什么是WPF最好的自由时间选择器？

我正在为WPF寻找一个简单的时间选择器控件。

• 我发现找到了这个：

Time Picker

但它有一些问题，例如你不能输入“00”，第二个零不会出现。

• Silverlight似乎有一个：

http://jesseliberty.com/2009/03/28/toolkit-control-%E2%80%93-timepicker/

但它不适用于WPF 。

• WPF工具包本身有一个DatePicker而不是TimePicker。 或者有没有办法允许用户在WPFToolkit DatePicker中输入时间和日期？ 它在SelectedDate中返回 DateTime但我没有看到如何允许用户也选择具有此控件的时间。

什么是最好的免费WPF控件，允许用户以HH：MM：SS格式输入时间？

Answer 1

如图所示，您可以轻松自行滚动。 这样，你就能得到你想要的东西。

Answer 2

我喜欢扩展WPF工具包中的控件： 链接到github上的源代码

在包中，包含DateTimeUpDown ，可用于您的目的。 如果您不想使用它的Date部分，可以将Format设置为“ShortTime”或您想要的任何格式。

希望有所帮助。

我在网上找不到一个，所以我从头开始创建它。 我不完全理解依赖属性，所以我现在省略了它们。 该控制是12小时时间选择器控制。 我是WPF的新手，所以我并不完全理解所有新的语言语法，但是这个控件将在我在家创建的项目中为我做好准备。

它支持将时间设置为DateTime或TimeSpan。

下面我将粘贴XAML和Code-Behind。 XAML

这是控制，随意根据需要进行修改。 它并不完美，但它比我发现的其他控件更好

自版本1.3.0起， MahApps库具有Timepicker控件。
