c# - ListView DataBindig using MVVM (WPF, ListView, Binding) -

i have model called listviewmodel 1 method:

namespace layoutmvvm.viewmodels {     public class listviewmodel     {         public void getdata()         {         testviewclassdatacontext tv = new testviewclassdatacontext();         list<test_view> tvq = (from tt in tv.test_views                                select tt).tolist();         }     } } 

into usercontrol called listview want result model , bind list:

listview.xaml:

<usercontrol .....>         <grid background="crimson">          <listview width="230" height="250"  name="lvmylist">             <listview.view>                 <gridview>                     <gridviewcolumn header="firstname" width="90" displaymemberbinding="{binding firstname}" />                     <gridviewcolumn header="lastname" width="90" displaymemberbinding="{binding lastname}" />                     <gridviewcolumn header="type" width="50" displaymemberbinding="{binding type}" />                 </gridview>             </listview.view>         </listview>      </grid> </usercontrol> 

listview.cs

namespace layoutmvvm.views {     public partial class listview : usercontrol     {         public listview()         {             initializecomponent();              listviewmodel lvm = new listviewmodel();             lvmylist.itemssource = lvm.getdata(); //error          }     } } 

i'm starting wpf , don't know how correclty bind data.

probably should change method follows, method return actual results,

public list<test_view> getdata()     {         testviewclassdatacontext tv = new testviewclassdatacontext();         list<test_view> tvq = (from tt in tv.test_views                                select tt).tolist();         return tvq;     }
