使用按钮切换列表框的可见性？

Question

  

可能重复：
  How can I change listbox item’s visibility property in wp7?

你能帮我用按钮切换列表框的可见性吗？

这就是我所拥有的：

private void button3_Click(object sender, RoutedEventArgs e)
{
    listbox1.Visibility = Visibility.Visible;
    if (listbox1.Visibility = Visibility.Collapsed) ;
    {
       Visibility.Visible = true;
    }
}

Answer 1

虽然不像scartag的答案那样简洁，但是SilverLight和WPF现在有了Visibility属性，这就是使用bool设置可见性的日子。

private void button3_Click(object sender, RoutedEventArgs e)
{

    if (listbox1.Visibility == Visibility.Collapsed) 
    {
        listbox1.Visibility = Visibility.Visible ;
    }
    else
        listbox1.Visibility = Visibility.Collapsed;
}

Answer 2

private void button3_Click(object sender, RoutedEventArgs e)
{
   listbox1.Visibility = listbox1.Visibility == Visibility.Visible? Visibility.Collapsed : Visibility.Visible;        
}
