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.InitializeComponent(); this.dataGrid.CellRenderers.Remove("ComboBox"); 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;
} } |
App.xaml
|
<Application.Resources> <DataTemplate x:Key="comboboxStyle"> <TextBlock Text="{Binding}" Width="200" TextWrapping="Wrap" /> </DataTemplate> </Application.Resources> |
