How do I set the selected item of a listbox?
When I use SelectedValue, SelectedItem, SelectedIndex, it does nothing. When I use UpdateLayout( ) afterwards, it does nothing. ScrollIntoView( item ) does not appear to do anything.

This is the XAML code for my Listbox. I use a Setter to set the orientation of the listbox to horizontal

<ScrollViewer HorizontalScrollBarVisibility="Visible" Name="DetailedWebViewContainer" VerticalScrollBarVisibility="Disabled" Grid.Row="2">
        <ScrollViewer.Resources>
            <Style TargetType="ListBox">
                <Setter Property="ItemsPanel">
                    <Setter.Value>
                        <ItemsPanelTemplate>
                            <StackPanel Orientation="Horizontal"
                                        VerticalAlignment="Center"
                                        HorizontalAlignment="Center"/>
                        </ItemsPanelTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ScrollViewer.Resources>
        <ListBox Name="WebScrollView" SelectionMode="Multiple" >
            <ListBox.Items>
                <phone:WebBrowser Name="LeftBrowser" MinWidth="460" Height="1500" IsHitTestVisible="False" Margin="10, 0, 10, 0"/>
                <phone:WebBrowser Name="MiddleBrowser" MinWidth="460" Height="1500" IsHitTestVisible="False" Margin="10,0,10,10"/>
                <phone:WebBrowser Name="RightBrowser" MinWidth="460" Height="1500" IsHitTestVisible="False" Margin="10,0,10,0" />
            </ListBox.Items>                
        </ListBox>
    </ScrollViewer>

Am I missing something? Greetz GeekPeek

    This should work:

    <ListBox Name="WebScrollView" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto" SelectionMode="Multiple" >
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <VirtualizingStackPanel Orientation="Horizontal" />
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBox.Items>
        <phone:WebBrowser Name="LeftBrowser" MinWidth="460" Height="1500" IsHitTestVisible="False" Margin="10, 0, 10, 0"/>
        <phone:WebBrowser Name="MiddleBrowser" MinWidth="460" Height="1500" IsHitTestVisible="False" Margin="10,0,10,10"/>
        <phone:WebBrowser Name="RightBrowser" MinWidth="460" Height="1500" IsHitTestVisible="False" Margin="10,0,10,0" />
    </ListBox.Items>                
</ListBox>
