippet 




//Event Subscription 
this.gridGroupingControl1.TableControlCurrentCellKeyDown += GridGroupingControl1_TableControlCurrentCellKeyDown; 
 
//Event Customization 
private void GridGroupingControl1_TableControlCurrentCellKeyDown(object sender, GridTableControlKeyEventArgs e) 
{ 
  var colinex = this.gridGroupingControl1.TableDescriptor.Columns["print"].GetRelativeColumnIndex() + 1; 
  //Move currentcell to checkbox colummn record 
  this.gridGroupingControl1.TableControl.CurrentCell.MoveTo(e.TableControl.CurrentCell.RowIndex, colinex, Syncfusion.Windows.Forms.Grid.GridSetCurrentCellOptions.SetFocus); 
  this.gridGroupingControl1.Focus(); 
 
  GridStyleInfo style = e.TableControl.CurrentCell.Renderer.CurrentStyle; 
  //To check whether the current cell celltype is checkbox 
  if (style.CellType == GridCellTypeName.CheckBox)  
  { 
   this.gridGroupingControl1.QueryCellStyleInfo += GridGroupingControl1_QueryCellStyleInfo; 
  } 
} 
 
//Event Customization 
private void GridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e) 
{ 
  int rowIndex = e.TableCellIdentity.RowIndex; 
  //To update the checkbox only when the record is selected 
  if (this.gridGroupingControl1.TableModel.SelectedRanges.Contains(GridRangeInfo.Row(rowIndex)) && e.Style.CellType == GridCellTypeName.CheckBox)  
  { 
   e.Style.CellValue = true; 
   } 
   else 
   { 
    e.Style.CellValue = false; 
   } 
}
