推荐答案
Your first problem is that you have nothing to bind to. What you should be doing is usingListBoxinstead of StackPanel. Then you can Bind to the SelectedItem property. If you do not like the container for the defaultListBox, then you override theItemsPanel, and you can also override the defaultItemTemplate:

<listbox name="ListBoxAvailablePickedBrokers">

BorderThickness="0"
