c# - Binding a DataGrid -

i've created code-first c# project entity framework , wpf. have created entity named personel entity. i'm dragging , dropping entity mainwindow doesn't show data. think have in mainwindow.xaml.cs file don't know do. here datagrid code in xaml:

<datagrid x:name="personelentitydatagrid" autogeneratecolumns="false" enablerowvirtualization="true" itemssource="{binding}" margin="19,259,18,10" rowdetailsvisibilitymode="visiblewhenselected">     <datagrid.columns>         <datagridtextcolumn x:name="addresscolumn" binding="{binding address}" header="address" width="sizetoheader"/>         <datagridtextcolumn x:name="agecolumn" binding="{binding age}" header="age" width="sizetoheader"/>         <datagridtextcolumn x:name="idcolumn" binding="{binding id}" header="id" width="sizetoheader"/>         <datagridtextcolumn x:name="namecolumn" binding="{binding name}" header="name" width="sizetoheader"/>         <datagridtextcolumn x:name="phonenumbercolumn" binding="{binding phonenumber}" header="phone number" width="sizetoheader"/>     </datagrid.columns> </datagrid> 

here code in mainwindow.xaml.cs file :

public partial class mainwindow : window {     private personelcontext _context = new personelcontext();      public mainwindow()     {         initializecomponent();     }      private void window_loaded(object sender, routedeventargs e)     {         system.windows.data.collectionviewsource personelentityviewsource = ((system.windows.data.collectionviewsource)(this.findresource("personelentityviewsource")));         } } 

here code in personelcontext.cs file :

namespace personel {     public class personelcontext : dbcontext     {         public dbset<personelentity> personels { get; set; }     } } 

there nothing else datagrid in code. know need add don't know add. can tell me do?

make 1 change in xaml below

itemsource= {binding}    itemsource= {binding path=.} 

and in code behind

personelentitydatagrid.itemsource =_context.personels.tolist(); 

(if above not works try or part).

or

personelentitydatagrid.datacontext =_context.personels.tolist();
