Regions In ASP.NET Views?
asp.net Mvcasp.net Mvc-3ViewsRazorRegionasp.net Mvc Problem Overview
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>...</p>
#endregion
This does not work. Is there an alternative?
asp.net Mvc Solutions
Solution 1 - asp.net Mvc
This works in Visual Studio 2015 and above
(thanks to @dotnetN00b
for the sample in the comments section):
<!-- #region Test -->
code here
<!-- #endregion -->
Solution 2 - asp.net Mvc
Select the part which needs to be converted to region, then right click and press CollapseTag
Solution 3 - asp.net Mvc
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.
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 :
- Select text.
- 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.
Solution 7 - asp.net Mvc
Divs are collapsible so you could always use them with some sort an id to kind of mimic regions.
<div id="BLABLA">...</div>
Solution 8 - asp.net Mvc
You can use Masterpages with RenderPartial
or RenderAction
to make your views smaller. Both have their places.
Solution 9 - asp.net Mvc
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! :)
Solution 10 - asp.net Mvc
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.
