My guess is that you aremissing the views for the forms somehow. You should have a package for forms in you modules folder of your website. In that folder you sould have a zip that contains all views. Also you will have a config-file in the episerver.forms catalog. This config-file has a setting for the path were the views is supposed to be located. This Thread has the same explanation as I am trying to tell you :)
The partial view 'FormContainerBlock' was not found or no view engine supports the searched locations.
Had to create a new View folder and point the Forms.config value to it: formElementViewsFolder="~/Views/Shared/Blocks/Forms"
Thanks Eric for your help.
Actually I got it. I was forget to register the content area for epiform as implimented in alloy site. Issue has been resloved now.
I am new in EPiforms. I have installed the form by nuget package. It is successfull and showing EPIForm Tab and folder in Edit Mode at LHS Panel.
Now when I creating any new form and draging any control to the form then, it showing message "No rendere found for 'form container'" at Middle Panel of the my master layout. I have partially using Alloy site code.
