Regions In ASP.NET Views?

I am making an ASP.NET MVC application with the razor engine.

And I was wondering if it's possible to use Regions in a view.

something like:

#region blabla
    <p>@Model.Name</p>
    <p&g开发者_如何转开发t;...</p>
#endregion

This does not work. Is there an alternative?

This works in Visual Studio 2015 and above (thanks to @dotnetN00b for the sample in the comments section):

<!-- #region Test -->

code here

<!-- #endregion -->

---

Select the part which needs to be converted to region, then right click and press CollapseTag

---

In Visual Studio (2015 and above) .html or .cshtml code editor, type region, then press Tab key.This implements #region snippet code like below:

<!-- #region name -->

//Your html or cshtml codes

<!-- #endregion -->.

In Visual Studio, you can manually add outlined region like this :

To create or remove a collapsible region

1. Select the text you want to treat as a collapsible region.

2. To create a collapsible region, on the Edit menu, point to Outlining, and then click Hide Selection.

The editor turns the selection into a region, collapses it, and displays a box with an ellipsis (...) to indicate that the area contains a collapsed area. You can hold the mouse pointer over the box to see its contents.

3. To remove a collapsible region, collapse it, and then click it to select it.

4. On the Edit menu, point to Outlining, and then click Stop Hiding Current.

To collapse and expand a single region

1. To collapse a region, click the minus sign (-) in the margin of the editor.

2. To expand a collapsed region, click the plus sign (+) in the margin.

To collapse and expand all regions

On the Edit menu, point to Outlining, and then click Toggle All Outlining.

From MSDN

But that's not really practical.

For HTML you can manually edit the outline option for each tags in the text editors options :

Minimum value of minimum lines is 1 to be effective.

I don't have "CollapseTag" option in my context menu. What I usually do is :

1. Select text.
2. Goto Edit -> Outlining -> Hide Selection.

or

use Ctrl+M, Ctrl+H

I am using Microsoft Visual Studio Pro 2013.

No, AFAIK it is not possible to use regions in a view. You could use partials to group regions of the view into reusable partial views.

See the newer answer; it works and accomplishes the desired effect.

---

Divs are collapsible so you could always use them with some sort an id to kind of mimic regions.

<div id="BLABLA">...</div>

---

You can use Masterpages with RenderPartial or RenderAction to make your views smaller. Both have their places.

regions sort-of work in views for me, I can define a region but it will not collapse. If you use @Artur's method of using Collapse Tag you're pretty much there! :)

Be aware that using regions can cause issues in views - even though they are syntactically valid, often the designation between code and HTML/SCRIPT becomes 'confused', resulting in unpredictable behavior.

DIVs are certainly the 'better' solution, especially as extra DIVs allow more flexibility when changing CSS styles later.

If you need lots of regions, then consider refactoring your code further.
