将子项添加到用户控件 [英] Add child to user control

问题描述

如何在设计视图中将控件添加到WpF中的用户控件？

解决方案

我想我理解你的意思：如何创建一个UserControl，其中包含一个内容：

 [ContentProperty（  PlaceHolder）] 
  public   partial   class  UserControl1：UserControl 
 {
  public  UserControl1（）
 {
 InitializeComponent（）; 
} 
 
  public   object  PlaceHolder 
 {
  get  
 {
  return  此 .contentPresenter.Content; 
} 
 设置 
 {
 此 .contentPresenter .Content =  value ; 
} 
} 
} 

 <   UserControl     x：Class   =  WpfApplication9.UserControl1  
   
                             xmlns   =  http://schemas.microsoft.com/winfx/2006/xaml/presentation  
   
              < span class =code-attribute>               xmlns：x   =  http://schemas.microsoft.com/ winfx / 2006 / xaml  
   
        < span class =code-attribute>                     xmlns ：mc   =  http://schemas.openxmlformats.org/markup-compatibility/2006    
   
                             xmlns：d   =  http： //schemas.microsoft.com/expression/blend/2008\"   
   
                             mc：可忽略  =  d    
   
                             d：DesignHeight   =  300    d：DesignWidth   =  300 >  
 <   DockPanel     LastChildFill   =  True >  
 <   Border    已删除  =  Plum    DockPanel.Dock   =  Top   高度  =  50    /  >  
 <   Border    已移除  = 蓝色    DockPanel.Dock   = 底部   高度  =  50    /  >  
 <   ContentPresenter     x：名称  =  contentPresenter    /  >  
 <   / DockPanel  >  
 <   / UserControl  >  

How to add controls to a user control in WpF in the design view?

解决方案

Hi,

I think that I understand what you mean: How to create a UserControl with a place for his content:

[ContentProperty("PlaceHolder")]
public partial class UserControl1 : UserControl
{
    public UserControl1()
    {
        InitializeComponent();
    }

    public object PlaceHolder
    {
        get
        {
            return this.contentPresenter.Content;
        }
        set
        {
            this.contentPresenter.Content = value;
        }
    }
}

<UserControl x:Class="WpfApplication9.UserControl1"

             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 

             mc:Ignorable="d" 

             d:DesignHeight="300" d:DesignWidth="300">
    <DockPanel LastChildFill="True">
        <Border removed="Plum" DockPanel.Dock="Top" Height="50" />
        <Border removed="Blue" DockPanel.Dock="Bottom" Height="50" />
        <ContentPresenter x:Name="contentPresenter" />
    </DockPanel>
</UserControl>
