Sorry - forgot to mention the version is: 6.303.1.8
>Setting e.ActivateOptions.ShouldBeginEdit = false doesn't stop the cell from going into edit mode when clicked.
Setting e.Cancel = true results in the following null reference exception:
System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."

This is a defect that we will correct. Until there is a version with this corrected, maybe code like this will serve your needs:
void grid_CurrentCellStartEditing(object sender, System.ComponentModel.CancelEventArgs e)
{
e.Cancel = true;
grid.UnloadArrangedCells();
grid.InvalidateVisual();
}
