Binding to a property of a list element of a model

Question

I am having a model Model1 with a property as List<Model2> model2;.

Model1.cs

//Other Properties
public List<Model2> model2List {get; set;}

And in Model2 I have this property Model3 model3;

Model2.cs

// Other Properties
public Model3 model3 {get; set;}

Model3.cs

// Other Properties
public string Name {get; set;}

Now I have two User Controls View1 and View2 with View2 defined in View1

View1.xaml UserControl

<Grid x:Name="LayoutRoot">
    <!-- Some properties here bind to those of model1 and model2 -->
    <views:View2 Name="view2"></views:View2>
</Grid>

View2.xaml UserControl

<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}">
      <phone:LongListSelector
          ItemsSource="{Binding Path=model3, Mode=OneWay}">
          <phone:LongListSelector.ItemTemplate>
              <DataTemplate>
                  <StackPanel>
                      <Border
                          BorderBrush="{StaticResource PhoneBackgroundBrush}"
                          BorderThickness="3"
                          Margin="0,12">
                          <Grid>
                          <TextBlock Text={Binding Path=Name, Mode=OneWay}>
                          </TextBlock>
                      </Border>
                      <views:View3 Name="view3">
                      </views:View3>
                  </StackPanel>
              </DataTemplate>
          </phone:LongListSelector.ItemTemplate>
      </phone:LongListSelector>    
</Grid>

I am trying to bind TextBlock in View2.xaml to Property name in Model3. From my CS I have set DataContext as

view2.DataContext = model1Object.model2List;

Doesn't seem to be working. Also I need to bind controls in my view3 defined in view2 with properties of model3. I know this looks too confusing but I am stuck. Help!

So, first question => do you have something display in screen when you launch app? your list is loaded with items? model3 need to be a list. — MatDev8

Those aren't properties. Those are fields. You cannot bind to fields.

Change your fields into properties by using automatic property definitions.

public Model3 Model3 {get;set;} // PascalCase for property names, thx

This may not be the only issue, but it's definitely incorrect to try and bind against fields.
