Multiselect ListBox
提问by ni3a
I'm having trouble in multiple items selection in an ListBox.
我在 ListBox 中选择多个项目时遇到问题。
I've tried deriving new control from Selector and writing ListBox helper class which did not work (as expected).
我试过从 Selector 派生新控件并编写 ListBox helper 类，但它不起作用（如预期）。
The issue with Selector class is, it does not expose SelectedItems and it's hell to bind the property and manipulate it with selection changed event.
Selector 类的问题是，它不公开 SelectedItems 并且绑定属性并使用选择更改事件对其进行操作是地狱。
The issue with ListBox Helper class is, I'm getting the required data on multiple selection but it never hits the bound property.
ListBox Helper 类的问题是，我正在获取多项选择所需的数据，但它从未命中绑定属性。
Does anybody know a better way to implement multiselect listbox?
有人知道实现多选列表框的更好方法吗？
Thanks in advance...
提前致谢...

The ListBoxhas multiple selection already implemented. Just change SelectionModeproperty to Multiple or Extened.
该列表框具有多重选择已经实施。只需将SelectionMode属性更改为 Multiple 或 Extened。
You can use SelectedItemsproperty to get all the selected items afterwards.
您可以使用SelectedItems属性来获取所有选定的项目。
