Bill,

>Thanks for your answers. When I stepped thru I found that my validation rules weren't checking for the deleted status on the rowset. This is the code actually throwing the exeception:

>this.ValidateName(dr["cname1"].ToString());

Right...so, if you turn off ImmediateDelete you have to make sure all code you write checks a DataRow's RowState before attempting to access its data. There are some code samples that demonstrate how to do this in the MM .NET Dev Guide topic "ImmediateDelete: Immediately Deleting from the Database".

Best Regards,
