I'm using Visual Studio 2012 and create a ASP.NET MVC 4 Web Project. After that, I install ASP.NET AJAX Toolkit
by using Package Manager Console
by typing :
Install-Package AjaxControlToolkit
After that, I open a sample cshtml file. In my toolkit, I can use HTML Toolkit
, but AJAX Toolkit
, I can see it, but all items in this toolkit is shallow (dark gray), and I cannot drag and drop it to source screen.
Ajax Control Toolkit is meant to be used with WebForms projects, not MVC. I would imagine that is why it's not working. Use jQuery, and jQuery UI, instead.
