Thank you so much. That worked!!!!!!!!!!!!

Hi,

I think that maybe you could try the following hacky solution, note that for all elements for which you defined Name/x:Name properties in XAML, a field is automatically defined in the corresponding .xaml.g.cs file (you can open it by choosing project 'see all files' option and going to the obj directory):

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

        <Grid.RowDefinitions>

            <RowDefinition/>

            <RowDefinition Height="Auto"/>

        </Grid.RowDefinitions>

        <ig:XamOutlookBar x:Name="OutlookBar1" HorizontalAlignment="Left">

            <ig:OutlookBarGroup>

                <Grid x:Name="Grid1">

                    <Grid.RowDefinitions>

                        <RowDefinition/>

                        <RowDefinition/>

                    </Grid.RowDefinitions>

                    <ig:XamTree x:Name="Tree1">

                        <ig:XamTreeItem x:Name="TreeItem1" Header="Level1Node1"/>

                        <ig:XamTreeItem Header="Level1Node2"/>

                    </ig:XamTree>

                    <Ellipse x:Name="Ellipse1" Grid.Row="1" Height="200" Width="100" Fill="Red"/>

                </Grid>

            </ig:OutlookBarGroup>

        </ig:XamOutlookBar>

        <Button Grid.Row="1" Content="Stretch Ellipse" Click="Button_Click" Margin="10"/>

    </Grid>

    public partial class OutlookBar : UserControl

    {

        public OutlookBar()

        {

            InitializeComponent();

            this.OutlookBar1.LayoutUpdated += this.OutlookBar1_LayoutUpdated;

        }

        void OutlookBar1_LayoutUpdated(object sender, EventArgs e)

        {

            this.Tree1 = ((XamTree)(this.FindName("Tree1")));

            this.TreeItem1 = ((XamTreeItem)(this.FindName("TreeItem1")));

            this.Ellipse1 = ((Ellipse)(this.FindName("Ellipse1")));

            this.OutlookBar1.LayoutUpdated -= this.OutlookBar1_LayoutUpdated;

        }

        private void Button_Click(object sender, RoutedEventArgs e)

        {

            this.Ellipse1.Width = 200;

        }

    }

HTH,

Thanks for your reply.

But using that approach I get the first control, but I want something like 3rd control from the group.

Thanks
