add combo box to datagrid view

Hi Jay,

Please check the different ways listed below to add combobox in datagridview.

In WPF, adding a ComboBox inside a DataGrid is very common—and the clean way to do it is with a DataGridComboBoxColumn.

Let’s walk through it clearly

1. Basic ComboBox inside DataGrid

XAML

2. Provide ComboBox items

You need a list for the dropdown.

Option A: Static list in XAML


    
        Option 1
        Option 2
        Option 3

3. Data model (C#)

public class MyItem
{
    public string Name { get; set; }
    public string Category { get; set; }
}

4. Bind data to DataGrid

public MainWindow()
{
    InitializeComponent();

    myGrid.ItemsSource = new List
    {
        new MyItem { Name = "Item 1", Category = "Option 1" },
        new MyItem { Name = "Item 2", Category = "Option 2" }
    };
}

5. Dynamic ComboBox per row (important)

If each row has its own dropdown list:

public class MyItem
{
    public string Name { get; set; }
    public string Category { get; set; }
    public List CategoryOptions { get; set; }
}

6. Advanced (more control with template)

If you want full control (styling, events), use DataGridTemplateColumn:

Key Concepts:

SelectedItemBinding ? binds selected value to your data
ItemsSource ? dropdown list
DataGridComboBoxColumn ? quick & simple
DataGridTemplateColumn ? flexible & powerful
