title: ComboBox KeyValuePair Binding WPF - Display Member
body: <p>i got a quick question about binding the <code>DisplayMember</code> of my <code>ComboBox</code>.
  I have a list with a <code>KeyValuePair</code> for example:</p>
  <p>1, Value1;<br />
  2, Value2;<br />
  3, Value3;</p>
  <p>My <code>SelectedValuePath</code> is set to <code>Key</code> which is in my example &quot;1&quot;.
  Now i want my <code>DisplayMemberPath</code> to show &quot;<code>Key</code> - <code>Value</code>&quot; so for example the Textbox should show &quot;1 - Value1&quot;.
  Is that possible?
  Thank's in advance!</p>
