i have background worker performs loading of data database temporary structure. data d = new data(); d.listgroup = context.groups.getnewbindinglist(); d.tbuser = context.users.orderby(x => x.name); d.listpricelevel = context.pricelevels.getnewbindinglist(); e.result = d; the problem 3rd line (d.tbuser = ... ) being lazy-loaded. sure, can do: context.users.orderby( x => x.name ).tolist(); but again, not bindable list, changes made won't propagate db. so think need like: d.tbuser = context.users.orderby( x => x.name ).getnewbindinglist(); but doesn't work. goal is: retrieve list of users, ordered name bind-able list. ideas? thanks time! adding orderby (like of other query functions) turns query iqueryable<tentity> . fortunately, linq-to-sql's internal query type ( dataquery<tentity> ) provides bindinglist<tentity> via implementation of ilistsource . to bindinglist given query, can this: var bindinglist = (

i having hard time understanding difference between max , min cardinalities when trying design database. remember cardinality relationship thing. max cardinality(cardinality) 1 or many. class has relationship package b cardinality of one, means @ there can 1 occurance of class in package. opposite package has max cardnality of n, mean there can n number of classes min cardinality(optionality) means "required." 0 or 1. 0 mean 0 or more, 1 ore more there tons of articles out there explain this, including explain how property "diagram" . thing can search cardinality/optionality (omg terms) explains same thing, optionality "min" cardinality "max", from http://www.databasecentral.info/faq.htm q: can see how maximum cardinality used when creating relationships between data tables. however, don't see how minimal cardinality applies database design. missing? a: correct in noticing maximum cardinality more impo

i have jquery class within normal class in javascript. possible access variables in scope of parent class callback function in jquery class? a simple example of mean shown below var simpleclass = function () { this.status = "pending"; this.target = jqueryobject; this.updatestatus = function() { this.target.fadeout("fast",function () { this.status = "complete"; //this needs update parent class }); }; }; now in above example, callback function tries access scope of jquery object. there way access status variable in parent class? you set "this" variable in parent function , use in inner function. var simpleclass = function () { this.status = "pending"; this.target = jqueryobject; var parent = this; this.updatestatus = function() { this.jqueryobject.fadeout("fast",function () {

can gwt's valuelistbox support multiple selections? also, there way display more single value @ time (like listbox.setvisibleitemcount()) ? it seems you'd need @ underlying listbox (or somehow provide custom one) in order make happen. of course getlistbox() private, that's out. no. valuelistbox intended operate on single value. that's why can used editor (from editor framework) wrapped type. multiple selection can use listbox, afaik there's no straightforward way use editor (you have write own custom editor based on listbox).
