在Windows Phone 8中使用c#改变PanoramaItem的可见性

本文关键字：改变 PanoramaItem 可见性 Windows Phone | 更新日期: 2023-09-27 18:15:59

我正在使用c#使panoramaItem的可见性可见。默认情况下，panoramaItem被设置为折叠。见下文:

<phone:PanoramaItem Header="select" Visibility="Collapsed" x:Name="SelectGroup">
            <TextBlock Text="HI" Margin="30" FontSize="36"></TextBlock>
</phone:PanoramaItem>

现在有一个TextBlock，我已经创建了一个Tap事件:

<TextBlock x:Name="SeachBloodGroup" Text="A+" FontSize="30" Tap="BloodGroup_Tap"></TextBlock>

代码:

private void BloodGroup_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
    SelectGroup.Visibility = SelectGroup.Visibility == Visibility.Collapsed ? Visibility.Visible : Visibility.Collapsed;           
}

但是panoramaItem没有显示

在Windows Phone 8中使用c#改变PanoramaItem的可见性

试试这个:

private void BloodGroup_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
    if (SelectGroup.Visibility == System.Windows.Visibility.Collapsed)
        SelectGroup.Visibility = System.Windows.Visibility.Visible;
    else
        SelectGroup.Visibility = System.Windows.Visibility.Collapsed;
}
