I have been scratching my head on this for a few hours now and i have no clue what to do. For some reason, in my project, i am having a problem accessing client-side api's for radcontrols. Below is a screenshot of my javascript error and code. All i am doing is calling a webservice, obtaining json, and then trying to populate the grid control with the json array.
