Adding a text or command after a button click - powershell

Question

Need advice on adding a text in let's say Text_Status after hitting a button.
How can I also automatically continue the command after a restart to let's say Button_clearTPM, then going to Button_enableTPM, then going to Button_initializeTPM?
Here is my XAML:
[xml]$xaml = #'
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="TPM Script" Height="482" Width="479" Background="White">
<Grid Height="375" Width="382">
<Button Content="Clear TPM" Height="55" HorizontalAlignment="Left" Margin="230,30,0,0" Name="Button_clearTPM" VerticalAlignment="Top" Width="140"/>
<Button Content="Enable TPM" Height="55" HorizontalAlignment="Left" Margin="230,0,0,220" Name="Button_enableTPM" VerticalAlignment="Bottom" Width="140"/>
<Button Content="Initialize TPM" Height="55" HorizontalAlignment="Left" Margin="230,169,0,0" Name="Button_initializeTPM" VerticalAlignment="Top" Width="140"/>
<Label Content="Enter Workstation ID: " Height="23" HorizontalAlignment="Left" Margin="31,45,0,0" Name="Label_1" VerticalAlignment="Top" Width="133"/>
<TextBox Height="38" HorizontalAlignment="Left" Margin="31,74,0,0" Name="Text_WSID" VerticalAlignment="Top" Width="171" />
<TextBox Height="114" HorizontalAlignment="Left" Margin="31,241,0,0" Name="Text_Status" VerticalAlignment="Top" Width="329" />
</Grid>
</Window>
'#
[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')
$reader=(New-Object System.Xml.XmlNodeReader $xaml)
try
{
$Form=[Windows.Markup.XamlReader]::Load( $reader )
}
catch
{
Write-Host "Unable to load Windows.Markup.XamlReader. Some possible causes for this problem include: .NET Framework is missing PowerShell must be launched with PowerShell -sta, invalid XAML code was encountered."t
}
cls
#First Button
$clearTPM = $Form.FindName('Button_clearTPM')
$clearTPM.Add_Click({ Write-Host "Clear TPM clicked" -ForegroundColor Cyan})
#Second Button
$enableTPM = $Form.FindName('Button_enableTPM')
$enableTPM.Add_Click({ Write-Host "Enable TPM clicked" -ForegroundColor Cyan})
#Third Button
$initializeTPM = $Form.FindName('Button_initializeTPM')
$initializeTPM.Add_Click({ Write-Host "Initialize TPM clicked" -ForegroundColor Cyan})
$Form.ShowDialog() | out-null

The problem is your script doesn't know what your label is.
So you have to make it accessible by making it into a variable.
Then, you can assign whatever text you want via .Content.
So :
[xml]$xaml = #'
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="TPM Script" Height="482" Width="479" Background="White">
<Grid Height="375" Width="382">
<Button Content="Clear TPM" Height="55" HorizontalAlignment="Left" Margin="230,30,0,0" Name="Button_clearTPM" VerticalAlignment="Top" Width="140"/>
<Button Content="Enable TPM" Height="55" HorizontalAlignment="Left" Margin="230,0,0,220" Name="Button_enableTPM" VerticalAlignment="Bottom" Width="140"/>
<Button Content="Initialize TPM" Height="55" HorizontalAlignment="Left" Margin="230,169,0,0" Name="Button_initializeTPM" VerticalAlignment="Top" Width="140"/>
<Label Content="Enter Workstation ID: " Height="23" HorizontalAlignment="Left" Margin="31,45,0,0" Name="Label_1" VerticalAlignment="Top" Width="133"/>
<TextBox Height="38" HorizontalAlignment="Left" Margin="31,74,0,0" Name="Text_WSID" VerticalAlignment="Top" Width="171" />
<TextBox Height="114" HorizontalAlignment="Left" Margin="31,241,0,0" Name="Text_Status" VerticalAlignment="Top" Width="329" />
</Grid>
</Window>
'#
[void][System.Reflection.Assembly]::LoadWithPartialName('presentationframework')
$reader=(New-Object System.Xml.XmlNodeReader $xaml)
try
{
$Form=[Windows.Markup.XamlReader]::Load( $reader )
}
catch
{
Write-Host "Unable to load Windows.Markup.XamlReader. Some possible causes for this problem include: .NET Framework is missing PowerShell must be launched with PowerShell -sta, invalid XAML code was encountered."t
}
## THIS IS WHERE MAGIC HAPPENS
$xaml.SelectNodes("//*[#Name]") | %{Set-Variable -Name "$($_.Name)" -Value $Form.FindName($_.Name)} # find all names and make them accessible via a variable
#First Button
$clearTPM = $Form.FindName('Button_clearTPM')
$clearTPM.Add_Click({
Write-Host "Clear TPM clicked" -ForegroundColor Cyan
$label_1.content = "Clear TPM clicked"
})
#Second Button
$enableTPM = $Form.FindName('Button_enableTPM')
$enableTPM.Add_Click({ Write-Host "Enable TPM clicked" -ForegroundColor Cyan})
#Third Button
$initializeTPM = $Form.FindName('Button_initializeTPM')
$initializeTPM.Add_Click({ Write-Host "Initialize TPM clicked" -ForegroundColor Cyan})
$Form.ShowDialog() | out-null
