Is it a way that we could capture the event whenever we use the mouse to paste some value to a textbox?

For instance, when I use the mouse to paste a value into a text box, I would to immediately capture this event and called a function to manipulate the given value.

Thanks for any advise.

There is an 'onpaste' event, I believe. I've never used it, and it probably picks up CTRL-v too, but it might be useful for you
