Hi,

I've spent months trying to solve this problem, using a Formview to enter/modify data connected to a SQL Server backend via an ObjectSource TableAdapter. After having another go tonight (an intense 6hrs+) I saw a post from the developers to say that this problem with original_{0} would be resolved in VWD Express 2005, but it didn't, even with the latest update. I've now downloaded VWD Express 2008 Beta 2 and I'm still getting the same problem. Have I missed something? I can display data but not modify it (get the above error). To say this is frustrating is an understatement.

Default OldValuesParameterFormatString should be {0} now should it not, instead of original_{0}?

Any help would be extremely appreciated.

Thanks

take a look at the parameters it wants in the error.  Usually the primary key will contain original_{primarykey}.  I would try either removing the OldValuesParameterFormatString  or do as you mention and set it to {0}.  If this doesn't help, post the actual error code with all the variable names in the error.

thanks, Peter, that's very kind of you to offer to look at the code for me. I'll have another look at it, and if I hit another brick wall, then I might take you up on your offer!

Thanks again 

Tushar
