My DataTemplate holds two labels in a StackLayout and gets populated from an ItemSource in the ViewModel. I understand how to build most of the content, but how to get the binding to work from code behind isn't something I understand completely. Can you help walk me through using SFListView for something like this?
<sfPopup:PopupView.ContentTemplate>
<DataTemplate>
<CollectionView
x:Name="CodesCollection"
ItemsSource="{Binding CodesReturn}"
SelectionMode="Multiple"
SelectedItems="{Binding CodesSelected, Mode=TwoWay}">
<CollectionView.ItemTemplate>
<DataTemplate>
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand" >
<StackLayout Orientation="Horizontal" Margin="10,5,10,1">
<Label
Margin="10,0,0,0"
Text="{Binding Code}"
FontSize="Default"
FontAttributes="Bold"
HorizontalOptions="Start"/>
<Label
Margin="0,0,10,0"
Text="{Binding Name}"
FontSize="Default"
FontAttributes="Bold"
HorizontalOptions="EndAndExpand"
HorizontalTextAlignment="End"/>
</StackLayout>
<BoxView
VerticalOptions="End"
HorizontalOptions="FillAndExpand"
Margin="15,2,15,2"
HeightRequest="2"
BackgroundColor="{StaticResource DarkGrey}"/>
</StackLayout>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
</DataTemplate>
</sfPopup:PopupView.ContentTemplate>

private CollectionView _collectionView;
public MainPage()
{
........
_collectionView = new CollectionView();
_collectionView.ItemsSource = viewModel.BookInfo;
_collectionView.SelectionMode = SelectionMode.Multiple;
_collectionView.ItemTemplate = new DataTemplate(() => {
StackLayout _ParentstackLayout = new StackLayout();
///----------------------------------------------
StackLayout _stackLayout = new StackLayout();
Label _labelOne = new Label();
......
_labelOne.SetBinding(Label.TextProperty, "BookName", BindingMode.TwoWay);
Label _labelTwo = new Label();
.......
_labelTwo.SetBinding(Label.TextProperty, "BookDescription", BindingMode.TwoWay);
_stackLayout.Children.Add(_labelOne);
_stackLayout.Children.Add(_labelTwo);
//--------------------------------------------------
BoxView _boxView = new BoxView();
......
_ParentstackLayout.Children.Add(_stackLayout);
_ParentstackLayout.Children.Add(_boxView);
return _ParentstackLayout;
});
_popupContent.ContentTemplate = new DataTemplate(() => {
return _collectionView;
});
