binding the custom object list to datagrid in silverlight 4

Source XML

<?xml version="1.0" ?>
<songs>
  <song sname="song1.mp3"/>
  <song sname="song2.mp3"/>
  <song sname="song3.mp3"/>
  <song sname="song4.mp3"/>
</songs>

XAML

<sdk:DataGrid 
            x:Name="DataGrid1" 
            Margin="0,60,0,0" 
            IsReadOnly="T开发者_开发问答rue"
            AutoGenerateColumns="True" 
            VerticalScrollBarVisibility="Visible" 
            BorderBrush="DarkGreen" 
            BorderThickness="5" 
            CanUserSortColumns="True" 
            CanUserResizeColumns="False" 
            CanUserReorderColumns="False">
</sdk:DataGrid>

Binding Code

 void ParseXMLFile(string dataInXmlFile)
        {

            List<Song> songs = new List<Song>();

            XDocument xmlDoc = XDocument.Parse(dataInXmlFile);
            songs = (from r in xmlDoc.Descendants("song")
                     select new Song
                     {
                         name = (string)r.Attribute("sname").Value
                     }).ToList();

            DataGrid1.ItemsSource = songs;
        }

When the above code runs - the datagrid is empty.

While debugging i can see the object songs have 4 items.

the issue is it not binding properly - any suggestion appreciated.

You haven't shown us the source of your Song class.

I suspect you've declared the name property as internal. You need to to be public for it to work in a DataGrid.

Replace your code part

DataGrid1.ItemsSource = songs;

with

DataGrid1.ItemsSource = null;
DataGrid1.ItemsSource = songs;

While it looks stupid, this works for me
