在我的wpf應用程序中，我有兩個位於DataTemplate中的timePicker控件。在DataTemplate中設置TimePicker的日期和時間
的XAML：

我想設置日期和時間他們。我知道如果它們不在DataTemplate中，下面兩行將爲它們設置日期和時間。
StartPicker.Value = new DateTime(DateTime.Now.Year,DateTime.Now.Month,DateTime.Now.Day,DateTime.Now.Hour,DateTime.Now.Minute,DateTime.Now.Second);
EndPicker.Value = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);
因爲這些TimePickers在DataTemplate中，所以這些在我的代碼後面是不可訪問的。任何人都可以在這種情況下提出一些設置日期和時間的方法嗎？
使用數據綁定與屬性..檢查谷歌它.. – loop
是你的組合框工作.. – loop
是的。 ComboBox正在工作。 – user2622971
