데이터 바인딩이 작동하지 않습니다. XAML C# WPF

Question

WPF 폼이 있고 UI의 desagialized json 데이터를 DataGrid에 바인딩하려고합니다. 하지만 여기에 UI에서 데이터 그리드의 값을 볼 수 없습니다.

JSON response: 
Firstly, my json response is in the below format: 
{ 
    "results": 
     [ 
      {"type": "upload", "status": "new","data": {"uuid":"f7e98"},"device_id": "123"}, 
      {"type": "upload", "status": "new","data": {"uuid":"f8fc1"},"device_id": "456"}, 
      {"type": "upload", "status": "new","data": {"uuid":"fgff1"},"device_id": "678"}, 
      {"type": "upload", "status": "new","data": {"uuid":"yuki1"},"device_id": "786"}, 
      {"type": "upload", "status": "new","data": {"uuid":"rtyi1"},"device_id": "654"} 
     ] 
} 

클래스 : 여기

public class UploadStatusList 
{ 
    public List<UploadStatus> results; 
} 
public class UploadStatus 
{ 
    public string type {get;set;} 
    public string status {get;set;} 
    public string device_id {get;set;} 
    public Data data {get;set;} 
} 
public class Data 
{ 
    public string uuid {get;set;} 
} 

내 홈페이지 window.xaml.cs
MainWindow.xaml.cs를하다 : 아래

public partial class MainWindow : Window 
{ 
    // Dependency Property 
    public static readonly DependencyProperty actionListProperty = 
     DependencyProperty.Register("actionList", typeof(ObservableCollection<UploadStatusList>), 
      typeof(MainWindow), new FrameworkPropertyMetadata(null)); 

    // .NET Property wrapper 
    public ObservableCollection<UploadStatusList> actionList 
    { 
     get { return (ObservableCollection<UploadStatusList>)GetValue(actionListProperty); } 
     set { SetValue(actionListProperty, value); } 
    } 


    public MainWindow() 
    { 
     InitializeComponent(); 
     //Code Block for httpwebRequest here 
     //JSON Response String 
     string json = stringbuilder.ToString(); 

     //Newtonsoft.Json.JsonConvert.Deserialize<UploadStatusList>(json) returns null for me here,so using Javascript serializer. No idea why !? 
     UploadStatusList list = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<UploadStatusList>(json); 
     foreach (var item in list.results) 
     { 
      Debug.Print("id: {0}, name: {1}", item.status, item.device_id); 
     } 
    } 
}  

내 기본 창입니다 .XAML ... xaml을 처음 접했을 때 내가 무엇이든 놓친다면 확신 할 수 없다.,210 MainWindow.xaml :

<TabItem x:Name="UploadList" Header="Upload List" HorizontalAlignment="Left" Width="77" Margin="-2,-2,0,2"> 
       <Grid Margin="0,0,0,0"> 
        <Grid.ColumnDefinitions> 
         <ColumnDefinition Width="124*"/> 
         <ColumnDefinition Width="107*"/> 
        </Grid.ColumnDefinitions> 


        <Button x:Name="Button" Content="Refresh" Margin="14,40,0,361" HorizontalAlignment="Left" Width="120" Click="Button_Click"/> 

        <DataGrid Margin="14,79,10,58" x:Name="Access_DataGrid" IsReadOnly="True" ItemsSource="{Binding actionList.results}" IsSynchronizedWithCurrentItem="True" AutoGenerateColumns="False"> 
      <DataGrid.Columns> 
       <DataGridTextColumn Header="status" Binding="{Binding status}" /> 
       <DataGridTextColumn Header="device id" Binding="{Binding device_id}" /> 
       <DataGridTextColumn Header="type" Binding="{Binding type}" /> 
      </DataGrid.Columns> 

        </DataGrid> 
       </Grid> 
      </TabItem>

당신은 단지 모든 권리를 수행하지만 ItemSource에 바인딩에 ElemmentName을 추가하거나의 DataContext를 사용합니다.

<Window x:Name="mainWindow".....> 
     <... ItemsSource="{Binding actionList.results, ElementName=mainWindow}".....
