asp.net mvc routing - How to Highlight Active Tab Using Navigation Routes in Twitter Bootstrap MVC4 -

-

my question how highlight active tab using route-based menu system twitter bootstrap mvc4. if parent tab contains child routes, when child route selected, corresponding parent tab should highlighted. please consider example code below , thank help.

below example routeconfig:

    routes.mapnavigationroute<dashcontroller>("parent 1", c => c.index(), "", true);      routes.mapnavigationroute<maincontroller>("parent 2", c => c.index())                     .addchildroute<maincontroller>("child 1", c => c.do_something(), "", true)                     .addchildroute<maincontroller>("child 2", c => c.do_something_else(), "", true) ;

below example _layout shared view:

<div class="nav-collapse collapse">                         <ul class="nav">                              @html.navigation()                         </ul> </div>

in twitterbootstrapmvc there way set links active inside nav using extension methods: .setlinksactivebycontroller() or .setlinksactivebycontrollerandaction()

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...
