Question

我有一个包含多个数据项的formview，除了一个不会与其余参数一起更新的参数外，它们的工作方式都很完美。 formview的datasource updateparameter设置为什么都不做，以便我可以在代码隐藏中处理更新。除了在formview的ItemUpdating事件的OldValues和NewValues参数中缺少一个参数（“salesprice”）之外，每个项目都可以正常工作。数据应该正确地插入到文本框中，格式正确且全部。

我附加了html，SQL（用于getLoanData（））和代码隐藏。

为什么除了“salesprice”参数之外，New / OldValue参数中是否存在每个参数？我已经尝试在没有formatstring的情况下填充文本框，但它仍然缺失。是否存在可能导致问题的资金SQL数据类型？

您是否尝试过其他格式字符串？

Text='<%# Bind("salesprice", "{0:C}") %>'

ItemUpdating NewValues缺少参数
