Hi, we're got a RadGrid on a page with a RadAjaxManager and RadAjaxLoadingPanel. On the first operation, using any of the paging, filtering, sorting etc. the grid doesn't appear to be using ajax on postback. Every other operation after that is fine and works as expected. There are no errors on the client or server side. It's a pretty simple page using version 2018.1.117.40. Thanks!
