Hi, i have 2 issues with this GridPresenter

 I have a GridPresenter and i have edit mode is false.  the check boxes that are here are still able to be checked and unchecked.  Even if i put the check boxes as editable false and read only false you can still edit the check boxes. nothing i do will make this read only.

If i change edit mode on and i put the DataPresenterTextColumn  as read only it's still able to be edited, but the check boxes never update the datasourse.

why does this happen?

<Intersoft:GridPresenter x:Name="grddetails" Grid.Row="2" DataSourceID="{Binding}" ItemsSource="{Binding Users, Mode=TwoWay}" EnablePaging="Yes" AutoGenerateColumn="No" EnableContextMenu="True" Error="grddetails_Error" MouseRightButtonUp="grddetails_MouseRightButtonUp">
