/// This method is provided as an example, a starting point for you to modify

///
/// As the name implies, the algorithm looks at data rows to find detail grids
/// and their cplumns. It does not scan detail grid templates. There are, however, limitations
/// to this algorithm, especially when GridControl.SynchronizeDetailGrids is false.
/// Please look at the block comments in the code below for details.
///
/// The algorithm does not compute a 'fancy' column title for the detail grid
/// columns, it uses the column object's title.
///
/// Understand that Xceed does not guarantee that detail columns will show up
/// correctly in the "Column Settings" list of this Form nor will we provide
/// support for the code in this particular method. It is provided
/// as a sample, an example you can expand to suit to the complexity of your grids
