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

Hello Clive,

The oncopy, onpaste, oncut are attributes that are directly applied to the input element which is part of the rendered HTML markup of the RadTextBox control. These attributes are not server properties and for this reason Visual Studio does not recognize them.
