WP LongListMultiSelector控件Bug,单项删除第五个时候报错

WP LongListMultiSelector控件Bug,单项删除第五个时候报错。MSDN找了下发现也有人报告过该问题，貌似目前官方还未给出解决方案。MSDN帖子其中一些解决方案重新继承控件，重载某个方法。

个人解决方案：

void OnDeleteClick(object sender, EventArgs e)

{

try

{

if (MessageBox.Show("删除选中?", AntiTheft.Resources.AppResources.SoftName, MessageBoxButton.OKCancel) == MessageBoxResult.OK)

{

//由于LongListMultiSelector控件存在bug,单项删除第五个时候会报错。所以下面注释方法暂不用

//while (PushList.SelectedItems.Count > 0)

//{

// UserLoginStorage.PushList.Remove(PushList.SelectedItems[0] as Mode.Push);

//}

//改用把控件数据源抽出筛选完（删除后）重新赋值给控件数据源，最后再同步到绑定到控件的数据源（PushList为LongListMultiSelector控件ID）

var p = PushList.ItemsSource as ObservableCollection<Mode.Push>;

//从数据源筛选并剔除选中项

PushList.ItemsSource = new ObservableCollection<Mode.Push>(from n in p

where PushList.SelectedItems.Contains(n) == false

select n);

UserLoginStorage.PushList = PushList.ItemsSource as ObservableCollection<Mode.Push>;

ResetItemsList();

}

}

catch (Exception)

{

MessageBox.Show("删除失败");

}

}
