如何以编程方式执行以下操作(来自XAML):
<TextBox Name="OrderDateText"
Text="{Binding Path=OrderDate, StringFormat=dd-MM-yyyy}"
public DateTime OrderDate
现在我有以下
TextBox txtboxOrderdDate = new TextBox();
我知道我需要做一些像
这样的事情 Binding bindingOrderDate = new Binding();
bindingOrderDate.Source = "OrderDate";
但我被困在这里......不确定如何继续应用StringFormat,我也不确定SOURCE是否正确(我应该使用ElementName吗?)

让MainWindow
成为班级名称。将以下代码中的MainWindow
更改为您的班级名称。
public DateTime OrderDate
{
get { return (DateTime) GetValue(OrderDateProperty); }
set { SetValue(OrderDateProperty, value); }
}
public static readonly DependencyProperty OrderDateProperty =
DependencyProperty.Register("OrderDate",
typeof (DateTime),
typeof (MainWindow),
new PropertyMetadata(DateTime.Now, // Default value for the property
new PropertyChangedCallback(OnOrderDateChanged)));
private static void OnOrderDateChanged(object sender, DependencyPropertyChangedEventArgs args)
{
MainWindow source = (MainWindow) sender;
// Add Handling Code
DateTime newValue = (DateTime) args.NewValue;
}
public MainWindow()
{
InitializeComponent();
OrderDateText.DataContext = this;
var binding = new Binding("OrderDate")
{
StringFormat = "dd-MM-yyyy"
};
OrderDateText.SetBinding(TextBox.TextProperty, binding);
//Testing
OrderDate = DateTime.Now.AddDays(2);
}

您是否尝试将bindingOrderDate
的{{1}}属性设置为正确的格式?据MSDN称,它应该如何运作。
答案 2 :(得分:-1)
在后面的代码中定义类型为DateTime
的属性,然后绑定。

Object data = new Object();
TextBox txtboxOrderdDate = new TextBox();
Binding bindingOrderDate = new Binding("Order Date", data, "OrderDate");
bindingOrderDate.Format += new ConvertEventHandler(DecimalToCurrencyString);
txtboxOrderdDate.DataBindings.Add(bindingOrderDate);
private void DecimalToCurrencyString(object sender, ConvertEventArgs cevent)
{
if (cevent.DesiredType != typeof(string)) return;
cevent.Value = ((decimal)cevent.Value).ToString("dd-MM-yyyy");
}
