I had made a list view in sharepoint 2010 which takes first name and last name as input fields. We can add multiple names. For that I have created an update panel to asynchronously add names at front end and after all names added user can submit it. It is working fine in SP2010 but when migrated to SP 2013 it is giving issues.When I hit "Add another Name" then in Chrome and Mozilla the whole page goes for a load(a blank page appears on same window where Add another name was hit) and that loading never ends. Can Anyone help with this update panel.
Have you used java script code for that or you are doing it by code behind?
As Update panel is not supported in Office 365 environment. It is working on SP2013 on premises environment. if you had handled that using Update Panel trigger than it is going to be refresh.
you can use java script code to Add/Remove multiple dynamic controls.
