I just HAD to pass this along. Just today I was bitching about not being able to hide long ASP code in a legacy project I'm maintaining.
One of the things I love about the C# editor in VS.NET is how it lets you collapse regions into a little plus sign. Then when I want it back I can just click to plus to see what's there.
I'm currently working on a Windows SharePoint Services (WSS) Site Definition and I'm using VS.NET to edit the template ASPX files. What I really wanted was a way to collapse table and div tags down into plus signs so I could get the out of my way.
Well, it turns out you can do it!
Select the text you want to collapse, and choose Outlining | Hide Selection from the Edit menu (or just use CTRL-M, CTRL-H).
POW! The file now has a collapsed region. You can open and close that region by clicking the plug sign or using CTRL-M, CTRL-M.
BTW... so far this works in any text file you open in VS.NET. We'll see if that keeps up.
