问题描述

我在WPF画布中有两个日期选择器。我想做的就像是航空公司网站上的日期选择器。第一日历允许用户选择出发日期，第二日历允许用户选择返回日期。假设我从datapickerA中选择11/11/2012，当我单击第二个datepickerB时， 2012/11/11之前的日期被禁用。我应该在日期选择器中放入什么？

The first calendar allow user to pick the departure date and the second calendar allow user to pick the return date. Let say i select 11/11/2012 from datapickerA, when i click on the second datepickerB, the dates before 11/11/2012 are disabled. What should i put in the datepicker?

推荐答案

您可以使用 DisplayDateStart DatePicker 的属性。它是 DependencyProperty ，因此您可以使用MVVM通过 DataContext 或通过设置 DatePicker 从第一个的 SelectedDate > DisplayDateStart DatePicker ：

You can use the DisplayDateStart property of the DatePicker. It is a DependencyProperty, so you can supply it via your DataContext using MVVM, or by setting DisplayDateStart of your second DatePicker to SelectedDate from the first DatePicker:

<DatePicker x:Name="Date1"/>
<DatePicker DisplayDateStart="{Binding ElementName=Date1, Path=SelectedDate}"/>
