Silverlight Tabbing issue

This code tabs perfectly in WPF.  If will not tab in the order of 0, 1, 2, 3 in Silverlight.  Can anyone explain why?  Is this a silverlight bug?  Does anyone know how to fix it.

The problem arose because the TextBoxes with the values 0 & 2 were in different containers to the TextBoxes with the values 1 & 3.

The attached code snippet solves the problem but after the user Tabs past '3' then Silverlight loses focus and it will Tab to the browser.
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
        </Grid.RowDefinitions>
 
        <Grid Grid.Row="0" Width="100" Height="100">
            <Grid.RowDefinitions>
                <RowDefinition></RowDefinition>
                <RowDefinition></RowDefinition>
                <RowDefinition></RowDefinition>
                <RowDefinition></RowDefinition>
            </Grid.RowDefinitions>
 
            <TextBox Grid.Row="0" TabIndex="0" Width="50" Text="0"/>
            <TextBox Grid.Row="1" TabIndex="2" Width="50" Text="2"/>
            <TextBox Grid.Row="2" TabIndex="1" Width="50" Text="1"/>
            <TextBox Grid.Row="3" TabIndex="3" Width="50" Text="3"/>
        </Grid>
 
    </Grid>

Right.  This is what really sucks about silverlight tabbing.  You have to write your containers around tabbing!  How rediculous is that?

It seems to be the same in Windows Forms but not WPF.

You could probably handle this yourself on the by setting the focus of the relevant control on the KeyDown event of the TexBox.

Just create a KeyDown Handler for all textboxes and set the focus based on CType(Sender, TextBox).TabIndex

Please see the code snippet below (For this to work you need to name your textboxes TextBox1, TextBox2, TextBox3 and TextBox4

Tom
    Private Sub TextBoxes_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles TextBox1.KeyDown, TextBox2.KeyDown, TextBox3.KeyDown, TextBox4.KeyDown
        If e.Key = Key.Tab Then
            e.Handled = True
            Select Case CType(sender, TextBox).TabIndex
                Case 0
                    Me.TextBox3.Focus()
                Case 1
                    Me.TextBox2.Focus()
                Case 2
                    Me.TextBox4.Focus()
                Case 3
                    Me.TextBox1.Focus()
            End Select
        End If
    End Sub
