傳遞列表框項目到DoubleClick事件

我有這些方法。我可以雙擊收藏列表視圖中的一個項目，並且Double_Click方法會觸發並收到消息框。我無法弄清楚的是如何傳遞項目本身，以便我可以訪問'WWPN'列中的字符串值。我想將它作爲參數傳遞給另一個搜索的方法。這與將發送者重新放回列表項目或端口結果一樣簡單？傳遞列表框項目到DoubleClick事件

private void BrowseFlogiDatabase_Click(object sender, RoutedEventArgs e) 
    { 
     CollectionWindow cw = new CollectionWindow(this.VirtualFabricList); 

     GridView grid = new GridView(); 
     GridViewColumn FCPortColumn = new GridViewColumn(); 
     FCPortColumn.Header = "FC Port"; 
     FCPortColumn.Width = Double.NaN; 
     FCPortColumn.DisplayMemberBinding = new Binding("FCPort"); 

     GridViewColumn WWPNColumn = new GridViewColumn(); 
     WWPNColumn.Header = "WWPN"; 
     WWPNColumn.Width = Double.NaN; 
     WWPNColumn.DisplayMemberBinding = new Binding("WWPN"); 

     GridViewColumn FCIDColumn = new GridViewColumn(); 
     FCIDColumn.Header = "FCID"; 
     FCIDColumn.Width = Double.NaN; 
     FCIDColumn.DisplayMemberBinding = new Binding("FCID"); 

     GridViewColumn SwitchNameColumn = new GridViewColumn(); 
     SwitchNameColumn.Header = "SwitchName"; 
     SwitchNameColumn.Width = Double.NaN; 
     SwitchNameColumn.DisplayMemberBinding = new Binding("SwitchName"); 

     grid.Columns.Add(FCPortColumn); 
     grid.Columns.Add(WWPNColumn); 
     grid.Columns.Add(FCIDColumn); 
     grid.Columns.Add(SwitchNameColumn); 

     cw.CollectionListView.View = grid; 
     ObservableCollection<PortResult> flogidatabase = new ObservableCollection<PortResult>(); 

     var cs = this.switchList.Where(c => c.switchName == this.ProcessedSwitchesListView.SelectedItem.ToString()); 
     foreach (KeyValuePair<string, FCPort> portpair in cs.FirstOrDefault().FlogiDatabase) 

     { 
      PortResult pr = new PortResult(); 
      pr.WWPN = portpair.Key.ToUpper(); 
      pr.FCPort = portpair.Value.ToString(); 



      pr.FCID = portpair.Value.WWPNList.Where(w => w.WWPNValue == pr.WWPN).Select(t => t.FCIDValue).FirstOrDefault().ToString(); 

      pr.SwitchName = cs.FirstOrDefault().switchName; 
      flogidatabase.Add(pr); 
     } 


     cw.CollectionListView.ItemsSource = flogidatabase; 

     FlogiAddDoubleClickEventStyle(cw, new MouseButtonEventHandler(FlogiDB_MouseDoubleClick)); 
     cw.Show(); 

    } 


private void FlogiDB_MouseDoubleClick(Object sender, EventArgs e) 
    { 


     MessageBox.Show("FlogiDatabase DoubleClick"); 
    }

我已經知道我可以將發件人轉換爲System.Windows.Controls.ListViewItem，但我仍然無法弄清楚如何獲取其中的值。 System.Windows.Forms也有一個包含SubItems的ListViewItem。大多數示例都使用它，但我使用的ListViewItem沒有該屬性。 –

我想出了答案。我需要訪問ListViewItem的DataContext屬性。鑑於從上面的代碼：

ObservableCollection<PortResult> flogidatabase = new ObservableCollection<PortResult>(); 
CollectionWindow cw = new CollectionWindow(this.VirtualFabricList); 
cw.CollectionListView.ItemsSource = flogidatabase;

然後才能到存儲的內容在我們投在DataContext回PortResult每一個ListViewItem：

PortResult pr = ((PortResult)lvi.DataContext);

，然後我們可以訪問一個PortResult屬性。

string wwpn = pr.WWPN;
