Nesting View Components in AspView

on November 11, 2007 castle , monorail , aspview edit

Following a request from Gauthier Segay, AspView now supports nested view components.

scenarion: you are using CaptureFor to inject markup from a view to a layout, and you want the injected markup to include a view component output.

in the layout:

...&lt;%=CapturedContent %&gt;...

in the view:

...&lt;component:CaptureFor id="CapturedContent"&gt; Some markup &lt;component:SomeFancyStuff&gt;Fancy component content&lt;/component:SomeFancyStuff&gt;&lt;/component:CaptureFor&gt;

While working on that, I found out yet another problem. nested components of same type would brake

so:

&lt;component:Bold&gt;&lt;component:Bold&gt;stuff&lt;/component:Bold&gt;&lt;/component:Bold&gt;

would brake.

As you probably might know, the whole preprocessing of view, from AspView syntax to standard C# is done with Regular Expressions. For quickly doing the above, I helped myself to http://puzzleware.net/blogs/archive/2005/08/13/22.aspx in order to build the balanced tags aware regular expression, and now it works like a charm. Roy Osherove’s Regulator was helpful, too.

So, as of revision 360 in Castle Contrib repository, nesting view components works (for both the trunk and the RC3 compatible branch)

As usual - go to http://www.aspview.com to get the binaries, or to http://svn.castleproject.org:8080/svn/castlecontrib/viewengines/aspview/ for the sources.

Cheers.
