可以包含其他控件的 C# 用户控件(使用时) [英] C# User Control that can contain other Controls (when using it)

问题描述

我为 ASP 找到了有关此问题的一些信息，但对我没有太大帮助...

I found something about this issue for ASP, but it didn't help me much ...

我想做的是以下内容:我想创建一个用户控件，它有一个集合作为属性和按钮来浏览这个集合.我希望能够将此用户控件绑定到一个集合并在其上显示不同的控件(包含来自该集合的数据).就像您在 MS Access 中表单下边缘的内容一样......

What I'd like to do is the following: I want to create a user control that has a collection as property and buttons to navigate through this collection. I want to be able to bind this user control to a collection and display different controls on it (containing data from that collection). Like what you had in MS Access on the lower edge of a form ...

更准确地说:

当我在我的应用程序中实际使用控件时(在我创建它之后)，我希望能够在 <myControly> 和如果我现在这样做，我的用户控件上的控件就会消失.

When I actually use the control in my application (after I created it), I want to be able to add multiple controls to it (textboxes, labels etc) between the <myControly> and </mycontrol> If I do that now, the controls on my user control disappear.

推荐答案

以下是实现您想要的一种方式的示例:

Here is an example of one way to do what you want:

一、代码——UserControl1.xaml.cs

First, the code - UserControl1.xaml.cs

public partial class UserControl1 : UserControl
{
    public static readonly DependencyProperty MyContentProperty =
        DependencyProperty.Register("MyContent", typeof(object), typeof(UserControl1));


    public UserControl1()
    {
        InitializeComponent();
    }

    public object MyContent
    {
        get { return GetValue(MyContentProperty); }
        set { SetValue(MyContentProperty, value); }
    }
}

以及用户控件的 XAML - UserControl1.xaml

And the user control's XAML - UserControl1.xaml

<UserControl x:Class="InCtrl.UserControl1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Height="300" Width="300" Name="MyCtrl">
    <StackPanel>
        <Button Content="Up"/>
        <ContentPresenter Content="{Binding ElementName=MyCtrl, Path=MyContent}"/>
        <Button Content="Down"/>
    </StackPanel>
</UserControl>

最后，使用我们美妙的新控件的 xaml:

And finally, the xaml to use our wonderful new control:

<Window x:Class="InCtrl.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:me="clr-namespace:InCtrl"
    Title="Window1" Height="300" Width="300">
    <Grid>
        <me:UserControl1>
            <me:UserControl1.MyContent>
                <Button Content="Middle"/>
            </me:UserControl1.MyContent>
        </me:UserControl1>
    </Grid>
</Window>
