    Extra properties in DataTable returned by web service

    Hi!

    I want to return DataTable from web service method. This method
    generate xml with schema and data. Is there any way to retrun more
    informations about columns? If I want to get maxLength there is no
    problem because DataColum has property MaxLength, but I need more
    (e.g. color, mask..) Thx for help!

      szwejk,

      I'm not sure what you mean, as the DataTable doesn't have any color or
      mask properties.

      Whatever this information is you are trying to return, you can create a
      different type that includes the information from the DataTable as well as
      the extra information you have which isn't part of the DataTable.

          I know that DataTable doesn't have properties that I need. But I'd
          like to ask is there any simple way (e.g. like override DataTable,
          DataColum or prepere special types in data columns or any other ideas)
          when web service can retrun additional informations in schema about
          data in every column?

              szwejk,

              No, you can't. The DataSet doesn't have the hooks to insert this extra
              data, and it would affect the schema ^and^ the XML that is output by the
              DataSet.

              However, you can transform the XML that the DataSet produces and append
              the extra data you need (in the schema, and in the XML instance).
