title: WPF FontFamily Format question
body: <p>I'm trying to set the selected value of my Font Family combobox, which has been populated with the following XAML:</p>
  
  <pre><code>&lt;ComboBox ItemsSource="{x:Static Fonts.SystemFontFamilies}" Name="cboFont"&gt;
      &lt;ComboBox.ItemsPanel&gt;
          &lt;ItemsPanelTemplate&gt;
              &lt;VirtualizingStackPanel MinWidth="256" /&gt;
          &lt;/ItemsPanelTemplate&gt;
      &lt;/ComboBox.ItemsPanel&gt;
      &lt;ComboBox.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;TextBlock Margin="2" Text="{Binding}" FontFamily="{Binding}"/&gt;
          &lt;/DataTemplate&gt;
      &lt;/ComboBox.ItemTemplate&gt;
  &lt;/ComboBox&gt;
  </code></pre>
  
  <p>The field I have to set the combobox to is a string, but that causes FormatExceptions. Can anyone quickly tell me what class the combobox will be expecting and also how to convert a string e.g. "Arial" to that format?</p>
