Hello CodeProject!

I''m learning and learning WPF and now I have digitalised my DVD collection and wanted to list them up in my ListBox. Clicking on them should give me the details of the dvd (master-detail-view).
Now my question is: How can I retreive the data bound to the selected ListBoxItem in Code-Behind? I think I have to use the SelectionChangedEvent, but how do I access the data and not the ListBoxItem?

Thanks!

推荐答案

好，我自己找到了解决方案:
我使用e.AddedItems [0]并将其投射.

OK, I found the solution myself:
I use e.AddedItems[0] and cast it.

private void MixControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
   //MessageBox.Show(e.AddedItems[0].ToString());
   Mix mix = (Mix)e.AddedItems[0];
}
