Synchronice a DataGrid with a list by a Thread (backgroundWorker). WPF C#

Question

I´m tring to link data from a List to a DataGrid, but when I start the object BackgroundWorker, the main thread has been loaded (with a empty List) before the BackgroundWorker fill the List. How can update or something in order to load the data from the BackgroundWorker?

Constructor of MainWindow, here I declare the BackgroundWorker

```
  public MainWindow()
    {
        InitializeComponent();
        backgroundWorker = new BackgroundWorker();            
    }   

A methot to call the function backgroundWorker_DoWork

```       
  private void referenceBtn_Click(object sender, RoutedEventArgs e)
     {
        backgroundWorker.DoWork += backgroundWorker_DoWork;
        backgroundWorker.RunWorkerAsync();

    }  

If the operation is correct I get a lis of object(ApiProduct) and i save them. I try to link by this method, but it´s static. ```

  public static void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
    {
        if (textinPut != null && textinPut.Length >= 3)
        {
            ApiConector apiConector = new ApiConector();
            UpdatedListProducts = apiConector.getProductList(textinPut, 2);
            //dgProducto.ItemsSource = UpdatedListProducts;
        }
    } 

```

 public static List<ApiProduct> UpdatedListProducts
    {
        get { return apiProductsStatic.ToList(); }
        set
        {
            apiProductsStatic = value;
        }
    } 

```

Answer 1

I don't see any need for static members, every window should have its own Data, and its own event handlers, so you should make them non-static

UpdatedListProducts from name show that the list is regularly in change so is better to make it of type ObservableCollection<ApiProduct> instead of List<ApiProduct> to notify the UI if items add or deleted and reflect that change in UI

here is a good article on how to make UI Responding to changes with an intro to The ObservableCollection and the INotifyPropertyChanged interface.
