How Do I Force A Full Form Post Back on DNN 4.7

I have a special situation where I have a client (who’s web site use to be DNN 2.X) needs to have the ability to do post-backs.

This is because we have a small input box on the webpage where a user can submit hidden input to another DNN page with an IFRAME that links to an HTML page that accepts the submitted information from the simple input boxes.

My problem is that I have to carry over this feature from DNN 2.X over to a new site that is 4.7

And because DNN 4.7 is Ajaxing the entire page, I cannot do a traditional Form post-back to a HTML/ASP page inside an DNN Iframe. I get an error that reads

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Any suggestions on how to submit this info from my DNN Page to an HTML page inside of a DNN DNN 4.7 Iframe?

Not sure i understand what you want you want info from the hosting page (the one that has the iframe) to put info into the html page in the iframe and then force that page to submit itself?

I think you are looking at a javascript solution there

not really sure but maybe a on click event on the hosting page submit button and then js to submit the inside form

Does that help or am i off base?

Thanks...

I've also just been informed by a Robert Chumley (while discussing this issue on another DNN formum) that DNN has changed the way forms are submitted. And a patch is being written. This patch is to be posted shortly.

I am very curious which previous version of 4.x would remain unchanged?
