Answer 1

您需要使用以下方法将 gvContent 注册为异步回发控件

 void Page_Load()
    {
        if (!IsPostBack)
        {
            ScriptManager1.RegisterAsyncPostBackControl(gvContent);
        }

    }

这将导致您的 Grid 执行异步回发。

希望有帮助

尝试添加一个空的 RowDeleting 事件

 protected void gvContent_RowDeleting(object sender, GridViewDeleteEventArgs e)
 {

 }
