Hello, I'm receiving this strange error when I have a DBGrid connected to a Client dataset which in turn is connected to a persistent dataset field on a datamodule. Any clue what the problem may be?

Any clue what the problem may be? Not from the information you have provided, no. What version of Delphi are you using? What data access layer are you using (dbexpress, ADO,etc)? I have no idea what you mean by: 'Client dataset which in turn is connected to a persistent dataset field on a datamodule'. Are you using Aggregates? Are you using Calculated/InternalCalc fields? Since this posting is in the multi-tier NG I assume you have a seperate appserver and client app? What DSP.Options settings are you using? -- Dave Rowntree Back to top Andrea Raimondi Guest Posted: Fri Apr 16, 2004 11:54 am    Post subject: Re: "At the beginning of table" error... what the @#! Err.. I sorted this by moving the secondary CDS on the datamodule instead of having it on the inherited form. I posted here since I had no clue about where to post issues related to Client Dataset's usage, even though not in a multitier situation. Thus... is there a more appropriate group? Since I have other questions and things here are getting quite nasty...

Glad you solved your problem. Quote: I posted here since I had no clue about where to post issues related to Client Dataset's usage, even though not in a multitier situation. Thus... is there a more appropriate group? CDS is part of MIDAS(datasnap). borland.public.datasnap would be appropriate for CDS questions. Questions related to datasnap in a multi-tier environment could be posted here or datasnap, whichever you feel is most appropriate.

If you mean my questions to you in an attempt to help solve your problem, then I assure you there was no malice intended.
