sql server - Entity Framework gives me the old data although i changed them -


i have strange problem entity framework:

i have sql server database on windows server , access via app through entity framework.

now changed entry in database, app uses entity framework still gives me old value although not saved in place.

what , how fix this?

edit:
i'm getting data database this: 

(from p in _myef.master_items p.id == userid   select p.location).firstordefault();

edit2:
when start locally via visual studio see new value. if use deployed version, see old value not in db anymore

edit3: here connection string <add name="myentities" connectionstring="metadata=res://*/mydata.csdl|res://*/mydata.ssdl|res://*/mydata.msl;provider=system.data.sqlclient;provider connection string=&quot;data source=foo;initial catalog=mydb;persist security info=true;user id=admin;password=xxxx;multipleactiveresultsets=true;app=entityframework&quot;" providername="system.data.entityclient" />

entity framework caches objects internally in dbcontext instance. meant short-lived, purpose of caching every time entity same id same actual instance of said entity back.

this means when using entity framework, shouldn't store dbcontext in static field. create new 1 every request.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
