Umbraco Forms Custom Workflows Tip: How to redirect to another page other than the default thank you page after submitting an Umbraco Forms form

Umbraco Forms is an add-on for Umbraco CMS that allows you to easily create forms and link them to your content pages. After the form submissions, you can redirect your web users to a "thank you" page using the built-in "Submit message / Go to page" workflow. However, what if you want to redirect to a page dynamically based on the data submitted by the end user?

Custom workflow to redirect 

One of the best solutions is to create a custom Umbraco Forms workflow based on requirements. 

For Umbraco v13+ websites, rather than using the HttpContext to redirect, which won't work out of the box for your custom workflow, you should use the WorkflowExecutionContext to set the GoToPageOnSubmit property of your form, like this.

context.Form.GoToPageOnSubmit = goToPage.Id;

It is as simple as this. You can now do your tests and dynamically redirect your users to the next page after the form submissions.
