I have a really interesting problem. We have a site created with sharepoint 2013. We use Windows - NTLM authentication.
In a page includes custom discussionListWebPart, we have a filter button which use javascript doPostBack function with webpart ClientID and filter parameters.
exp: __doPostBack("ClientID","params");
When we do filter, just discussion list webpart do post back and no any request for the any part of Page. That means the page does not reload. This is what we expected.
It works fine in the IE 10 and chrome. Whatsmore, we have problem when we open this page in any ipad. The filter button which we use __doPostBack reloads the page. Also have problem in safari on desktop.
--I controlled the IIS (8) windows authentication providers, there is just NTLM (No negatiate).
-- I found another discussion iOS 8 / Safari 8 not working with ASP.NET AJAX-Extensions.
When I open the site in safari everytime it asks for user credentials. If I say remember password doPostBack works fine.
But I can not do this in ipad. So The problem still exists.
I dont see any console error in dvl tool. But It does not do postBack. Just refresh the page.
Please help to solve this problem. Thanks.
