Summary

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

Pascal

 propertyUserData: Pointer;

Description

The current row of the dataset can have a special user-data 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.UserData := Pointer(MyObject) // Flag XYX rows.

  else

    MyCsvDataSet.UserData := nil;

  MyCsvDataSet.Next;
end; UserTag: same idea as UserData, but instead of a pointer, it's an integer.
