Changing the Visibility of PanoramaItem using C# in Windows Phone 8

Question

I am enabling the visibility of a panoramaItem to visible using C#. As a default the panoramaItem is set to Collapsed. See below:

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

Now there is a TextBlock and I have created a Tap event:

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

Code:

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

But the panoramaItem is not showing.

Answer 1

Try this:

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;
}
