[英]wp8 bind every PivotItem to different List
我已经使用Pivot controll创建了WP8应用程序。 有5个PivotItem,其中3个应绑定到3个列表或一个具有不同过滤数据的列表。 这个怎么做?
XAML:
<phone:Pivot Name="PControl" Grid.Row="1" Style="{StaticResource PivotStyle}"> <phone:PivotItem> <phone:PivotItem.Header> <Grid Height="80"> <TextBlock Text="offer" FontSize="45" Height="80" /> </Grid> </phone:PivotItem.Header> <phone:LongListSelector Margin="0,0,0,0" ItemsSource="{Binding lstOffer}"> <phone:LongListSelector.ItemTemplate> <DataTemplate> <StackPanel Margin="0,0,0,17"> <TextBlock Text="some binding" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource TextBlockMnuTekst}"/> </StackPanel> </DataTemplate> </phone:LongListSelector.ItemTemplate> </phone:LongListSelector> </phone:PivotItem> </phone:Pivot> . . . <phone:PivotItem> <phone:PivotItem.Header> <Grid Height="80"> <TextBlock Text="services" FontSize="45" Height="80" /> </Grid> </phone:PivotItem.Header> <phone:LongListSelector Margin="0,0,0,0" ItemsSource="{Binding lstServices}"> <phone:LongListSelector.ItemTemplate> <DataTemplate> <StackPanel Margin="0,0,0,17"> <TextBlock Text="some binding" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource TextBlockMnuTekst}"/> </StackPanel> </DataTemplate> </phone:LongListSelector.ItemTemplate> </phone:LongListSelector> </phone:PivotItem>
C#:
public class clsPivotData { public string Name { get; set; } public List<clsPivotItemList> PivotItemList { get; set; } public clsPivotData() { PivotItemList = new List<clsPivotItemList>(); } } public class clsPivotItemList { public string id { get; set; } public string ssubname { get; set; } public string visible { get; set; } public string icon { get; set; } public string itemType { get; set; } public string url { get; set; } public string desc { get; set; } } public partial class MainPage : PhoneApplicationPage { public ObservableCollection<clsPivotData> Items { get; set; } public static MainPage CurrentMainPage; public List<clsPivotData> lstOffer { get; set; } public List<clsPivotData> lstServices { get; set; } public List<clsPivotData> lstInfo { get; set; } // Constructor public MainPage() { InitializeComponent(); CurrentMainPage = this; // Set the data context of the listbox control to the sample data DataContext = App.ViewModel; lstOffer = new List<clsPivotData>(from i in Items where i.Name == "offer" select i); lstServices = new List<clsPivotData>(from i in Items where i.Name == "services" select i); lstInfo = new List<clsPivotData>(from i in Items where i.Name == "info" select i); . . .
我在lstOffer和lstServices中获得了正确的数据,但未显示正在加载数据,这不是问题。 我不知道如何从LongListSelector(Text = some绑定)将TextBlock绑定到属性ssubname,该属性是clsPivotItemList类的属性,而List是clsPivotData类的属性。
试试这个<TextBlock Text="{Binding ssubname}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource TextBlockMnuTekst}"/>
<Grid Datacontext="{Binding lstOffer }">
<phone:LongListSelector Margin="0,0,0,0" ItemsSource="{Binding PivotItemList }">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,17">
<TextBlock Text="{Binding ssubname}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource TextBlockMnuTekst}"/>
</StackPanel>
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
</Grid>
我终于找到了答案。 我将下一个代码放在MainViewModel类中:
public ObservableCollection<clsPivotData> Items { get; set; } public ObservableCollection<clsPivotData> lstOffer { get; set; } public ObservableCollection<clsPivotData> lstServices { get; set; } public ObservableCollection<clsPivotData> lstInfo { get; set; } // Constructor public MainViewModel() { this.Items = new ObservableCollection<clsPivotData>(); LoadData(); lstOffer = Items.Where(o => o.Name == "offer").FirstOrDefault().PivotItems; lstServices = Items.Where(o => o.Name == "service").FirstOrDefault().PivotItems; lstInfo = Items.Where(o => o.Name == "info").FirstOrDefault().PivotItems; }
在XAML中,我以这种方式插入了ListBox:
<ListBox Margin="0,0,0,0" ItemsSource="{Binding lstOffer}"> <ListBox.ItemTemplate> <DataTemplate> <ItemsControl> <StackPanel Margin="0,0,0,17"> <TextBlock Text="{Binding ssubname}" TextWrapping="Wrap" Margin="12,0,12,0" Style="{StaticResource TextBlockMnuTekst30}"/> </StackPanel> </ItemsControl> </DataTemplate> </ListBox.ItemTemplate> </ListBox> . . .
