Can u help me ? Best regards GUIDO Lookup the property "Unique Table" in the ado documentation. (After opening your dataset, set MyAdodataset.recordset.properties['Unique Table'].value:='MyDetailTable', or alternatively: download and use tbetteradodataset instead of tadodataset. It has a property "unique_table" that does the same.) -- Arthur Hoornweg (In order to reply per e-mail, please just remove the ".net" from my e-mail address.
