C# - Sql Server very simple connection

Question

I am trying to connect my Sql Server database to a C# application. I want to do this without writing code, using the design part from C#.

So, I created a new Windows From application, I connected my From with my Sql Server database (setting this from DataBindings -> Text), I went to Data Sources and just drag-and-drop one table, then drag-and-drop a Binding Navigator which I bounded to my corresponding table. You can see below the result.

It takes my data from the Sql Database, but when I run it and perform a change, for example deleting a record, this change is not saved in my database. How can I make it work?

Answer 1

Firstly, you need to be prepared to write some code to perform the actions you're after.

Personally, I think you'd be better off creating your connection strings in your app.config file, creating your connection in a connection class and using a bit of script to insert, update and delete data in your database tables.

If you require some assistance doing it this way I'd be happy to help :)

I just don't believe wizards are the correct approach to these types of scenarios because projects usually get more involved after this point, in which case coding is essential.

Answer 2

looking in project / properties under settings, whether the connecting string of path to the database is connected.

for example: DataSource=(LocalDB)\\MSSQLLocalDB;AttachDbFilename= C:\\Werkzeugdatenbank\\Datenbanken\\Werkzeuge.mdf ;Integrated Security = True; Connect Timeout = 30
