I have a problem regarding DataGridView. I need to show a Client_Name instead of Id_client
This is the Product table and it has a relationship with the Clienttable.

I’m using Access DB and DataSet.

Answer 1

In order to avoid having to do multiple queries to get the client name for each product you should include on your query an inner join to Clients table and return the client name along with the product data.

SELECT      pro.*, cli.[Name] as ClientName 
FROM        Products pro
INNER JOIN  Clients cli ON cli.Id = pro.ClientId

We could help more if you specify your data access strategy.
