A try in WPK (one way and only once)

The best I found in WPK seems to be the the following:

ipmo WPK            
            
$option = "To File" # this value might be prompted by the user            
             
             
New-StackPanel {            
    New-RadioButton -Content "To Text" -GroupName Results -IsChecked $True -On_Click {             
        $Resource.Result = "To Text"             
        $info = $window | Get-ChildControl info            
        $info.text = $Resource.Result            
        $env:WPKResult = $Resource.Result            
        }            
    New-RadioButton -Content "To Grid" -GroupName Results -On_Click {              
        $Resource.Result = "To Grid"             
        $info = $window | Get-ChildControl info            
        $info.text = $Resource.Result            
        $env:WPKResult = $Resource.Result            
        }            
    New-RadioButton -Content "To File" -GroupName Results -On_Click {              
        $Resource.Result = "To File"             
        $info = $window | Get-ChildControl info            
        $info.text = $Resource.Result            
        $env:WPKResult = $Resource.Result            
    }            
    New-RadioButton -Content "To CSV" -GroupName Results -On_Click {              
        $Resource.Result = "To CSV"             
        $info = $window | Get-ChildControl info            
        $info.text = $Resource.Result            
        $env:WPKResult = $Resource.Result            
    }            
    New-textBox -Name info             
    } -On_Loaded {            
            $info = $window | Get-ChildControl info            
            $info.text = $Resource.Result            
    }-asjob -resource @{Result = $option}            
            

I can modify the value within GUI and query it outside

$env:WPKResult

I misuse the processes environment, which is shared between the runspaces. Hmm better than pidgeon carrying USB sticks, but it is restricted to strings.

I guess I have to really dive into PowerBoots  (and that is the polite version ;-) of my opinion about WPK)

Have some fun trying to find further work arounds.
