在動態構建UserControl中，我format string以TextBox這種方式設置了：TextBox newTextBox = new TextBox();TempViewModel viewModel = new TempViewModel();var binding = new System.Windows.Data.Binding{    Source = viewModel,    Path = new PropertyPath("DecimalValue"),    ConverterCulture = new System.Globalization.CultureInfo("de-DE"),    StringFormat = "{0:#,##0.00}"};newTextBox.SetBinding(TextBox.TextProperty, binding);public class TempViewModel{    public decimal DecimalValue { get; set; }}到目前為止效果很好。但在添加DependencyProperty后，格式將被忽略。Dependencyproperty是這樣定義的：public class UserControl_CBOGridQuotePositions : UserControl{    private static readonly DependencyProperty Amount_QuotePos_Base_DependencyProperty =        DependencyProperty.Register("Amount_QuotePos_Base", typeof(System.Decimal), typeof(UserControl_CBOGridQuotePositions), new PropertyMetadata(0m));    public System.Decimal Amount_QuotePos_Base    {        get { return (System.Decimal)GetValue(UserControl_CBOGridQuotePositions.Amount_QuotePos_Base_DependencyProperty); }        set { SetValue(UserControl_CBOGridQuotePositions.Amount_QuotePos_Base_DependencyProperty, value); }    }    private void MakeTheBindings(DependencyProperty dependencyProperty)    {        var binding = new Binding("Amount_QuotePos_Base");        binding.Source = this; // which is the UserControl_CBOGridQuotePositions        newTextBox.SetBinding(dependencyProperty, binding);    }}有沒有辦法在 TextBox 綁定到屬性時使格式工作？
