Question

我面临一种奇怪的问题。

问题：

当我点击网格视图中的链接按钮时，在 localhost 上部署时，网格视图的 RowCommand 事件被解雇但是不是在 IIS 即客户端系统上部署时。我也在网格视图中尝试了一个链接按钮，但也没有被解雇。

解决方案：（临时）

当我在.aspx页面顶部禁用 ValidateRequest 时。工作。

我该怎么办？ 那么可能的解决方案是什么呢？我用Google搜索了，但没有任何好处。

代码：

Answer 1

如果设置ValidateRequest = false解决问题，听起来您的网页正在尝试提交它认为有潜在危险的内容。您页面上的某个控件是否可能正在发送html或类似内容？

如果您的某个控件需要发送HTML，那么您可以通过向模型添加属性来克服此问题。

 [AllowHtml]
 [Required]
 public string article_content { get; set; }

这将允许将html输入控件。

为什么Gridcom的Rowcommand事件没有被解雇？
