How to fill ListBox with data entries programatically in Silverlight?

Trying to fill the listbox programatically I have written the following code:

protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            TestDBContext context = new TestDBContext();
            context.Load(context.GetTaskQuery());

        var taskList = GetTasks();
        foreach (var t in taskList)
        {
            ListBoxTaskItems.Items.Add(t);

        }
    }

    private List<TaskItem> GetTasks()
    {
        var tasks = from t in context.Tasks
                    select new TaskItem(t);
        return tasks.ToList();
    }

The problem is that the code above alway returns an empty ListBox. Does any开发者_JAVA百科one know how to modify the existing code or another way to programatically fill the listbox with the data entries?

Edit #1: While debugging I've noticed that GetTasks() method is executed before context.GetTaskQuery() and I gues this is the reason for an empty ListBox. Nevertheless I don't know how to fix the code in order to populate the ListBox.

Thank you!

Somebody posted another solution, then for whatever reason deleted it, but that might work better. I just tried it in some code I'm working on and found it was faster:

Binding bind = new Binding();

bind.Source = GetTasks();

ListBoxTaskItems.SetBinding(ListBox.ItemsSourceProperty, bind);

(Substitute this for the foreach statement).

I'd try it like this inside your foreach statement:

ListBoxItem listBoxItem = new ListBoxItem();

listBoxItem.Content = t;

ListBoxTaskItems.Items.Add(listBoxItem);

I do something similar and it works when adding Grids to a ListBox, so as long as a TaskItem is something acceptable as Content that should do it.
