xaml - Using the same ListView on two PivotItems without code duplication -

i'm working on shopping windows phone 8.1 application, have "promotions" page. page pivot page 2 pivotitems. first item shows top 100 promotions, , second item shows promotions. data call webservice. data has same structure in both cases, use same listview , datatemplate on both pages. question is: how can avoid code duplication in scenario? how can use same listview , datatemplate on 2 pivotitems without copy-pasting xaml , code?

you need create property in viewmodel takes filter of first this:

    public observablecollection<itemmodel> itemlist { get; set; }     public ienumerable<itemmodel> top100list { { return (from in itemlist select i).take(100); } } 

then bind each listview appropriate property. example assumes top 100 items first 100 items in list. if not, either have modfy linq statement or sort list when adding items.
