WPF：在自定义控件的多个内容的主持人？ [英] WPF: Multiple content presenters in a custom control?

问题描述

我想有需要XAML的2个或更多的区域由子控件来定义一个自定义的控制 - 从这个控件继承。我不知道是否有一种方法可以定义多个contentpresenters和一个充当默认的内容演示

I'm trying to have a custom control that requires 2 or more areas of the XAML to be defined by a child control - that inherits from this control. I'm wondering if there's a way to define multiple contentpresenters and one which acts as the default content presenter

<MyControl>
      <MyControl.MyContentPresenter2>
           <Button Content="I am inside the second content presenter!"/>
      </MyControl.MyContentPresenter2>

      <Button Content="I am inside default content presenter" />
</MyControl>

这是可能的，我怎么在自定义控件的模板定义此？

Is this possible, how do I define this in the custom control's template?

推荐答案

模板只需绑定像这样单独的 ContentPresenter 实例（我只能设置一个物业在这里，但你可能会想要设置别人）：

The template can just bind the separate ContentPresenter instances like this (I've only set one property here but you'll likely want to set others):

<ContentPresenter Content="{TemplateBinding Content1}"/>
<ContentPresenter Content="{TemplateBinding Content2}"/>

控件本身应该公开内容两个属性和使用的 ContentPropertyAttribute ：

[ContentProperty("Content1")]
public class MyControl : Control
{
    // dependency properties for Content1 and Content2
    // you might also want Content1Template, Content2Template, Content1TemplateSelector, Content2TemplateSelector
}
