Question

Is there any method to populate a dataGridView on a form from another class? The functions I use to connect and run queries to the DB are in a class, but I want the results to be showed in the main form. How can I do this?

Answer 1

Set the methods that you want to access as public.
If the class is in another project, you may have to add a reference to it in your current project.

Once the method is public, do something like this:

datagridview.DataSource = yourClass.GetData();
