Binding in Nested List Boxes to multiple classes - windows-phone-7

Question

I'm making a nested listed box , basically because I need to bind multiple classes in a single list box , which I'm not able to do and hence the nested listed box.
Here's what I do in the XAML page :
<ListBox Name="abcd" Margin="10,0,30,0" ItemsSource="{Binding Title}" SelectionChanged="ListBox_SelectionChanged" Height="486" Width="404" FontSize="20">
<ListBox.ItemTemplate>
<DataTemplate >
<StackPanel Margin="0,0,10,0" Width="380" Height="140">
<Grid >
<TextBlock Text="{Binding cdata}" TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeLarge}" />
<ListBox Name="ab" ItemsSource="{Binding Description}" FontSize="14">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Width="380" Height="100">
<Grid>
<TextBlock Text="{Binding cdata}" TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeLarge}" />
</Grid>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
where ListBox "abcd" has to be bound with class title and "ab" to the class Description.Both the classes have just one string field , "cdata".
In the xaml.cs I do :
abcd.ItemsSource=from article in root.openfooty.news.article
select new Classes.Title
{
cdata = article.title.cdata
};
ab.ItemSource = from article in root.openfooty.news.article
select new Classes.Description
{
cdata = article.description.cdata
};
binding with "abcd" works fine but with "ab" it says "the nam ab doesnt exist in the current context"
Any help would be much appreciated. Thanks :D

Answer 1

Why don't you write a single class like this
public class TitleDescription
{
public string title { get; set; }
public string description { get; set; }
}
and try the databinding ?
abcd.ItemsSource=from article in root.openfooty.news.article
select new Classes.TitleDescription
{
title = article.title.cdata,
description = article.description.cdata
};
And have only one list box like this
<ListBox Name="abcd" Margin="10,0,30,0" SelectionChanged="ListBox_SelectionChanged" Height="486" Width="404" FontSize="20">
<ListBox.ItemTemplate>
<DataTemplate >
<StackPanel Margin="0,0,10,0" Width="380" Height="140">
<Grid >
<TextBlock Text="{Binding description}" TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeLarge}" />
<TextBlock Text="{Binding title}" TextWrapping="Wrap" FontSize="{StaticResource PhoneFontSizeLarge}" />
</Grid>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
