asp.net mvc 3 - CQRS Commands as Models for POST actions -

-

i'm getting started cqrs, , thought make sense use command object model on forms. can take advantage of of client-side validation commands using dataannotations, client-side validation, makes pretty clean...

my question... raise problems? if command not have default constructor, make process impossible? need create own commandmodelbinder can constructor inject aggregate id?

your thoughts, can't find technique anywhere , im assuming because doesn't work.

i'd recommend take @ greg young's article on task-based ui's on how dtos , messages interact system (both client-side , server-side).

i agree sebastian commands match user interface like. result, you'll need have separate dto/model classes , commands. that's not bad thing model result of query-side of system , shouldn't exact duplicate of messages you're sending system.

also, keeping commands separate model, concern command constructors goes away. controller collects information client, constructs command , submits it.

if you're getting started cqrs, greg's site (cqrsinfo.com) pretty good, 6 1/2 hours video. yes, it's 6 1/2 hours, great introduction , overview of cqrs about. helped me out tremendously.

hope helps!

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
