What you could do I think have your own render template of xform. By doing this, you could read from setting and decided what to render. You could refer to following blog http://www.eyecatch.no/blog/2013/09/full-customization-of-xforms-with-episerver-7-and-mvc/.
I think that easy way to go.
I am very new to EPiServer development, so this may be a rookie question, but here goes!
In EPiServer 7.5 I have a block containing an XFrom for setting user preferences. The form consists of 1 textbox (email address) and 4 checkboxes for mailing preferences. When the form is created the controller reads the current preference settings from the database, using an ID paramater passed in the URL, and I then want to pre-populate the form with these details.
I can get the email address textbox populated using the following code:
However, I can't seem to use this for setting the checked value of a checkbox. Has anyone had any experiance in this kind of thing who could point me in the right direction?
