推荐答案

你在哪里设置Visibility.Collapsed？

Where are you setting Visibility.Collapsed?

如果您的全景项目如下：

If your panorama item is as this:

        <phone:Panorama Title="my application">
            <phone:Panorama.Background>
                <ImageBrush ImageSource="/PanoramaApp2;component/Assets/PanoramaBackground.png"/>
            </phone:Panorama.Background>

            <!--Panorama item one-->
            <phone:PanoramaItem Header="first item" x:Name="FirstItem">
                ...
            </phone:PanoramaItem>

            <!--Panorama item two-->
            <phone:PanoramaItem x:Name="SecondItem">
                ...    
            </phone:PanoramaItem>

            <!--Panorama item three-->
            <phone:PanoramaItem x:Name="ThirdItem" Header="third item" Orientation="Horizontal">
                ...    
            </phone:PanoramaItem>
        </phone:Panorama>

在代码隐藏中设置Visibility属性应该可行（我试过了它的工作原理）：

Setting the Visibility property in code-behind like this should work (I have tried and it works):

SecondItem.Visibility = Visibility.Collapsed;
