View 5 RepliesI'm trying to get the Update button and my Delete button to work. Please advice me accordingly on what I'm doing wrongly. And as for the delete button, I have little clue of doing it. What I want the Update button to do: Basically I have a datagridview in my form. And the DGV displays all the records I have in my mdb file. The user could edit the records directly at the DGV and when the Update button is clicked, both DGV and database gets updated.

View 4 RepliesI have problems with the updating and deleting of records in database. I'm using ObjectDataSource and the GridView to display the results in the database. Below is the codes for the update and delete (in the DAL (data access layer). BTW, I'm doing 3 tier architecture in VB.
'update the records accordingly in the database.
Public Function UpdateBooks(ByVal title As String, ByVal borrowDate As String, ByVal dueDate As String, ByVal NameBorrower As String, ByVal book_id As Integer) As Integer
Dim connectionString As String = My.Settings.dbConnection
[Code] .....
I don't know why, but every time I try to update (by clicking on the update button), every thing is not updated, the page would refresh then the records still remain the same in the GridView. As for delete, when I clicked on the 'delete' button, the record is not deleted, it still remains there.
These are the codes in the (BLL (business logic layer)):
Public Function getUpdateBooks(ByVal title As String, ByVal borrowDate As String, ByVal dueDate As String, ByVal NameBorrower As String, ByVal book_id As Integer) As Integer
Dim ds As Integer = UserDA.UpdateBooks(title, borrowDate, dueDate, NameBorrower, book_id)
Return ds
