I can find documentation to validate a page within a custom Web Part which is part of Kentico's Page Wizard with the ValidateStepData method ( https://docs.kentico.com/display/K8/Connecting+web+parts+with+the+document+wizard ).
Is there also a way to validate step data when you are using ASP.Net usercontrols (system.web.ui.usercontrol / ascx ) on the page wich are imported with the Usercontrol Web Part? So you want go further unless the requirements defined in the usercontrol are ok?
Hello,
If the custom control inherit from CMSCheckoutWebPart I think it will be achievable. Try this.
