title: WPF ComboBox ItemsSource Binding on Dictionary not working
body: <p>I'm having trouble with this binding and can't seem to get it working.</p>
  
  <p>xaml</p>
  
  <pre><code>&lt;telerik:RadComboBox
      ItemsSource="{Binding ReminderTimes.Keys}"
      SelectedItem="{Binding SelectedReminderTime, 
                             UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"
  /&gt;
  </code></pre>
  
  <p>c#</p>
  
  <pre><code> public Dictionary&lt;string, int&gt; ReminderTimes
   {
       get { return ReminderTimesManager.GetReminderTimes(); }
   }
  </code></pre>
  
  <p>I did put a breakpoint in the properties get and it's not getting hit ever and I have no idea why. Any input is appreciated. </p>
