How to Add REGION in Visual Studio in aspx Files

Question

I use asp.net with code behind and c#.

So I have two file for every .aspx page in VS 2010.

In .aspx.cs page I am able to add regions in my code using:

#region Name Region
#endregion

My questions:

• How to do it in file .aspx? #region seems working only in .cs file.
• Do you know any other useful tag to help me to organize better my code both for .aspx and .cs file?
• Do you know the keyboard shortcuts to expand or collapse all my region in my code?

Thanks for your help.

Answer 1

Do you know the keyboard shortcuts to expand or collapse all my region in my code?

Here are some key chords for you.

Ctrl-M Ctrl-O will collapse all the regions in the opened document (or the highlighted section).

Ctrl-M Ctrl-M will collapse or open the collapsible section the cursor is on.

Ctrl-M Ctrl-L will collapse or open everything.

Now here is one i use frequently, especially in javascript files: highlight some code, then press Ctrl-M Ctrl-H to hide it, which will produce a little expander +- next to the collapsed code. Press Ctrl-M Ctrl-O to expand it again.

Also see this blog post by Scott Guthrie which details some posters you can download with lots of the VS shortcut key combinations on them.

Answer 2

The editor of Visual studio for aspx files already provide features like collapsing and expanding for individual elements of HTML.

You can hit '-' at the left most corner in the editor to collapse the corresponding HTML tag (Div or table, etc.) and sub contents.

Answer 3

You can try putting it inside a some other container. For example
<asp:Literal id="JavaScriptRegion" runat="server">
.... I put all my javascripts here.
</asp:Literal>

So I can collapse the Javasript "region". If it's inside your body section and you have asp ctrols inside you might try something like
<div style="">....

It should be mentioned that if you use the hotkeys:

• CTRL + M , CTRL + O
• CTRL + M , CTRL + M
• CTRL + M , CTRL + L
• CTRL + M , CTRL + T

etc., they wont be saved when you save and reopen your project.
