如何访问 datepicker 以便我可以对其执行验证。

Answer 1

您的网格是某些用户控件/窗口的一部分，对吗？

<DatePicker SelectedDateFormat="Short" Text="{Binding Birthday}" Name="datepicker1"
Loaded="YourEvent"></DatePicker>

只需在 DatePicker 上创建事件，然后在事件中加载

private void YourEvent(object sender, System.Windows.RoutedEventArgs e)
{
  var datePicker =  sender as DatePicker;
  //then apply your logic.
}
