Page width in SSRS

I want ot draw a line the full width of the page in SSRS.

If I could get th开发者_如何学Goe page width in (say) px, I could assign it as an expression to the line width. Is this possible? How? Or is there an alternative?

you can't do this, because a line get the start and end point positions. may be you can set this values to a big number and this solution solve your problem.
