Question

我有一个SqlDataSource附加到FormView，用于插入/更新，它曾经完美地工作 - 但现在突然间，没有任何参数被插入到行中（该行仍然创建有错误，但除了ID之外的所有字段都是null。我已仔细检查以确保所有正确的文本框都绑定到列名称，并且它们是。

我只是想知道什么样的问题会导致这种情况，因为我很难过。我已经附加到formview的DataBound方法只是为了确保表单不会在回发时被反弹而事实并非如此。我还检查了Inserting方法，参数都是null。

编辑：这是数据源标记：

Answer 1

在INSERT命令中，我看不到ID：

INSERT INTO Orders(Customer, Collection, SalesPerson, Offload, Status, ContactID,
OrderNumber, QuoteNumber, ProjectDetails, SalesPersonContact, DeliveryCharge) VALUES
(@Customer, @Collection, @SalesPerson, @Offload, 1, @ContactID, @OrderNumber, @QuoteNumber, 
@ProjectDetails, @SalesPersonContact, @DeliveryCharge);

插入/更新时SqlDataSource参数为null
