What is the best practise for this situation.

I have a grid bound to an Entity Collection. The Entity's ID field in the DB is a standard auto-numbering int.

In code I add multiple entities, but the Grid complains that there are multiple entities with ID =0.

If I save to the DB after each add and refresh it's fine of course as the ID field picks up the value that SCOPE_IDENTITY() give it.

Is there a way to get a 'fake' id that auto updates in memory, then hen saves, uses the DB's auto-numbering?

I wonder why is that, it's not the grid's business as far as I know.

Would you please elaborate more? - Is this a web app or a win app? - Is this a .NET 2.0 or .NET 1.1? - Are you using any special/3rd party grids? - Would you please post the Grid's complain text and any stack trace if available?

Thanks.

there's no 'fake' id feature build in. Could you check if you've set the grid's column to be unique or something? (as it's autonumber, that setting won't matter anyway)
