更改longlistselector中DataTemplate内部控件的可见性

Question

我longlistselector包含datatemplate image，text和两个buttons， 现在我想做的是，当我在longlistselector中选择items时，相应的项buttons将可见

Answer 1

将您的LongListSelector与Selected item属性绑定，当您的选择被更改时，将调用Property，您可以获取选择的元素，然后更改按钮的可见性...

<ls:LongListSelector Margin="0,10,0,10" ItemsSource="{Binding attractionlist,Mode=TwoWay,UpdateSourceTrigger=Default}" SelectedItem="{Binding SelectedAttractionDetail,Mode=TwoWay,UpdateSourceTrigger=Default}" >

然后制作这样的房产..

            private ObservableCollection<AttractionDetails> _attractionlist;
            public ObservableCollection<AttractionDetails> attractionlist
            {
                get
                {
                    return _attractionlist;
                }
                set
                {
                    _attractionlist = value;
                    RaisePropertyChanged("attractionlist");

                   // Change visibility here
                }
            }
