Jeff Handley - Silverlight 2 Gotcha - Tab Navigation in a Popup, Take 2

After I posted about how to regain tab navigation in a popup, Ian commented that the workaround had some flaws. First, he lost intellisense inside the <UserControl> and second, which is more painful, he could not refer to any controls inside the child <UserControl> from the page's code-behind.

Well, I found a more suitable workaround. Instead of using a <UserControl> to set the TabNagation, you can use a <ContentControl> instead. Here's the updated workaround code:

<UserControl x:Class="PopupTabbing.Page"

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 

  Width="400" Height="300">

  <Grid x:Name="LayoutRoot" Background="White">

  <Popup IsOpen="True">

  <Popup.Child>

  <ContentControl TabNavigation="Cycle">

  <StackPanel Width="150">

  <TextBlock Text="Username" />

  <TextBox x:Name="Username" />

  <TextBlock Text="Password" />

  <PasswordBox x:Name="Password" PasswordChanged="Password_PasswordChanged" />

  <Button Width="75" Content="Login" Click="Button_Click" />

  </StackPanel>

  </ContentControl>

  </Popup.Child>

  </Popup>

  </Grid>

</UserControl>

Thanks to Ian for pointing out the problems with the workaround!
