Hi Willy,

There is no point in calling the constructor for an UltraGridColumn. All of the constructors are used by the grid for deserialization. The only way to properly add columns into a grid band is to bind the grid to a datasource (in which case the grid will create the columns for you automatically). You can also use the band.Columns.Add method to add unbound columns, but you must have a datasource first for this to work.

Thanks.  But I still could not find the descriptions about the constructors.  E.g.

        public UltraGridColumn(string key, int unboundRelativePosition);

What is the argument unboundRelativePosition?  When would you use that?

Thanks,

The link does not work.  Any update?

Thanks, I eventually found that and was able to answer my question.
