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.
