Hi Guys
In VS 2015 I am getting a wavy blue line under a file which pops up a box saying " 'oncopy' is not a valid attribute of element radtextbox' ", plus the same for uncut and onpaste, although the functions themselves do what they are supposed to in the form.
How can I get rid of this warning?
I copied the website code from one machine to another so maybe there is a clue there.
I am using 2016.2 controls
Thanks for your help!
Clive
