Wpf 如何在选定日期自动关闭telerik RadDateTimePicker

控件声明如下：

 <telerik:RadDateTimePicker InputMode="DateTimePicker"
                            IsTabStop="False"
                            Height="36"
                            Focusable="False"
                            Validation.ErrorTemplate="{x:Null}"
                            SelectionOnFocus="SelectAll"
                            x:Name="OutwardStartDate"
                            BorderThickness="2,2,2,2"
                            SelectedValue="{Binding OutwardDepartureDate, Mode=TwoWay, ValidatesOnDataErrors=true,
                                                                     NotifyOnValidationError=true}" >

<telerik:RadDateTimePicker InputMode="DateTimePicker"
                           SelectionChanged="RadDateTimePicker_SelectionChanged"
                           IsTabStop="False"
                           Height="36"
                           Focusable="False"
                           Validation.ErrorTemplate="{x:Null}"
                           SelectionOnFocus="SelectAll"
                           x:Name="OutwardStartDate"
                           BorderThickness="2,2,2,2"
                           SelectedValue="{Binding OutwardDepartureDate,
                                               Mode=TwoWay,
                                               ValidatesOnDataErrors=true,
                                               NotifyOnValidationError=true}">

我找不到任何XAML属性，无法在选择日期时自动关闭此控件。我偶然发现了这个问题，但是这个问题是5年前提出的，目前没有一个答案解决了我的问题。

你可以简单地连接到选择更改事件

在您的XAML中，如下所示：

 <telerik:RadDateTimePicker InputMode="DateTimePicker"
                            IsTabStop="False"
                            Height="36"
                            Focusable="False"
                            Validation.ErrorTemplate="{x:Null}"
                            SelectionOnFocus="SelectAll"
                            x:Name="OutwardStartDate"
                            BorderThickness="2,2,2,2"
                            SelectedValue="{Binding OutwardDepartureDate, Mode=TwoWay, ValidatesOnDataErrors=true,
                                                                     NotifyOnValidationError=true}" >

<telerik:RadDateTimePicker InputMode="DateTimePicker"
                           SelectionChanged="RadDateTimePicker_SelectionChanged"
                           IsTabStop="False"
                           Height="36"
                           Focusable="False"
                           Validation.ErrorTemplate="{x:Null}"
                           SelectionOnFocus="SelectAll"
                           x:Name="OutwardStartDate"
                           BorderThickness="2,2,2,2"
                           SelectedValue="{Binding OutwardDepartureDate,
                                               Mode=TwoWay,
                                               ValidatesOnDataErrors=true,
                                               NotifyOnValidationError=true}">
