c# - Androids' BaseAdapter equivalent in Windows Store apps -

i have large array of integer items want display in listview formatting. on android extend baseadapter (this example of dynamic view/control creation):

public view getview(int position, view convertview, viewgroup parent) {     if(convertview!=null){         //inflate convertview if doesn't exist      }     myview v = (myview)convertview;     v.setid(position);     v.setnumber(myintegerarray[position]);     return v; } 

i know how in c# windows store app. not find meaningful information on topic.

i not want create list (or other itemssource object) everytime, beacuse take memory , slow (i have refresh array values).

xaml-based ui technologies have capability called ui virtualization reduces memory consumption , processing time when dealing large collections of data presented in items-based uis (itemscontrols).

in order allow this, while keeping capability update ui whenever items added/removed/changed in underlying data collection, need databind ui observablecollection<t>:

<listbox itemssource="{binding}"/> 

code behind:

var numbers = enumerable.range(0,100); datacontext = new observablecollection<int>(numbers); 

keep in mind declarative, databinding-based approach in xaml based ui technologies different procedural approach in other frameworks. in xaml, never need create ui elements in procedural code, define them in xaml , databind ui relevant collection of data items, , ui framework takes care of rest.
