C＃Visual Studio：如何在不激活其他字段验证器的情况下更新GridView？

Question

Hey guys, I have a GridView and I'm trying to use an event (GridView1_RowUpdated) to tell the user that the update was successful but every time i try to update the row the field validators of the other text input fields are activated. 大家好，我有一个GridView，并且尝试使用事件（GridView1_RowUpdated）告诉用户更新成功，但是每次我尝试更新该行时，都会激活其他文本输入字段的字段验证器。 What I want to know is how can I stop that? 我想知道的是我该如何阻止呢？

使用CausesValidation阻止其运行验证器：

<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" CausesValidation="False" />
