提问by FukYouAll
I have an UserControlthat shows a window without an icon in the Taskbar, the problem is when the main window lost the focus and get it again the window without taskbar icon is behind the main window and is difficult show it in front again, this issue is solved using window.Owner = this;when the class is a window, but when is UserControlor other type (e.g. ListBoxItem, Viewbox) I can't do this. I tried to do this control.Owner = (Window)this;but the result throws an exception that a Gridcannot be converted into a Window
我有一个UserControl在任务栏中显示没有图标的窗口，问题是当主窗口失去焦点并再次获得它时，没有任务栏图标的窗口在主窗口后面并且很难再次显示在前面，这个问题是window.Owner = this;当类是窗口时使用解决了，但是当是UserControl或其他类型（例如ListBoxItem，Viewbox）我不能这样做。我试图这样做，control.Owner = (Window)this;但结果引发了一个Grid无法转换为 a的异常Window

for (int index=0;index< App.Current.Windows.Count;index++ )
{
if (App.Current.Windows[index].Title == "MyWindow")
control.Owner = App.Current.Windows[index];
}
here Title is the Title of Window which you want to set as owner.
这里的标题是您要设置为所有者的窗口标题。
