Insert and Delete Query stopped working in AccessDataSource
I have a submit button that inserts user entered data into a database. It was working perfectly fine until I migrated the project to the host server. The select query is still functional and displaying my data in the GridView (I checked by manually inserting some data into the database on the host server), I am unable to insert or delete data via the client-side page. It's an access database and I am connecting to it using the Visual Studio AccessDataSource.
Also, I don't receive any errors when loading the page or when I hit submit, its just that nothing happens.
Here is my code:

Make sure the account that is accessing the file has read and write access on the host server folder where the mdb file is located.
