如何在代码隐藏中创建日历？

I want to create an asp.net ajax calendar like this, but entirely in code-behind. How do I do it?

我想像这样创建一个asp.net ajax日历,但完全是在代码隐藏中。我该怎么做?

Edit: I only want to add the js code to the page in code-behind (eg: not in the markup)

编辑:我只想在代码隐藏中将js代码添加到页面中(例如:不在标记中)

Edit_2: I need this because I create a textbox control in a template class and want to create the calendar there (for use with the textbox)

Edit_2:我需要这个,因为我在模板类中创建了一个文本框控件,并希望在那里创建日历(用于文本框)

The ASP.NET ajax calendar you refer to is an extender, so in theory you could add it to your textbox at runtime in the code-behind. See the example below, the placeholder is vital!

您引用的ASP.NET ajax日历是一个扩展程序,因此理论上您可以在运行时在代码隐藏中将其添加到文本框中。看下面的例子,占位符是至关重要的!

I'm not sure why you would want to do this, can you give us a better idea of the need as there may be a better solution.

我不确定你为什么要这样做,你能否让我们更好地了解需求,因为可能有更好的解决方案。
