hi ! I´m new in this forum but I use Telerik by many years ago...
I changed by other computer my desktop, and install VS with Telerik, but this dont work in the designer of VB.. so sorry by my english.
this is the problem:
I add by reference
I add the instance in the top of the page
I add in the web.config
but I can see the result in the browser, but dont work in the designer.
I upgraded my computer to windows 10, and I have VS 2012, and Ajax Control Tool Kit
