Please add support for JQuery 3.x to Telerik ASP.NET for AJAX. I am able to integrate Telerik into a nice Bootstrap dashboard, but the jquery versions are no compatible. Telerik is further behind on the jQuery version.
Right after I posted I upgraded and also incorporated jquery migrate. I also discovered I forgot to remove a script I had registered on page load in my c# code. It's working beautifully. I'm not sure what part of that fixed my original issue, but it's working. I included the JQuery 3.1 file included in the original bootstrap download. After that I also included JQuery Migrate 1.4.1 After that I added EnableEmbeddedJQuery="false" to my RadScriptManager. JQuery Migrate: https://code.jquery.com/jquery-migrate-1.4.1.js I attached parts of my solution in case someone runs into issues down the road. Bootstrap and Telerik combined make a very nice solution. It allows you to focus on development instead of styling. I'm very happy with both solutions.
I have good news that R2 2017 SP1 (version 2017.2.621) introduces jQuery 3 compatibility improvements. My advice is to give it a spin.
