title: Data Binding Combobox to Textbox
body: <p>I've been working with my program about books.It works like putting some information about the book and when done it is added in the list.
  but when I pick a content in the combobox ( example 03 ) it will bind into my textbox as " System.Windows.Controls.ComboBoxItem: 03 " 
  I just cant figure out how to make it 3 and remove the system.windows.etc 
  Here is my code btw</p>
  
  <pre><code>&lt;TextBox Grid.Row="5" Grid.Column="3" Name="monthp" Margin="1" Text="{Binding book_datepublishedmonth,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" /&gt;  
  &lt;ComboBox Grid.Row="4" Grid.Column="3" Name="monthcombo" Margin="1" SelectedItem="{Binding Text , ElementName=monthp }"  &gt;
  &lt;ComboBoxItem Content="01" /&gt;
  &lt;ComboBoxItem Content="02" /&gt; 
  &lt;ComboBoxItem Content="03" /&gt;
  &lt;/ComboBox&gt;
  </code></pre>
  
  <p>When I run my code i really dont know why it has System.Windows.Controls.ComboBoxItem in the textbox. Is there something im missing? </p>
  
  <p>Thanks in advance for pointing it out :)</p>
