Topic: I can not contract (collapse) the program text. What can be not so?

Visual Studio 2010 ULTIMATE
When I work in ASP.NET Web Application, VS gives possibility to displace
Units in the program text - "pluses" to the left of the text.
Now I do the project in ASP.NET Web Site (Razor). It was required to add
In project Generic Handler (*.ashx). The text was generated..., but without possibility
To displace separate units.
Question: where it is necessary to deliver "birdie" that there was a possibility to displace
PS. A similar problem with texts on JavaScript-e. But I solve it, using
Notepad ++. It gives the chance to displace units, though too not without focuses.
