Summary

A user-defined Integer property for the currently active row in the dataset.

Pascal

 propertyUserTag: Integer;

Description

The current row of the dataset can have a special user-tag property, per row. This is helpful if you want to go through a dataset, and flag certain rows as 'selected', and for other user-defined purposes. This data is NOT stored as part of the CSV file and exists only in memory.

Examples

MyCsvDataSet.First;
whilenot  MyCsvDataSet.Eof dobegin

  if  MyCsvDataSetMYFIELD.Value='XYZ' then

    MyCsvDataSet.UserTag := 1;  // Flag XYX rows.

  else

    MyCsvDataSet.UserTag := 0;

  MyCsvDataSet.Next;
end; UserData: Same idea as UserTag, but it's a pointer.
