Question

I need to copy a text from a textbox into the clipboard with ASP.NET. I want a code that is comparable with Mozilla Firefox and IE.

Answer 1

Internet Explorer clipboard copy is trivial:

// set the clipboard var x = 'Whatever you want on the clipboard'; window.clipboardData.setData('Text',x);  // get the clipboard data window.clipboardData.getData('Text'); 

Firefox, not trivial at all. Impossible actually with pure JS unless you have signed scripts etc. There is a workaround using a Flash object, however. Read about it here
