如何获取ListPicker的选定项目

Question

我想确定当前在ListPicker中选择的项目的名称。我不确定在SelectionChanged事件中要做什么来获取该项目的名称。

XAML

<Grid.Resources> 
     <DataTemplate x:Name="PickerItemTemplate"> 
      <TextBlock Text="{Binding Name}"/> 
     </DataTemplate> 
    </Grid.Resources> 

<toolkit:ListPicker x:Name="ThemeListPicker" Header="{Binding Path=LocalizedResources.SettingsPage_ThemeListPicker_Header, Source={StaticResource LocalizedStrings}}" 
             ItemTemplate="{StaticResource PickerItemTemplate}" 
             SelectionChanged="ThemeListPicker_SelectionChanged"/> 

XAML.CS

protected override void OnNavigatedTo(NavigationEventArgs e) 
    { 
     base.OnNavigatedTo(e); 

     themeList = new List<Theme>(); 
     themeList.Add(new Theme() { Name = "light" }); 
     themeList.Add(new Theme() { Name = "dark" }); 
     ThemeListPicker.ItemsSource = themeList; 
    } 

private void ThemeListPicker_SelectionChanged(object sender, SelectionChangedEventArgs e) 
    { 
     //get the name of the current item in the listpicker? 
    } 

Answer 1

var item = (sender as ListPicker).SelectedItem; 

Answer 2

可能是这样的。

Theme selectedObj = ThemeListPicker.SelectedItem as Theme; 

Answer 3

下面是解此MA是帮助你。

private void ThemeListPicker_SelectionChanged(object sender, SelectionChangedEventArgs e) 
     { 
      //get the name of the current item in the listpicker? 
      string currentItemName =string.Empty; 
      Theme theme= (sender as ListPicker).SelectedItem as Theme; 
      if(theme!=null) 
      { 
      currentItemName = item.Name; 
      } 
     }
