I am trying to get the CustomValidator to work with the RadAsyncUpload, but not having any luck.
I have tried the example from here
http://www.telerik.com/community/forums/aspnet-ajax/async-upload/required-validator-and-radasyncupload.aspx but the javascript never fires. What links the 2 controls togther? Normally I would set the ControlToValidate property of the CustomValidator, but that also does not work.
I have simplified the example (Should always fail validataion), but still no luck
