如何使用属性更改 TimePicker 格式 [英] How to change TimePicker format using properties

问题描述

我使用扩展的 wpf 工具包在我的 wpf 应用程序中使用了 TimePicker 格式.我正在使用HH:MM"格式.但问题是，允许直接从选项中选择小时的按钮，显示 24 小时格式，但我只想要 12 小时.但是我通过将 Endtime 从23:59"更改为11:59"，通过 TimePicker 的属性实现了这一点.但是那些上下按钮仍然显示小时到23.所以，如果我想达到11，我该怎么办?我可以仅通过 TimePicker 的属性来实现吗?它也没有显示一天的一部分，即上午/下午.我还想要另一个按钮，它应该向我显示这两个选项(即 AM 和 PM).请提出建议，我应该如何进行?

I've used TimePicker format in my wpf application using extended wpf toolkit. I'm using "HH:MM" format. but problem is, the button which allows to select hours directly from the options, showing 24 hours format, but I want 12 hours only. But I managed that through properties of TimePicker by changing Endtime from "23:59" to "11:59". But those up and down buttons still showing hours upto 23. so, If I want to make upto 11, what should I do? Can I achieve this by TimePicker's property only? also It's not showing part of day i.e AM/PM. I also want another button which should show me these two options (i.e AM and PM). Please suggest, how should I proceed?

我后面的代码中绑定到DateTime对象的Timepicker控件如下，

My Timepicker controls which are bound to DateTime object in my code behind are as follows,

<Window x:Class="TimeSheet.CustomView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:sys="clr-namespace:System;assembly=mscorlib"
    xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
    x:Name="Time"
    Title="CustomView" Width="596" Height="596">
<Grid>
    <StackPanel Orientation="Horizontal" Height="30" Width="596" Margin="0,137,-8,399">
        <xctk:TimePicker x:Name="StartTimeText" Value="{Binding starttime, ElementName=Time, Mode=TwoWay}" BorderThickness="0" Background="Yellow" Width="113" EndTime="11:59:0" AllowSpin="False"/>
        <xctk:TimePicker x:Name="StopTimeText" Value="{Binding stoptime, ElementName=Time, Mode=TwoWay}" BorderThickness="0" Background="Yellow" Width="115" EndTime="11:59:0" AllowSpin="False"/>
    </StackPanel>              
</Grid>
</Window>

推荐答案

使用 FormatString 属性来格式化您的显示.我认为您已经在之前的问题中涵盖了格式.您还应该将 Format 设置为 Custom.

Use the FormatString property to format your display. I think you have the formats covered in your previous questions. You should also set Format to Custom.

这里有一个建议:

<xctk:TimePicker Format="Custom" FormatString="hh:mm:ss tt" />

您应该注意，使用 HH 表示小时为您提供 24 小时格式，而 hh 将为您提供 12 小时格式.

You should note that using HH for hours gives you 24-hour format, while hh will give you a 12-hour format.

您可以在此处查看文档.
