ItemControl绑定数据没效果

ItemControl绑定数据没有效果
在XAML界面上我使用一个ItemControl作为数据容器，然后在它的数据模板里使用了3个控件，代码如下：

            <Style x:Key="GuestTilePanelStyle" TargetType="ItemsControl">
                <Setter Property="xc:xTilePanel.ItemHeight" Value="30" />
                <Setter Property="xc:xTilePanel.ItemWidth" Value="120" />
                <Setter Property="ItemsControl.ItemsPanel">
                    <Setter.Value>
                        <ItemsPanelTemplate>
                            <xc:xTilePanel AnimatesNewItem="True" Attraction="2.0" Dampening="0.40" Variation="1.00" />
                        </ItemsPanelTemplate>
                    </Setter.Value>
                </Setter>
                <Setter Property="ItemsControl.ItemTemplate">
                    <Setter.Value>
                        <DataTemplate>
                            <Grid x:Name="gProgressContainer" Height="30">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="30" />
                                    <ColumnDefinition Width="*" />
                                    <ColumnDefinition Width="20" />
                                </Grid.ColumnDefinitions>
                                <xc:xSprocket x:Name="skProgress" Grid.Column="0" Width="30" Height="30" TickColor="#FF02AA1A" /> 
 
                                <xc:xShadePanel x:Name="spInfo" Grid.Column="1" HorizontalContentAlignment="Center" Transition="UpTransition">
                                    <TextBlock Text="{Binding name}" Foreground="Red" VerticalAlignment="Center" HorizontalAlignment="Center" />
                                </xc:xShadePanel>
                                <xc:xIcoButton x:Name="btnCancel" Grid.Column="2" Width="20" xIconSize="16" xIcon="/Takewin.OS.Modularity.FePlat;component/Resources/i0001000000210003.png" />
                            </Grid>
                        </DataTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

 <ItemsControl x:Name="itcSyncGuest" Grid.Column="0" Margin="0,5,0,0" Width="150" Grid.Row="3" ItemsSource="{Binding}" Style="{StaticResource ResourceKey=GuestTilePanelStyle}" />

在后台代码，我定义了一个类，并使用ObservableCollection来作为ItemsControl的数据源

private class GuestData
{
     public int mid;
     public string name;
}
private ObservableCollection<GuestData> _Source;

在load事件里我初始化并绑定数据源
this._Source = new ObservableCollection<GuestData>();
this.itcSyncGuest.ItemsSource = this._Source;

现在我在BackgroundWorker的DoWork事件里获取到一个DataTable，同时去遍历每一行，将每一行的中的一列数据去更新GuestData对象中的name，但是运行之后没有绑定的效果，也就是数据都没绑定上去，具体代码如下

        private void SyncGuestToSource(int meetId)
        {
            GuestData data = new GuestData() { mid = meetId };
            this._Source.Add(data);
            BackgroundWorker bg = new BackgroundWorker();
            bg.WorkerReportsProgress = true;
            bg.WorkerSupportsCancellation = true;
            bg.DoWork += new DoWorkEventHandler(bg_DoWork);
            bg.ProgressChanged += new ProgressChangedEventHandler(bg_ProgressChanged); 
 
            bg.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bg_RunWorkerCompleted);
            bg.RunWorkerAsync(data);
        }

        private void bg_DoWork(object sender, DoWorkEventArgs e)
        {
            //在数据源中的索引位置
            GuestData data = (GuestData)e.Argument;
            int index = this._Source.IndexOf(data);
            e.Result = index;

            string sql = string.Format("select * from TGuest where KMeetId={0}", data.mid);
            DataTable dtData = this._Dao.QueryDataSet(sql).Tables[0];
            if (dtData != null && dtData.Rows.Count > 0)
            {
                foreach (DataRow dr in dtData.Rows)
                {
                    data.name = Convert.ToString(dr["FName"]);
                    ((BackgroundWorker)sender).ReportProgress(index, data);
                }
            }
        }

        private void bg_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            int index = e.ProgressPercentage;
            GuestData data = (GuestData)e.UserState;
            this._Source[index] = data;
        }

请问是怎么回事？

[解决办法]
能不能调试跟踪一下 _Source ，看看有没有数据上的变化。
[解决办法]
查看你的数据上下文是否正确
[解决办法]
把GuestData实现一下INotifyChanged接口，也就是name属性需要调用通知功能。
[解决办法]

public class ViewModelClass : INotifyPropertyChanged
{
   private string _name;
   public string Name
   {
      get{return _name;}
   }

   ..... 
 

   public void ChangeName(string newName)
   {
      _name=newName;
      OnPropertyChanged("Name");
   }
   
   ......

    public event PropertyChangedEventHandler  PropertyChanged;
    private void OnPropertyChaned(string propName)
   {
      if(PropertyChanged!=null)
      {
         PropertyChanged(this, new PropertyChangedEventArgs(propName));
      }
   }
}
