Tjaart,

You can easily google to get some JavaScript samples of how to achieve this. Not though that it's very bad usability and your users will hate you.

 $('yourtextboxRuntimeid').bind("cut copy paste",function(e) {
     e.preventDefault();
 });

Hi Tjaart, 

You will find an OML in attach. You will see how it's done. (avoiding the right click paste funtion aswel)

Quick recap :

- Create an expression with escape content to 'no'. (drag it wherever you want)

- In the expression, you will have to write <script type="javascript"....

- In the script, call the document.ready function. 

- Reference your textbox runtime id. (this will be translated automaticly to the html id of the element)

- Disable the paste function

Greetings,

Niels

Thanks
