Refresh Panel triggers postback after a period of dormancy

Within my SharePoint solution, I have incorporated an asp.net user control that utilizes Telerik Asp.net Ajax controls to facilitate basic datagrid CRUD operations. This grid is utilized within a web part on a SharePoint 2013 page.

The datagrid is enclosed in a RadAjaxPanel for ajax functionality.

Overall, everything functions properly. However, if I click the "add new record" button and leave the form untouched for some time before filling it out and submitting, a postback occurs which cancels the form submission.

Oddly enough, if I immediately fill out the form after clicking "add new record" and submit it, there are no issues. I suspect there may be a timeout setting causing this problem, but despite spending two days researching, I have been unable to locate it.

I am curious to know if you have encountered a similar problem before. Whether it involves an Asp.net update panel or RadAjaxUpdatePanel, any insights would be greatly appreciated.

Since I am unsure of which portion of the code to provide, please inform me if you require any specific code samples to better understand the issue at hand.

There seems to be something related to the SharePoint script manager and ajax manager causing this issue, though I am uncertain of the exact source.

Answer №1

There seems to be a known bug in SharePoint 2013 that has been causing issues for users. Despite suggestions to install the December 2014 CU to fix it, this solution did not work. One user shared on this link that making periodic requests to the server via JavaScript events helped resolve their issue. In my case, I noticed that my page would refresh if left idle for about 20-30 seconds, so I implemented calling a random SP web service every 15 seconds, which seemed to work as a temporary workaround. For more details on how I tackled this problem, refer to the link provided below.
