wpf listbox中的checkbox怎么绑定后台查询出来的数据

我后台查询出来了数据，怎么在前台绑定上，绑定到checkbox上，然后根据后台查询的数据个数自动添加checkbox
前台页面显示：

 <Setter Property="Background" Value="Transparent"></Setter> <Setter Property="ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <toolkit:WrapPanel Orientation="Horizontal" /> </ItemsPanelTemplate> </Setter.Value> </Setter> <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled"></Setter> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <ListBox x:Name="listBox" Grid.Row="1" ItemsSource="{Binding Path=Dae, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal">  <TextBox Text="{Binding Path=USRCD, Mode=TwoWay}" Background="Transparent" Width="Auto"></TextBox> <CheckBox FontSize="14" Content="{Binding Path=USRCD, Mode=TwoWay}" Command="{Binding Path=USRCD, Mode=TwoWay}" IsChecked="{Binding Path=USRCD, Mode=TwoWay}" x:Name="check"></CheckBox> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </ControlTemplate> </Setter.Value> </Setter>

            后台页面查询数据：
            public ICommand QueryPersonnel { get { return new DelegateCommand(OnQueryPersonnel); } }
    void OnQueryPersonnel()
    {
            IsBusy = true;
        BusyText = "正在加载 ...";
        _dsm.Load(_dsm.GetTUSRQuery()).Completed += (oo, ee) =>
        {
            LoadOperation<T_USR> loap = (LoadOperation<T_USR>)oo;
                            IsBusy = false;
            if (loap.HasError)
            {
                MessageBox.Show("加载失败！");
                return;
            }
            _Dae = new PagedCollectionView(loap.Entities);
            RaisePropertyChanged(() => Dae);
            PersonDeptManual addInoWin = new PersonDeptManual();
                            addInoWin.Show();
        };
    }；


            显示在一个弹出的页面

前台显示：

 <Setter Property="Background" Value="Transparent"></Setter> <Setter Property="ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <toolkit:WrapPanel Orientation="Horizontal" /> </ItemsPanelTemplate> </Setter.Value> </Setter> <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled"></Setter> <Setter Property="Template"> <Setter.Value> <ControlTemplate>  <ListBox x:Name="listBox" Grid.Row="1" ItemsSource="{Binding Path=Dae, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal">  <TextBox Text="{Binding Path=USRCD, Mode=TwoWay}" Background="Transparent" Width="Auto"></TextBox> <CheckBox FontSize="14" Content="{Binding Path=USRCD, Mode=TwoWay}" Command="{Binding Path=USRCD, Mode=TwoWay}" IsChecked="{Binding Path=USRCD, Mode=TwoWay}" x:Name="check"></CheckBox> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </ControlTemplate> </Setter.Value> </Setter> 

后台绑定：
public ICommand QueryPersonnel { get { return new DelegateCommand(OnQueryPersonnel); } }
void OnQueryPersonnel()
{
IsBusy = true;
BusyText = "正在加载 ...";
_dsm.Load(_dsm.GetTUSRQuery()).Completed += (oo, ee) =>
{
LoadOperation loap = (LoadOperation)oo;
IsBusy = false;
if (loap.HasError)
{
MessageBox.Show("加载失败！");
return;
}
_Dae = new PagedCollectionView(loap.Entities);
RaisePropertyChanged(() => Dae);
}；
}；
