How to Add Combobox to DataGridView in C#

How to Add Combobox to DataGridView in C#

Click New Project, then select Visual C# on the left, then Windows and then select Windows Forms Application. Name your project "ComboboxDataGridView" and then click OK

Next, Drag and drop a DataGridView control from the Visual Toolbox onto your form designer.

Create an Entity Framework Model First, then add Category and Product table to your EF Model

You will bind data from your Entity Framework model to both the DataGridView and the ComboBox column.

In the code-behind file of your Form1, you need to set up the DataGridView and ComboBox column programmatically.

private void Form1_Load(object sender, EventArgs e)
{
    //Get category, product data from the Northwind database
    using (NorthwindEntities db = new NorthwindEntities())
    {
        productBindingSource.DataSource = db.Products.ToList();
        categoryBindingSource.DataSource = db.Categories.ToList();
    }
}

Make sure you have your Entity Framework model created using Database First approach. Assume you have a DbContext called NorthwindEntities and two entities: Product and Category.

By following these steps, you set up a DataGridView with a ComboBox column that is bound to a list of categories from your Entity Framework model.
