DataForm和DataGrid問題

Silverlight系統，其中一個asp用戶藥房有一個鏈接的表對於他們的庫存。我試圖在列表（datagrid）中顯示這個清單，併爲它們提供了一種通過數據網格編輯和添加項目到列表的方法。目前我正在努力與這個數據表的綁定... Xaml提供，任何幫助？DataForm和DataGrid問題

歡迎來到StackOverflow！你能更具體地說明什麼是「與綁定掙扎」的意思。如果沒有清楚地指出你遇到的具體問題，這是很多標記。 –

將數據表單和數據網格專門綁定到已登錄藥房的庫存。我通過過濾器描述符成功地獲得正確的藥房。但是，它似乎將數據表單綁定到藥房的域服務，並且不允許它深入到清單（這是另一個表）。 – user1732039

只需添加...將它們綁定到PharmacyDomainDataSource --- 似乎嘗試在每次調用數據源提交更改（）時創建一個新葯房。與InventoryDomainDataSource的綁定未將其鏈接到所述藥房。 ---- 我試圖通過從InventoryDDS獲取所有數據並將其放入IEnumerable列表中，然後製作Pharmacy.MedInv =列表來解決此問題。然而，這是行不通的。 – user1732039

使用兩套的TextBlocks的，一個編輯/添加創建了自己的定製版本，唯一可見的話，另一個用於觀看。如果有人有興趣，我可以分享代碼。
