У меня есть несколько связанных полей, но они, похоже, не устанавливают параметры UpdateParameters для моего оператора SQL.У меня есть некоторый код, который запускается в SqlDataSource Update, чтобы установить UpdateParameters для несвязанных полей, поэтому я не уверен, что это вызывает проблему.
Я вставил свой код ниже.
