datagrid擴展器+ RowDetailsVisibilityChanged

我有一個嵌套的網格，當我點擊一個數據網格（使用RowDetailsVisibilityChanged）時，工作正常。之後，我插入了一個擴展器，現在我有問題把它放在一起。問題是擴展器擴展時調用的方法有（對象發件人，RoutedEventArgs e）和rowdetails有（對象發件人，DataGridRowDetailsEventArgs e）。我的擴展器適用於擴展，但不填充嵌套網格中的數據。我可以以某種方式從Expanded方法調用RowDetailsVisibilityChanged嗎？的主要問題是，我必須定義datagrid擴展器+ RowDetailsVisibilityChanged

DataGrid innerDataGrid = e.DetailsElement as DataGrid;

，我不能這樣做，在展開的方法，因爲我沒有DataGridRowDetailsEventArgs

擴大，RowDetailsVisibilityChanged方法：

private void tabela_RowDetailsVisibilityChanged(object sender, DataGridRowDetailsEventArgs e) 
{ 
    DataGrid innerDataGrid = e.DetailsElement as DataGrid; 
    string ConString = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString; 
    string query = "SELECT StanjeTR.Firma, StanjeTR.NazFirme, StanjeTR.Konto, StanjeTR.NazivKonta, Sum(StanjeTR.Duguje) AS SDuguje, Sum(StanjeTR.Potrazuje) AS SPotrazuje, Sum(StanjeTR.Saldo) AS Stanje, StanjeTR.Valuta, Sum(StanjeTR.DevDuguje) AS DDuguje, Sum(StanjeTR.DevPotrazuje) AS DPotrazuje, Sum(StanjeTR.DevSaldo) AS StanjeDeviza FROM StanjeTR WHERE StanjeTr.Firma = @Firma GROUP BY StanjeTR.Firma, StanjeTR.NazFirme, StanjeTR.Konto, StanjeTR.NazivKonta, StanjeTR.Valuta ORDER BY StanjeTR.Firma, StanjeTR.Konto"; 

    using (SqlConnection con = new SqlConnection(ConString)) 
    { 
     //CmdString = "SELECT emp_id, fname, lname, hire_date FROM Employee"; 
     SqlCommand cmd = new SqlCommand(query, con); 
     SqlDataAdapter sda = new SqlDataAdapter(cmd); 
     cmd.Parameters.Add("@Firma", SqlDbType.Int).Value = Convert.ToInt32(izborID); 
     DataTable dt = new DataTable("StanjeTR"); 
     sda.Fill(dt); 
     innerDataGrid.ItemsSource = dt.DefaultView;  
    } 
} 

private void Expander_Expanded(object sender, RoutedEventArgs e) 
{ 
    for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual) 
    { 
     if (vis is DataGridRow) 
     { 
      var row = (DataGridRow)vis; 
      row.DetailsVisibility = row.DetailsVisibility == Visibility.Visible ? Visibility.Collapsed : Visibility.Visible; 
      break; 
     } 
    } 
} 

private void Expander_Collapsed(object sender, RoutedEventArgs e) 
{ 
    for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual) 
    { 
     if (vis is DataGridRow) 
     { 
      var row = (DataGridRow)vis; 
      row.DetailsVisibility = row.DetailsVisibility == Visibility.Visible ? Visibility.Collapsed : Visibility.Visible; 
      break; 
     } 
    } 
}

我XAML：

<DataGrid Name="tabela" ItemsSource="{Binding}" RowDetailsVisibilityChanged="tabela_RowDetailsVisibilityChanged" AutoGenerateColumns="False" SelectionChanged="tabela_SelectionChanged"> 
    <DataGrid.CellStyle> 
     <Style TargetType="DataGridCell"> 
      <Setter Property="BorderThickness" Value="0"/> 
     </Style> 
    </DataGrid.CellStyle> 

    <DataGrid.RowHeaderTemplate> 
     <DataTemplate> 
      <Expander Expanded="Expander_Expanded" Collapsed="Expander_Collapsed" /> 
     </DataTemplate> 
    </DataGrid.RowHeaderTemplate> 

    <DataGrid.RowDetailsTemplate> 
     <DataTemplate> 
      <DataGrid Name="innerDataGrid" AutoGenerateColumns="False"> 
       <DataGrid.Columns> 
        <DataGridTextColumn Header="Konto" Binding="{Binding Konto}" Width="200" /> 
        <DataGridTextColumn Header="Naziv Konta" Binding="{Binding NazivKonta}" Width="200" /> 
        <DataGridTextColumn Header="SDuguje" Binding="{Binding SDuguje}" Width="200" /> 
        <DataGridTextColumn Header="SPotrazuje" Binding="{Binding SPotrazuje}" Width="200" /> 
       </DataGrid.Columns> 
      </DataGrid> 
     </DataTemplate> 
    </DataGrid.RowDetailsTemplate> 

    <DataGrid.Columns> 
     <DataGridTextColumn Binding="{Binding Firma}" Width="50" Header="Firma"/> 
     <DataGridTextColumn Binding="{Binding NazFirme}" Width="200" Header="Naziv Firme"/> 
     <DataGridTextColumn Binding="{Binding SDuguje}" Width="200" Header="Duguje"/> 
     <DataGridTextColumn Binding="{Binding SPotrazuje}" Width="200" Header="Potrazuje"/> 
     <DataGridTextColumn Binding="{Binding Valuta}" Width="100" Header="Valuta"/> 
     <DataGridTextColumn Binding="{Binding DDuguje}" Width="200" Header="Dev Duguje"/> 
     <DataGridTextColumn Binding="{Binding DPotrazuje}" Width="200" Header="Dev Potrazuje"/> 
     <DataGridTextColumn Binding="{Binding StanjeDeviza}" Width="*" Header="Stanje deviza"/> 
    </DataGrid.Columns> 

</DataGrid>code here

我已經找到了lution。我將我的擴展器添加爲DataGridTemplateColumn，並在擴展器的展開和摺疊事件中添加了Visibility attirbutes。
