        </Grid.RowDefinitions>
            <Button Name="Button1" Content="ClickMe" Width="61" Height="20" Margin="12,12,0,0" HorizontalAlignment="Left" VerticalAlignment="Top"></Button>
        <TabControl Name="tabChildContainer" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" Grid.Row="1"></TabControl>

    </Grid>
</Window>
"@
[xml]$UserControlXAML = @"
<UserControl 
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    </Grid>
</UserControl>

"@

$MainReader = New-Object System.Xml.XmlNodeReader $MainXAML
$Window_Main= [Windows.Markup.XamlReader]::Load($MainReader)

$UC_Reader = New-Object System.Xml.XmlNodeReader $UserControlXAML
$Window_UC= [Windows.Markup.XamlReader]::Load($UC_Reader)


$MainXAML.SelectNodes("//*[@Name]") | %{ Set-Variable -Name ("WPF_Main_"+$_.Name) -Value $Window_Main.FindName($_.Name) -Scope "Script" }
$UserControlXAML.SelectNodes("//*[@Name]") | %{ Set-Variable -Name ("WPF_UC_"+$_.Name) -Value $Window_UC.FindName($_.Name) -Scope "Script" }
$script:WPF_Main_button1.Add_Click(
{
    Write-Host -ForegroundColor Green "I am in the click event."
    $TabItem1 = New-Object System.Windows.Controls.TabItem
    $TabItem1.Header = "Eureka"
    $TabItem1.AddChild($WPF_UC_button1)
    $WPF_Main_tabChildContainer.Items.Add($TabItem1)
})
$Window_Main.ShowDialog()
