I want to set Date and Time for them. I know that following two lines will set date and time for them if, they are not inside DataTemplate.
我想为他们设置日期和时间。我知道如果它们不在DataTemplate中，那么下面两行将为它们设置日期和时间。
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);
Because these TimePickers are inside DataTemplate, these are not accesible in my code behind. Can anyone suggest some ways for setting date and time in this situation?
因为这些TimePickers在DataTemplate中，所以这些在我的代码后面是不可访问的。在这种情况下，有人可以建议一些设置日期和时间的方法吗？

i think i got the solution actually what is happening here is this. you have set your ListBox.ItemsSource property to some list or collection so your ListBoxItem Datacontext is set to this list and hence its EditableDataTemplate that contain TimePicker search its binding properties(startValue and endValue) in your List or Collection but actually these property is outside the List or in your page.cs.so you have to set the Relativesource property of TimePIcker like this ..
我想我得到的解决方案实际上这里发生的是这个。您已将ListBox.ItemsSource属性设置为某个列表或集合，因此ListBoxItem Datacontext设置为此列表，因此其包含TimePicker的EditableDataTemplate在List或Collection中搜索其绑定属性（startValue和endValue），但实际上这些属性位于列表或在你的page.cs.so你必须像这样设置TimePIcker的Relativesource属性..
<DataTemplate x:Key="sample" >
<xctk:TimePicker Name="StartPicker" Value="{Binding DateTime, Mode=TwoWay,RelativeSource={RelativeSource AncestorType={x:Type Window}}}" Format="Custom" FormatString="hh:mm tt" Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="100" EndTime="11:59:0"/>
</DataTemplate>
if you want all the item's startTime and EndTime to be different then make a separate class that contain StartTime and EndTime Property. and make a list of these objects and bind that list to your listBox ..hope you getting this..sorry for my bad english
如果您希望所有项的startTime和EndTime不同，则创建一个包含StartTime和EndTime属性的单独类。并列出这些对象并将该列表绑定到您的listBox ..希望你得到这个......我的英语不好
