Welcome to the FoxLearn
Today we will learn how to fill combobox and datagridview automatically
First, You need to download the Northwind database, then restore the database to SQL Server
We will design a simple UI that allows you to select the category from the ComboBox
then displays a list of products corresponding to the category selected in DataGridView
We will use entity framework to retrieve data from the Northwind database
Entity Framework is an object-relational mapper that enables .NET developers to work with relational data using domain-specific objects
It eliminates the need for most of the data-access code that developers usually need to write
Entity Framework allows you to create a model by writing code or using boxes and lines in the Entity Framework Designer
Both of these approaches can be used to target an existing database or create a new database
