Question

为了填补清单框表,我撰写了以下代码:

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();
    }

问题在于,上岸的代码是空洞的Box。是否有任何人知道如何修改现行法典,或以另一种方式以方案方式用数据条目填写清单箱?

谢谢!

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);

(附上声明)。

我在你的发言中试图这样做:

ListBoxItem listBoxItem = new ListBoxItem();

listBoxItem.Content = t;

ListBoxTaskItems.Items.Add(listBoxItem);

我也做了类似的事情,在把Grids添入一个名单Box时,只要一个任务项目与应该做的内容一样是可以接受的。
