Hi, after working on some small projects involving the further processing of outputs into variables, I wanted to share my experiences. I would like to use this thread as a basis so that everyone can make their experiences visible to others. It can sometimes be a bit tricky to apply the correct variable.

Working with New-UDForm: $formResult= ($EventData.form1Textbox)

    New-UDForm -Id 'form1' -Content {
        New-UDTextbox -Id 'form1Textbox' -HelperText 'Some input value!' -Autofocus
        } -OnSubmit {
        $formResult= ($EventData.form1Textbox)
        Show-UDToast -Message "$formResult" -Duration 6000
        }

Working with New-UDUpload: $Session:CSV = Import-CSV $Body.FileName

        New-UDGrid -Item -ExtraSmallSize 2 -Content {
            New-UDUpload -Text 'Upload CSV' -Icon (new-UDIcon -Icon file-import -Size lg) -OnUpload {
                $Session:CSV = Import-CSV $Body.FileName -Delimiter ";"
                Sync-UDElement -Id 'CSV'
            } -HideUploadedFileName
        }

Working with Invoke-PSUScript (IIS): $Session:Testresult = invoke-PSUScript

It is important that the mentioned script includes a return $variable , so that the output can be further processed in the Invoke-PSUScript .

            New-UDButton -Id 'btnRunScript' -Text "Get value" -OnClick {
                $Session:Testresult = invoke-PSUScript -name "Test.ps1" -ComputerName 'PSU hostname' -AppToken "Apptokenkey" -Wait
                Sync-UDElement -Id 'testTable'
            } -ShowLoading
