在运行时将usercontrol设置为另一个窗口的内容

I have a window that have a user control. This user control has a button which maximize the user control to full screen.

我有一个具有用户控件的窗口。该用户控件具有一个按钮,可将用户控制最大化为全屏。

For achieving this I have created a temporary window which I scale to current screen bounds and set it content to the user control.

为了实现这一点,我创建了一个临时窗口,我可以缩放到当前屏幕边界并将其内容设置为用户控件。

private void OnBtnMaximizeClick(object sender, RoutedEventArgs e)
    {
      if (this.btnMaximize.IsChecked == true)
      {
        if (tempfullScreenWindow == null)
        {
          tempfullScreenWindow = new Window();
          tempfullScreenWindow.WindowStyle = WindowStyle.None;
          tempfullScreenWindow.ResizeMode = ResizeMode.NoResize;
        }
        var ownerWindow = Window.GetWindow(this);

        Screen screen = this.GetContainingScreen(ownerWindow);

        tempfullScreenWindow.Left = screen.WorkingArea.Left;
        tempfullScreenWindow.Top = screen.WorkingArea.Top;
        tempfullScreenWindow.Width = screen.Bounds.Width;
        tempfullScreenWindow.Height = screen.Bounds.Height;

        // InvalidOperationException comes here (Specified element is already the logical child of another element. Disconnect it first.)
        tempfullScreenWindow.Content = this;  

        tempfullScreenWindow.Owner = ownerWindow;
        tempfullScreenWindow.ShowDialog();
      }
      else
      {
        if (tempfullScreenWindow != null)
        {
          tempfullScreenWindow.Close();
        }
      }
    }

How can I set the usercontrol as content of the newly created window, by detaching it from owner window and when temp window is closed, re-attach the same to parent window.

如何将usercontrol设置为新创建窗口的内容,方法是将其从所有者窗口中分离出来,当临时窗口关闭时,将其重新附加到父窗口。

2 个解决方案

#1

Use

mywindow.Content = new MyuserControl();

Make sure for a control can have only one parent at a time. Detach from first window first and then attach it to other.

确保控件一次只能有一个父级。首先从第一个窗口分离,然后将其附加到其他窗口。

Why is it so complicated?

为什么这么复杂?

You just need to switch current host form to the fullscreen mode.

您只需将当前主机窗体切换到全屏模式即可。

public void GoToFullScreen()
{
  this.FormBorderStyle = FormBorderStyle.None;
  this.WindowSate = FormWindowState.Maximized;
}

Use

mywindow.Content = new MyuserControl();
