I have two questions regarding the client side API of the RadColorPicker.
1. How am I supposed to know what is avaliable in the eventArgs of the OnClientColorChanged client side event handler? The documentation sample http://www.telerik.com/help/aspnet-ajax/color_clientonclientcolorchange.html
references the use of eventArgs.get_oldColor() but the documentation of the client object http://www.telerik.com/help/aspnet-ajax/color_clientobject.html
does not talk about the "get_oldColor()".
2. How can I add items to the client side event args? What I would like to add is the client id of a textbox that should be updated when the selected color is changed. More specifically I would like to set the client id of the textbox to update from the server (c# code) so I can reference the passed in eventArgs to get the id of the textbox to update.
