Validate Textbox with Regex

I,m having trouble getting this validation to work on a textbox. I want to validate a valid version format is used.

 New-UDTextbox -Id "AppVersion" -Label "application Version" -OnValidate {
                    if ($EventData -match '^\d+(\.\d+){1,3}$' ) {
                        New-UDValidationResult -Valid
                    }
                    else {
                        New-UDValidationResult -ValidationError 'must be a version'
                    }
                }

This pattern works in PowerShell but when I enter any value into the textbox, I get the validation error. I’m not sure what I am missing.

Which version of PSU?

I never tried that before, but do not seem to be able to get even the example working.

I tried this and it looks like, if you enter something like “1.2.3” into a textbox, it gets cast to “datetime” which cannot match your regex:

New-UDTextBox -Id "AppVersion" -Label "application Version" -OnChange {
    Show-UDToast -Message "App Version: $EventData" -Duration 10000
    Show-UDToast -Message "EventdataType: $($EventData.GetType())" -Duration 10000
} -OnValidate {
    if($EventData -match "^\d+(\.\d+){1,3}$") {
        New-UDValidationResult -Valid
    } else {
        New-UDValidationResult -ValidationError "App Version needs to match '^\d+(\.\d+){1,3}$'"
    }
}

Interesting! That is strange. I think I solved this by not using $EventData but instead using Get-UDElement.

New-UDTextbox -Id "AppVersion" -Label "application Version" -OnValidate {
                    $inputText = (Get-UDElement -Id 'AppVersion').Value
                    if ($inputText -cmatch '^\d+(\.\d+){1,3}$' ) {
                        New-UDValidationResult -Valid
                    }
                    else {
                        New-UDValidationResult -ValidationError 'must be a version'
                    }
                }
