我正在开发Windows Phone 8应用程序。
在我的应用程序中,我使用List Picker .list选择器值从Web服务绑定(json格式)
我的网络服务结果返回格式
[
- {
id: "9",
name: "Pizza",
root_id: "4",
level: "1"
},
-{
id: "10",
name: "Fine Dining",
root_id: "4",
level: "1"
},
]
我的列表选择器的XAML代码
<toolkit:ListPicker x:Name="filterpicker" SelectionChanged="filterpicker_SelectionChanged" Tap="filterpicker_Tap" Foreground="White" BorderThickness="0" Margin="395,-100,0,10" Height="70" Width="60">
<toolkit:ListPicker.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" Visibility="Collapsed"/>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
<TextBlock>
<Run Text="{Binding}"/>
</TextBlock>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>
我的c#代码用于绑定
void filterwc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
var filterdata = e.Result;
var filtervalue = JsonConvert.DeserializeObject<List<filterdatas>>(filterdata);
List<string> filtercategories = new List<string>();
foreach (filterdatas budval2 in filtervalue)
{
filtercategories.Add(budval2.id); /**I need to display the name and on selectionchanged event i need to get the id value**/
}
filterpicker.ItemsSource = filtercategories;
}
如果我的问题不明确,请告诉我提供更多信息......
我需要像这样
列表选择器出来就像这样
比萨饼
美食
在SelectionChanged事件
上如果我点击披萨我需要得到“9”
如果我点击Fine Dining,我需要得到“10”
谢谢...

<toolkit:ListPicker.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding name}" Visibility="Collapsed"/>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
<TextBlock>
<Run Text="{Binding name}"/>
</TextBlock>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
代码背后:
var filterdata = e.Result;
var filtervalue = JsonConvert.DeserializeObject<List<filterdatas>>(filterdata);
filterpicker.ItemsSource = filtervalue;
选择更改事件
if(filterpicker.SelectedItem == null)
return;
filterdatas element = filterpicker.SelectedItem as filterdatas;
MessageBox.Show("This is the id:"+element.id);
