Can't See Solid Block in Camera -- Source SDK Problem

I never had this problem before, but now whenever I try to make a map I see colored lines instead of a solid block with the texture I chose.
This is what it looks like:

Any idea on how to fix this?

Yeah, just a simple problem, Ok go to your View menu in hammer, click ‘3D Textured Polygons’ and thats you fixed.
