数据未在Windows应用商店应用中显示形式DataBinding
我正在开发一个Windows应用商店应用。我正在设置gridview的DataContext。一些数据显示其他人没有显示。虽然我可以在反序列化的类中看到数据。
这是我下载JSON的代码：
private async void loadData(string Id, Order data)
{
HttpClient http = new HttpClient();
http.BaseAddress = new Uri(BASE_URL);
string partial_url = "rest/admin/order/info.json?id=" + Id;
System.Net.Http.HttpResponseMessage response = await http.GetAsync(partial_url);
SingleOrder orderData = new SingleOrder();
response.EnsureSuccessStatusCode();
if (response.IsSuccessStatusCode)
{
string jsonMessage;
using (Stream responseStream = await response.Content.ReadAsStreamAsync())
{
jsonMessage = new StreamReader(responseStream).ReadToEnd();
orderData = JsonConvert.DeserializeObject<SingleOrder>(jsonMessage);
OrderDetailsView.DataContext = orderData.order;
}
}
else
{
MessageDialog message = new MessageDialog("Internal server error occured!", "Error!");
UICommand okCommand = new UICommand("Okay");
message.Commands.Add(okCommand);
await message.ShowAsync();
}
}
我可以在这里看到数据：
我的xaml是：

我的输出是：
在发货时，只有结算ID会显示其他字段，例如address_line1 address_line2，但没有显示。
这是singleOrder类：
public class SingleOrder
{
public Order order { get; set; }
}
我可以看到所有数据都已正确反序列化，我可以在调试器中查看。但是，当我把它们放在文本块中时，没有任何表现。
1 个答案:
答案 0 :(得分：0)
问题发生在GridView。虽然我是从代码设置dataContext但是我没有添加GridView itemsSource。
只需添加即可解决问题：
ItemsSource="{Binding}"
