We need help regarding visibility and dynamic calculated expressions inside new and edit forms (not the standard calculated fields from SharePoint). Until now we used mostly Ardevia Rich Forms for building custom forms.
We are now working on a Visual Studio project and we are building a list with custom new,edit and display forms. We know how to sort the fields and make changes in the layout. Now we are going into the next phase: visibility and calculated expressions inside new and edit form. Our main problem is to make the same without third party tools.
Are there somewhere good examples how to make these kind of expressions?
