C# Silverlight 4-相关表datagrid显示排序

我正在使用中的示例代码将相关数据显示到数据网格中。在我的数据中，我需要按年份对表进行排序（我的相关表中的一个名为“\u year”的属性）。我不知道如何在xaml或c#中实现这一点。以下是我目前的代码：

xaml：

C#：

private void SelectedRoadsTreeView\u SelectedItemChanged（对象发送方，RoutedPropertyChangedEventArgs e）
{
如果（e.OldValue！=null）
{
图形g=e。作为图形的旧值；
g、 取消选择（）；
g、 SetZIndex（0）；
}
如果（如NewValue！=null）
{
图形g=e，新值为图形；
g、 选择（）；
g、 SetZIndex（1）；
//关系查询
RelationshipParameter relationshipParameters=新的RelationshipParameter（）
{
objectId=new int[]{Convert.ToInt32（g.Attributes[SelectedRoadsTreeView.Tag as string]），
外场=新串[]{“loc_id，count_id，_year，adt”}，
RelationshipId=0，
OutSpatialReference=Map.SpatialReference
};
queryTask.ExecuteRelationshipQueryAsync（关系参数）；
MyChart2.Title=g.Attributes[“TrafficCounts.COUNTUSER.%segment\u master.\u street”]；
}
}
void QueryTask\u ExecuterRelationshipQueryCompleted（对象发送方，RelationshipEventArgs e）
{
关系结果pr=e.结果；
if（pr.RelatedRecordsGroup.Count==0）
{
RelatedRowsDataGrid.ItemsSource=null；
}
其他的
{
foreach（pr.RelatedRecordsGroup中的变量对）
{
RelatedRowsDataGrid.ItemsSource=pair.Value；
//？.SortDescriptions.Add（新系统.ComponentModel.SortDescription（“属性[_年]”，系统.ComponentModel.ListSortDirection.升序））；
（（ColumnSeries）MyChart2.Series[0]）.ItemsSource=pair.Value；//new KeyValuePair[]{new KeyValuePair（20051200）}；
}
}
}

谢谢

此代码应该可以帮助您

 bool SortDateAsc = true;
    private void Date_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        if (SortDateAsc)
        {
            ObservableCollection<InvoicesDTO> a = new ObservableCollection<InvoicesDTO>(((ResolutionVM)this.DataContext).MainInvoiceList.OrderBy(oc => oc.FC_AGE));
            ((ResolutionVM)this.DataContext).MainInvoiceList = a;
            InvoiceGrid.ItemsSource = ((ResolutionVM)this.DataContext).MainInvoiceList.ToList();
            SortDateAsc = false;
            ((ResolutionVM)this.DataContext).RefreshSelctedInvoice();
        }
        else
        {
            ObservableCollection<InvoicesDTO> a = new ObservableCollection<InvoicesDTO>(((ResolutionVM)this.DataContext).MainInvoiceList.OrderByDescending(oc => oc.FC_AGE));
            ((ResolutionVM)this.DataContext).MainInvoiceList = a;
            InvoiceGrid.ItemsSource = ((ResolutionVM)this.DataContext).MainInvoiceList.ToList();
            SortDateAsc = true;
            ((ResolutionVM)this.DataContext).RefreshSelctedInvoice();
        }

    }

bool-SortDateAsc=true；
私有作废日期\u MouseLeftButtonDown（对象发送者，MouseButtonEventArgs e）
{
if（SortDateAsc）
{
ObservableCollection a=新的ObservableCollection（（（ResolutionVM）this.DataContext）.MainInvoiceList.OrderBy（oc=>oc.FC_年龄））；
