The "visible area" of a control?

I have a Canvas within a ScrollViewer. The Canvas have a size of 600x600 and the ScrollViewer 400x400. If i scroll to the right side, i can't see 200pxl left side of the Canvas. Therefore my area of Canvas begins at x=200 but actually the visible area at x=0. Is there any way to get so "v开发者_开发问答isile area" of a control by a property or something like that ?
