Question

我不知道绑定网格视图编辑模板中使用的下拉列表的对象。我得到的错误是＆＃34;附加信息：DataBinding：＆＃39; System.Data.DataRowView＆＃39;不包含名称为＆＃39; Type＆＃39;的属性。＆＃34;以下是网格视图的摘录...

看起来您收到此错误，因为您的选择查询不包含类型字段。如果您修改您的查询，我认为它将正常工作。请注意在FROM关键字之前添加 [tbl_Lease_Agrmnt]。[类型] 。

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]

下拉列表框作为DataGrid中的编辑模板 - 不绑定
