i have binded customer name textbox customer model , set mode 2 way want update edited name database. how can achieve ?

your question vague doesn't whether wanted on propertychanged or when have button either click event handling or icommand binding on it.

the decision when update totally down business model applying. speaking, it's never idea update directly propertychanged event because might temporary edit , may wish update against.

for example, if have updatesourcetrigger=propertychanged, character type, property updated new value , if implmented inotifypropertychanged events, instantly fire update database. because database connection transient, on network, may or may not available, , may or may not timeout during partial update. thus, end locking code or if multi-threading, causing race conditions.

therefore, it's better implement changes via save button or when screen closed/navigated away (such ios/android do).

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...

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.
