title: Why is my WPF textbox "kinda" readonly?
body: <p>I have a text box in WPF that is part of a datatemplate for a listbox. In that text box I can delete, backspace, spacebar, but I can NOT type in new words, letters or numbers. I CAN paste from notepad though.</p>
  
  <p>What am I missing here?  </p>
  
  <pre><code> &lt;ListBox Grid.Column="1"
           ItemsSource="{Binding Details}"
           VirtualizingStackPanel.VirtualizationMode="Recycling"
           HorizontalContentAlignment="Stretch" &gt;
              &lt;ListBox.Resources&gt;
                  &lt;DataTemplate DataType="{x:Type Entities:RADetailEntry}"&gt;
                      &lt;Grid&gt;
                          &lt;Grid.ColumnDefinitions&gt;
                              &lt;ColumnDefinition Width="Auto"/&gt;
                              &lt;ColumnDefinition Width="*"/&gt;
                          &lt;/Grid.ColumnDefinitions&gt;
  
                          &lt;ComboBox Grid.Column="0" /&gt;
                          &lt;TextBox Grid.Column="1" IsReadOnly="False" IsEnabled="True" 
                                   Text="{Binding Path=Description, Mode=TwoWay}" TextWrapping="Wrap"
                                   HorizontalAlignment="Stretch" VerticalAlignment="Stretch" TextAlignment="Left"  /&gt;
                      &lt;/Grid&gt;
                  &lt;/DataTemplate&gt;
              &lt;/ListBox.Resources&gt;
          &lt;/ListBox&gt;
