在Silverlight中从列表框拖放到列表框

Question

I am using a listbox to bind the data coming from the database, once the binding is done there is another listbox where i have to drag and drop the contents of the first listbox. I am able to drag and drop it but nothing is visible in the 2nd listbox(but the content is moving from the 1st to 2nd listbox). The same thing i tried by hardcoding the items in the 1st listbox and everything worked fine. If anybody has experienced similar kind of problem, please help.

Answer 1

您将必须处理第二个列表框的ondrop事件，并且必须更新在drop事件中绑定到第二个列表框的集合。

Answer 2

Make sure you're using ObservableCollection when dragging and dropping between sources. If you used List, then the ListBoxes will not be notified of a change in the collection.
