c# - How to save radiobutton data in MVC controller edit method? -

-

in edit page, have 2 radio buttons gender, once user selected gender male or female, value should saved in database.

i tried solutions proposed, none works.

here view page:

        <div class="form-group">         @html.labelfor(model => model.ismale, htmlattributes: new { @class = "control-label col-md-2" })         <div class="radioleft col-sm-3">             @html.radiobuttonfor(model => model.ismale, "male", new { @checked = true })male             @html.radiobuttonfor(model => model.ismale, "female", new { @checked = false })female             @html.validationmessagefor(model => model.ismale, "", new { @class = "text-danger" })         </div>     </div>

here controller edit method:

    [httppost]     [validateantiforgerytoken]     public actionresult edit( webuser webuser)     {         if (modelstate.isvalid)         {              db.entry(webuser).state = entitystate.modified;                        db.savechanges();             return redirecttoaction("index");         }         return view(webuser);     }

your type nullable<bool>, you're sending either string "male" or "female". how modelbinder supposed know 1 means true , means false? if you've got bool type need pass boolean, example:

@html.radiobuttonfor(model => model.ismale, true) male @html.radiobuttonfor(model => model.ismale, false) female

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
