Hi cho dongsik,

To wrap the text of a ComboBoxItem, you can customize the GridCellComboBoxRenderer and modify the item template of the combobox. Here is a step-by-step guide on how to achieve this:

public sealed partial class MainPage : Page


    public MainPage()




        this.dataGrid.CellRenderers.Add("ComboBox", new GridCellComboBoxRendererExt());



public class GridCellComboBoxRendererExt : GridCellComboBoxRenderer


    public GridCellComboBoxRendererExt() : base()





    public override void OnInitializeEditElement(DataColumnBase dataColumn, ComboBox uiElement, object dataContext)


        base.OnInitializeEditElement(dataColumn, uiElement, dataContext);

        uiElement.ItemTemplate = Application.Current.Resources["comboboxStyle"] as DataTemplate;






    <DataTemplate x:Key="comboboxStyle">

        <TextBlock Text="{Binding}" Width="200" TextWrapping="Wrap" />
