通过主窗口为另一个用户控件创建用户控件实例

问题描述：

目标：

点击用户控件usercontrol_menu上的Kassa按钮后，用户控件usercontrol_kassa将显示在主窗口中。

问题：

我很难找到正确的源代码来实现它。最近的源代码位于下方。

我也相信你需要使用控制框架，但我不知道如何在这种情况下使用它。（ http://www.mindstick.com/Articles/ f3ab29d9-8e26-4b01-a0b8-5b41521f9bfc /？帧％20控制％20in％20WPF [ ^ ]）

建议检索主窗口的实例然后在usercontrol_menu的按钮Kassa中创建一个新的usercontrol_kassa实例。

信息：

- usercontrol_menu是三个菜单按钮。

- 主窗口将包含两个用户控件（usercontrol_menu和usercontrol_kassa）。

- 单击Kassa按钮后，您应该启用创建新实例usercontrol_kassa，它应该显示在主窗口内。

- 主Windows，usercontrol_menu和usercontrol_kassa有他们自己的项目我n VS 2013.

Goal:
After clicking on the Kassa button from the user control usercontrol_menu, the user control usercontrol_kassa shall be displayed in the mainwindows.

Problem:
I have difficult to find a correct source code to implement it. The closest source code is located below.

I also believe that you need to use control frame but I don't know how to use it in this context. (http://www.mindstick.com/Articles/f3ab29d9-8e26-4b01-a0b8-5b41521f9bfc/?Frame%20control%20in%20WPF[^])

A suggestion is to retrieve the instance of main window and then create a new instance of usercontrol_kassa inside of usercontrol_menu's button Kassa.

Information:
- usercontrol_menu is menu with three buttons.
- The main windows will contain totally two user control (usercontrol_menu and usercontrol_kassa).
- After you have click the Kassa button you should enable to create a new instance of usercontrol_kassa and it should be displayed inside of mainwindows.
- main Windows, usercontrol_menu and usercontrol_kassa has¨their own project in VS 2013.

您好Deelll，

您只需要使用占位符进行区域管理即可例如：

MainWindow.xaml：

Hi Deelll,

You just need to use region management by placeholders for example:

MainWindow.xaml:

<Window x:Class="WpfApplication10.MainWindow"

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

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

        Title="MainWindow" Height="350" Width="525">
    <DockPanel LastChildFill="True">
        <ToolBar DockPanel.Dock="Top">
            <Button Content="UserControl1" Click="Button1_Click" />
            <Button Content="UserControl2" Click="Button2_Click" />
        </ToolBar>
        <ContentPresenter x:Name="workspacePlaceHolder" />
    </DockPanel>
</Window>

b $ b

代码落后：

Code behind:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button1_Click(object sender, RoutedEventArgs e)
    {
        this.workspacePlaceHolder.Content = new UserControl1();
    }

    private void Button2_Click(object sender, RoutedEventArgs e)
    {
        this.workspacePlaceHolder.Content = new UserControl2();
    }
}

最好的问候，

Shai
