I need to check that I have a minimum number of detail records and reject the whole lot if there aren't enough. I am trying to use the OnUpdateData event but I can't seem to get the details of the nested datasets. I have tried "MyCDS.FieldByName('NestedDSName').DataSet.RecordCount" but this returns the number of records in the master dataset - not the detail. I have also tried "MyCDS.FieldByName('NestedDSName').DataSet.DataSetField.NestedDataSet.Record Count" but although this compiles, it won't execute. There's got to be a way. I would rather use the BeforeApplyUpdates event but can't see how to do it there either. Any suggestions?
