It works fine when page is 61 or smaller, but the moment you increase it to 62, and higher you get a system.webforms.pagerequestmanagerservererrorexception 500. There is nothing wrong with the data because for testing purpose the query is a union of rows that work. Image of the error attached.

Hello Martin,

I tried to replicate the described problem locally in our tooltipified demo, however it is working properly. Can you let me know what is the difference in your case?

Kind regards,

Got the problem fix. Microsoft added a limit on the size of the collection, set it to 1000. So the 61 rows, went over. By debugging inside the AJAX request I got a meaningful error, and was able to locate the solution, which is in web.config
    <appSettings>
        <add key="aspnet:MaxHttpCollectionKeys" value="2000" />
    </appSettings>
