UI 컨트롤 업데이트 wpf 백그라운드 스레드

Question

새로운 리본 탭 및 새 자식 컨트롤을 Grid에 추가하는 작업 응용 프로그램이 있습니다.

나는 등 데이터베이스에서 데이터를 수집하는 동안,

을 취할 수있는 자식 컨트롤로 백그라운드 스레드에이 작업을 넣어 싶습니다 내가 가지고 지금까지 다음 코드를

Ribbon Ribbon_Main = new Ribbon(); 
Grid Grid_Main = new Grid(); 

Thread newthread2 = new Thread(new ThreadStart(delegate { Graphing_Template.add_report(); })); 
newthread2.SetApartmentState(ApartmentState.STA); //Is this required? 
newthread2.Start(); 


Class Graphing_Template() 
{ 
    static void add_report() 
    { 
    RibbonTab rt1 = new RibbonTab(); 
    MainWindow.Ribbon_Main.Items.Add(rt1); 
    // Create control with information from Database, etc. 
    // add control to MainWindow.Grid_Main 
    } 
} 

새 보고서 컨트롤을 백그라운드에서 만든 다음 준비가되면 기본 UI에 추가하고 싶습니다.

내가 갔다 솔루션은 다음과 같습니다 당신이 UI 스레드에서가 아니라면

일반적으로

 BackgroundWorker worker = new BackgroundWorker(); 
    worker.DoWork += delegate(object s, DoWorkEventArgs args) 
      { 
       DataTable dt1 = new DataTable(); 
       ---- Fill DataTable with 
       args.Result = datagrid_adventureworks_DT(); 
      }; 

worker.RunWorkerCompleted += delegate(object s, RunWorkerCompletedEventArgs args) 
      { 
       DataTable dt1 = (DataTable)args.Result; 
       Datagrid_Main.ItemsSource = dt1.AsDataView(); 
      };

    private async void Test4() 
    { //if you are using .Net 4.5 you can use the Async keyword 
     //I _think_ any computation in your async method runs on the UI thread, 
     //so don't use this for ray tracing,
