I am relatively new to dnn. I am using the dnn wrapped versions of the telerik controls. For the dnnAsyncUpload, I need to use some functionality described on the Telerik site

http://demos.telerik.com/aspnet-ajax/asyncupload/examples/validation/defaultcs.aspx

 that uses their own library functions, such as

var $ = $telerik.$;

Unfortunately, this causes conflict with the page. How do I access these functions to customize client side validation for the DNN wrapped controls? I have tried wrapping the functions in various ways that have not worked.
