Question

你能告诉我如何设置我的usercontrol的宽度（这取决于主窗口）。通过PRISM？

我尝试在Xaml中使用Application.Current.Window.Width，但它在那里不起作用。

这是我的代码：

    <prism:InteractionRequestTrigger SourceObject="{Binding ShowExpressionHelpWindowNotificationRequest}">
        <prism:PopupWindowAction IsModal="True" CenterOverAssociatedObject="True" WindowStartupLocation="CenterOwner">
            <prism:PopupWindowAction.WindowContent>
             <vm:SpreadSheetUserControl Width="{Binding Source={x:Static Application.Current.MainWindow.Width}}"/>
            </prism:PopupWindowAction.WindowContent>
        </prism:PopupWindowAction>
    </prism:InteractionRequestTrigger>

任何非棱镜解决方案都可以。

提前谢谢。

试试这个：

<prism:InteractionRequestTrigger SourceObject="{Binding ShowExpressionHelpWindowNotificationRequest}">
    <prism:PopupWindowAction IsModal="True" CenterOverAssociatedObject="True" WindowStartupLocation="CenterOwner"
        xmlns:win="clr-namespace:System.Windows;assembly=PresentationFramework">
        <prism:PopupWindowAction.WindowContent>
            <vm:SpreadSheetUserControl Width="{Binding Path=MainWindow.Width, Source={x:Static win:Application.Current}}"/>
        </prism:PopupWindowAction.WindowContent>
    </prism:PopupWindowAction>
</prism:InteractionRequestTrigger>

如何设置我的Dialog的大小取决于MainWindow（明智的MVVM）
