How do I get my formview2 databind with an updated image

I have a file upload that overwrite an the old image with a new one. And everything works, except it will not rebind the formview2 control that has the image in it.  I put this line of code in the button click event for the file upload: ‘Formview2.databind()’ but it doesn’t update the image.  Can someone tell me how to do get the form to bind with the new image?

Thanks!
