WPF and powershell , how do you run code without user interaction?

Question

I am using the code below to start a form but when the form opens i would like to start off the code processing without the need for the user to press a button again.
I would like to have some test-connection been done when the form starts below there is some striped dwon code example.
The $textbox.text = "Could not connect to remote pc"  show be run when the form is displayed by  $Window.ShowDialog()
How do i do this, I tryed adding it to the show dialog but that does not take input. Right now afther calling  $Window.ShowDialog() the form pauses and waits for input?
$reader=(New-Object System.Xml.XmlNodeReader $xaml)
$Window=[Windows.Markup.XamlReader]::Load( $reader )
#Connect to Controls
$button1 = $Window.FindName('button1')
$textbox = $Window.FindName('textbox1')
 #Events
$button1.Add_Click({
    $services = Get-Service
    $listbox.ItemsSource = $services
 $Window.ShowDialog() | Out-Null
$textbox.text = "Could not connect to remote pc"

Hello Martijn,
For details about how to write this script, I think you'd better consult PowerShell related forum instead of here. We can only share the WPF related scrnario.
In wpf, you can just add your code from button click event to the following event:
Window_Loaded event
https://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.loaded(v=vs.110).aspx
In VS its here:
private void Window_Loaded(object sender, RoutedEventArgs e)
//AdornerLayer.GetAdornerLayer(myTextBox).Add(new SimpleCircleAdorner(myTextBox));
Or you could put your code in:
public MainWindow()
InitializeComponent();
//add your code here.
In this way I think you do not need to add that button event. However we do not know how to write it with PowerShell scripts, this is out of our scope here.
Best regards,
Barry
