Edit Question
Title
Body
FYI: I am running on dotnet 3.5 SP1 I am trying to retrieve the value of an identity column into my dataset after performing an update (using a SqlDataAdapter and SqlCommandBuilder). After performing SqlDataAdapter.Update(myDataset), I want to be able to read the auto-assigned value of myDataset.tables(0).Rows(0)("ID") , but it is System.DBNull (despite the fact that the row was inserted). (Note: I do not want to explicitly write a new stored procedure to do this!) One method often posted http://forums.asp.net/t/951025.aspx modifies the SqlDataAdapter.InsertCommand and UpdatedRowSource like so: SqlDataAdapter.InsertCommand.CommandText += "; SELECT MyTableID = SCOPE_IDENTITY()" InsertCommand.UpdatedRowSource = UpdateRowSource.FirstReturnedRecord Apparently, this seemed to work for many people in the past, but does not work for me. Another technique: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=619031&SiteID=1 doesn't work for me either, as after executing the SqlDataAdapter.Update, the SqlDataAdapter.InsertCommand.Parameters collection is reset to the original (losing the additional added parameter). Does anyone know the answer to this???
