Welcome to the FoxLearn
Today we will learn how to link Combobox with database values
First, We will design a simple UI allows you to select a category from a Combobox and display a product list in a DataGridView based on the values selected from a Combobox
We will use entity framework to retrieve data from the category and product table in 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
You can download the northwind database below this video
