ReportViewer background WebForm problem

Hello all,

I have a webform with a ReportViewer control in ProcessingMode= Local. I put a BackgroundImage on my rdlc with the Source=Embedded and some textboxes. The ReportViewer loads at runtime this rdlc correctly ...the background appears but the problem is that when I try to scroll down or to zoom, only the data from the textboxes are 'scrolled' or 'zoomed'...am I missing something What can I do to scroll and zoom in/out the background, too

I've tried to put an Image on my rdlc with an embedded source with the option Send To Back and the textboxes over the Image. I've seen that at runtime the image is scrolled and zoomed but the data from the textboxes does not appear on the image...but down the page, after the image. :(

I don't have any ideas...Can you help me

Thanks in advance,

Nelly
