问题类似于此处所示:http ://forums.asp.net/t/945656.aspx/1
我有一个带有更新按钮的 gridview 来更新行。
隐藏列时,它会尝试将空值插入数据库并使用空值更新当前数据。我不希望这样,我想保持当前数据不变。
下面是我的sqldatasource
<asp:SqlDataSource ID="sds_OrderDetail" runat="server" ConnectionString="<%$ ConnectionStrings:MyDbConn %>"
DeleteCommand="DELETE FROM [OrderDetail] WHERE [RowNo] = @RowNo" InsertCommand="INSERT INTO [OrderDetail] ([Id], [PONumber], [MaterialCode], [MaterialDescription], [MaterialCategory], [UnitOfMeasure], [Quantity], [ContainerId], [LoadingDate], [CutOffDate], [TransporterName], [BookingNo]) VALUES (@Id, @PONumber, @MaterialCode, @MaterialDescription, @MaterialCategory, @UnitOfMeasure, @Quantity, @ContainerId, @LoadingDate, @CutOffDate, @TransporterName, @BookingNo)"
SelectCommand="SELECT * FROM [OrderDetail] WHERE ([Id] = @Id)" UpdateCommand="UPDATE [OrderDetail] SET [Id] = @Id, [PONumber] = @PONumber, [MaterialCode] = @MaterialCode, [MaterialDescription] = @MaterialDescription, [MaterialCategory] = @MaterialCategory, [UnitOfMeasure] = @UnitOfMeasure, [Quantity] = @Quantity, [ContainerId] = @ContainerId, [LoadingDate] = @LoadingDate, [CutOffDate] = @CutOffDate, [TransporterName] = @TransporterName, [BookingNo] = @BookingNo WHERE [RowNo] = @RowNo"
