I have development experience in SharePoint 2010 but 2013 is new for me as branding is different in 2013 version. To start my question first i need to provide basic info so you guys can answer me in a better way.
SharePoint Environment: SharePoint 2013 (Enterprise version)
Tools: Visual Studio 2013 (Ultimate version)
Scope of my work: I need to develop a Visual WebPart to retrieve some fields from SharePoint list and display in repeater control with pagination with AJAX functionality so page wont post.
Now my question is how to incorporate AJAX in Visual Webpart development to achieve my goal using 4.5 framework.
For this I have tried http://sharepointajax.codeplex.com and following the tutorial http://andreaswijayablog.blogspot.com/2013/12/ajax-control-toolkit-with-sharepoint.html?showComment=1407581200289#c583061232821173847
Followed the above tutorial but can't get success in following the instruction which says "5. Replace the default ScriptManager in your masterpage with the ToolkitScriptManager"
getting the error "The ID 'ScriptManager' is already used by another control." cause .master automatically generates this and I am unable to edit .master directly to comment out or remove ...
OR is there any alternate using JQuery or something to achieve this if I dont want to use AjaxToolKit? any suggestions.
