How to add unbound CheckBox column at run time in WinForms GridGroupingControl?

Unbound column

To add an Unbound column in the WinForms GridGroupingControl, TableDescriptor. UnboundFields collection can be used and the CheckBox cell type can be assigned in the following way,

this.gridGroupingControl1.TableDescriptor.UnboundFields.Add("print");  this.gridGroupingControl1.TableDescriptor.Columns["print"].Appearance.AnyRecordFieldCel.CellType = "CheckBox";

Me.gridGroupingControl1.TableDescriptor.UnboundFields.Add("print")
Me.gridGroupingControl1.TableDescriptor.Columns("print").Appearance.AnyRecordFieldCel.CellType = "CheckBox"

The values of that Unbound field can be maintained through QueryValue and SaveValue events. An internal collection will be handled for displaying and updating the values.

this.gridGroupingControl1.TableDescriptor.QueryValue += new FieldValueEventHandler(unboundField_QueryValue);
private void unboundField_QueryValue(object sender, FieldValueEventArgs e)
{
    if (e.Field.Name == "print" && checkboxvalues.Contains(e.Record.Id))
    {
        e.Value = (bool)checkboxvalues[e.Record.Id];
    }
}

Private Me.gridGroupingControl1.TableDescriptor.QueryValue += New FieldValueEventHandler(AddressOf unboundField_QueryValue)
Private Sub unboundField_QueryValue(ByVal sender As Object, ByVal e As FieldValueEventArgs)
    If e.Field.Name = "print" AndAlso checkboxvalues.Contains(e.Record.Id) Then
        e.Value = CBool(checkboxvalues(e.Record.Id))
    End If
End Sub

this.gridGroupingControl1.TableDescriptor.SaveValue += new FieldValueEventHandler(unboundField_SaveValue);
private void unboundField_SaveValue(object sender, FieldValueEventArgs e)
{
    if (e.Field.Name == "print" && checkboxvalues.Contains(e.Record.Id))
    {
       checkboxvalues[e.Record.Id] = bool.Parse(e.Value.ToString());
    }
}

Private Me.gridGroupingControl1.TableDescriptor.SaveValue += New FieldValueEventHandler(AddressOf unboundField_SaveValue)
Private Sub unboundField_SaveValue(ByVal sender As Object, ByVal e As FieldValueEventArgs)
    If e.Field.Name = "print" AndAlso checkboxvalues.Contains(e.Record.Id) Then
       checkboxvalues(e.Record.Id) = Boolean.Parse(e.Value.ToString())
    End If
End Sub
