In SharePoint 2013 after migration from SharePoint 2010, the launch form dialogue box is selected yes in advanced list settings.
So the Edit form for each item opens as a form and there is an attachment icon on this edit form. So when the attachment is clicked an attachment form is opened and displayed as shown in image below.
The classes, id's and pagetype are same for edit form and attachment form. Can anyone suggest me how to make the changes as it is repeated to all the lists in the site.
We do not use SharePoint designer. The site is a customized one developed by using Visual Studio.
