How To Add, Delete And Update Database Using Datagridview
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.

I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.
