After updating to the latest version of Telerik, 2016.1.113, in javascript eventArgs.get_commandArgument() when called from an OnClientClicking function is returning null instead of the command argument set on the button. The same applies to the get_commandName function. When using sender.get_commandArgument() the correct value is returned. In previous versions the function called on eventArgs returned the correct value. Was this an intended change or is this a bug?
