asp.net - ASP DevExpress libraries undefined after server migration -

-

i'm having trouble migrating devexpress elements of asp web application 1 server another. copied files , database on new server location , made adjustments web.config file connected new database. got of site working , pulling data correctly, devexpress pieces coming undefined.

as far can tell, references in web.config file , on respective pages correct , dll files listed in bin directory i'm rather stumped why aren't working.

web.config sample

<compilation debug="true" strict="false" explicit="true">    <assemblies>     ...     <add assembly="devexpress.web.aspxgridview.v10.1, version=10.1.6.0, culture=neutral, publickeytoken=b88d1754d700e49a" />     <add assembly="devexpress.web.v10.1, version=10.1.6.0, culture=neutral, publickeytoken=b88d1754d700e49a" />     ... , on

dashboard.aspx sample

...at top of page... <%@ register assembly="devexpress.web.aspxgridview.v10.1, version=10.1.6.0, culture=neutral, publickeytoken=b88d1754d700e49a" namespace="devexpress.web.aspxgridview" tagprefix="dx" %>

this inherited project, haven't tried rebuilding application in case machine imports settings project (example: made in vs 2008, , i'm running vs community 2015).

are there quirks making transfer don't know or has else experienced issue? appreciated.

thanks

the first thing comes mind version 10.1 of devexpress old version, released in aug '10. not support .net 4, you'll need make sure application pool iis running web app .net clr version 2.0.

note if running in windows server 2012, it's tricky install .net 3.5. google how if need to.

the next check of course if of dll's referenced in bin folder.

could write error message getting? if not have information, perhaps event viewer of server (under windows logs/applications) has more detailed description.

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...
