Check if data has been modified

Hi,

I try to discover if the current record has been modified, before the user scrolls to the next record.

It seams, that in the OnBeforeScroll Event the DataSet.Modified flag is always false. Even if I made changes. Does anyone know if this is a bug?

best regards,
Hans

It's quite difficult to say briefly. Use VarEqual(Field.OldValue, Field.NewValue) for determination, but keep in mind special cases with TBlobField, TBytesField, TLargeIntField and TVariantField.
