如何在WPF中创建基页?

I have decided that all my WPF pages need to register a routed event. Rather than include

我已经决定我所有的WPF页面都需要注册一个路由事件。而不是包括

public static readonly RoutedEvent MyEvent= EventManager.RegisterRoutedEvent("MyEvent", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(BasePage));

on every page, I decided to create a base page (named BasePage). I put the above line of code in my base page and then changed a few of my other pages to derive from BasePage. I can't get past this error:

在每个页面上，我决定创建一个基本页面(名为BasePage)。我将上面一行代码放在我的基本页面中，然后更改了一些其他页面以派生自BasePage。我无法克服这个错误:

Error 12 'CTS.iDocV7.BasePage' cannot be the root of a XAML file because it was defined using XAML. Line 1 Position 22. C:\Work\iDoc7\CTS.iDocV7\UI\Quality\QualityControlQueuePage.xaml 1 22 CTS.iDocV7

12“CTS.iDocV7错误。BasePage不能是XAML文件的根，因为它是用XAML定义的。1号线位置22。C:\ \工作iDoc7 \ CTS.iDocV7 \ UI \ \ QualityControlQueuePage质量。xaml 1 22 CTS.iDocV7

Does anyone know how to best create a base page when I can put events, properties, methods, etc that I want to be able to use from any wpf page?

当我可以在任何wpf页面上放置我想要使用的事件、属性、方法等时，有人知道如何最好地创建基页吗?

Here's how I've done this in my current project.

以下是我在当前项目中的做法。

First I've defined a class (as @Daren Thomas said - just a plain old C# class, no associated XAML file), like this (and yes, this is a real class - best not to ask):

首先，我定义了一个类(@Daren Thomas说——只是一个普通的老c#类，没有关联的XAML文件)，像这样(是的，这是一个真正的类——最好不要问):

public class PigFinderPage : Page
{
    /* add custom events and properties here */
}

Then I create a new Page and change its XAML declaration to this:

然后我创建一个新页面并将其XAML声明更改为以下内容:

<my:PigFinderPage x:Class="Qaf.PigFM.WindowsClient.PenSearchPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:my="clr-namespace:Qaf.PigFM.WindowsClient"
    />

So I declare it as a PigFinderPage in the "my" namespace. Any page-wide resources you need have to be declared using a similar syntax:

因此，我将它声明为“my”名称空间中的PigFinderPage。您需要使用类似的语法声明任何页面范围的资源:

<my:PigFinderPage.Resources>
    <!-- your resources go here -->
</my:PigFinderPage.Resources>

Lastly, switch to the code-behind for this new page, and change its class declaration so that it derives from your custom class rather than directly from Page, like this:

最后，切换到这个新页面的代码背后，并更改它的类声明，使它从您的自定义类派生，而不是直接从页面派生，如下所示:

public partial class EarmarkSearchPage : PigFinderPage

Remember to keep it as a partial class.

记住把它作为部分类。

That's working a treat for me - I can define a bunch of custom properties and events back in "PigFinderPage" and use them in all the descendants.

这对我来说是一种享受——我可以在“PigFinderPage”中定义一组自定义属性和事件，并在所有的后代中使用它们。

Also, have a look at Attached Events and see if you can attach your event to every Page in your app. Might be easier than a custom intermediary class.

另外，看看附件中的事件，看看是否可以将事件附加到应用程序的每个页面上。

#3

I'm not sure on this one, but looking at your error, I would try to define the base class with just c# (.cs) code - do not create one with XAML, just a standard .cs file that extends the WPF Page class.

我不太确定，但是看看您的错误，我将尝试使用c# (.cs)代码定义基类——不要使用XAML创建基类，而是使用扩展WPF页面类的标准.cs文件。

Here is a tutorial too ! it's pretty simple and easy.

这里还有一个教程!非常简单。

Little update : I just tried to do it, and it didn't work. He is what I changed to solve the problem:

小更新:我只是试着去做，但是没有成功。他就是我为了解决问题而改变的人:

1.In many forums, you will read that the sub pages must inherit from a simple cs class, without XAML. Though it works. I do inherit from a normal XAML page without any problem.

1。在许多论坛中，您将看到子页面必须继承一个简单的cs类，而不包含XAML。虽然它的工作原理。我确实继承了一个正常的XAML页面，没有任何问题。

2.I replaced the following code :

2。我替换了以下代码:

<my:PigFinderPage x:Class="Qaf.PigFM.WindowsClient.PenSearchPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:my="clr-namespace:Qaf.PigFM.WindowsClient"
/>

with

与

<my:PigFinderPage x:Class="Qaf.PigFM.WindowsClient.PenSearchPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:my="using:Qaf.PigFM.WindowsClient"
/>

because when I had "clr-namespace" instead of "using", the Intellisense could recognize PigFinderPage, but not the compiler.

因为当我使用“clr-namespace”而不是“using”时，智能感知可以识别PigFinderPage，但不能识别编译器。
