I am building a new DNN website with lots of forms built with Dynamic Forms. I have tried to add a new page with new form however adding the fields to the form I have noticed that under General Settings tab the Update Field/Exit button, Delete and Update Fields went missing. I tried to create a new event - such as submit the form, but it didn`t load the page and didn`t create the event either.

 

In the error log I found the following errors:

Error 1: When initially selecting New Event

Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'dnn_ctr1753_DynamicQuestions_UpdatePanelUpdateSettings'. If it is being updated dynamically then it must be inside another UpdatePanel.

 

Error 2: When changing the Event type

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
