Let's say I have a simple button and an input field (non epi-property). I want to read the value from the input filed and update the property Title when in "on-page-edit-mode'. Is this possible and how?
Not sure how to do this with Dojo, but you have the Html.FullRefreshPropertiesMetaData() that does something similar: http://world.episerver.com/Documentation/Items/Developers-Guide/EPiServer-CMS/75/Content/Edit-hints-in-MVC/#FullRefreshProperties.
I will look into it.
