I'm searching for a way to display the submitted form data on the next page - Using "Umbraco forms" in Umbraco 7.6.3.

I've tried the available methods on https://our.umbraco.org/documentation/Products/UmbracoForms/Developer/Working-With-Data/ but most of the methods returns nothing or throws the "There is already an open DataReader" error.

  • The DataReader issue is probably because you're trying to access the database while it's being read somewhere else. Checkout to fix this issue: https://stackoverflow.com/a/21131596/2963111 – harvzor Jun 16 '17 at 14:10

I would recommend creating a custom workflow which sets a variable which stores the form submission ID to the users session.

Then, when the user checks out the next page, you can query for that submission and display what was posted.

Or you could use Form Editor instead. It's got this among other features built-in and documented - see these tutorials.
