下拉列表框作爲DataGrid中的EditTemplate - 不綁定

我不知道該綁定網格視圖的編輯模板中使用的下拉列表。我得到的錯誤是「附加信息：DataBinding：'System.Data.DataRowView'不包含名稱爲'Type'的屬性。」下面是來自網格視圖的摘錄...下拉列表框作爲DataGrid中的EditTemplate - 不綁定

看起來你收到此錯誤，因爲你的選擇查詢不包括類型字段。如果你修改你的查詢，我認爲它會工作得很好。請注意，在FROM關鍵字前添加了[tbl_Lease_Agrmnt]。[Type]。

SELECT [tbl_Lease_Agrmnt].[LeaseAgrmntID], [tbl_Lease_Agrmnt].[SalesOrderID], [tbl_Lease_Agrmnt].[SerialNo], [tlkp_Lookup_Values].[Code], [tbl_Lease_Agrmnt].[ContractNo], [tbl_Lease_Agrmnt].[ScheduleNo], [tbl_Lease_Agrmnt].[StartDate], [tbl_Lease_Agrmnt].[Term], [tbl_Lease_Agrmnt].[Hours], [tbl_Lease_Agrmnt].[Rate], [tbl_Lease_Agrmnt].[ReturnDate], [tbl_Lease_Agrmnt].[CloseDate], [tbl_Lease_Agrmnt].[ExtensionStartDate], [tbl_Lease_Agrmnt].[ExtensionTerm], [tbl_Lease_Agrmnt].[Type] FROM [tbl_Lease_Agrmnt] LEFT JOIN [tlkp_Lookup_Values] ON [tbl_Lease_Agrmnt].[Type] = [tlkp_Lookup_Values].[LookupValuesID] WHERE ([SalesOrderID] = @SalesOrderID) ORDER BY [LeaseAgrmntID]

當我添加字段時出現以下錯誤...'ddlTypeEdit'具有無效的SelectedValue，因爲它不存在於項目列表中。參數名稱：值 – Rodd

如果將SelectedValue ='<％＃綁定（「代碼」）％>'更改爲SelectedValue =「Code」，會怎麼樣？ –
