GridView：如何在单击超链接字段时传递编码数据

Question

当我尝试在 GridView 的超链接字段中传递编码的 URL 字符串时，如下所示：

<asp:HyperLinkField HeaderText="Customer" DataTextField="Customer" DataNavigateUrlFields="Customer"
    DataNavigateUrlFormatString= "Changes.aspx?customer={0}" SortExpression="Customer"
    NavigateUrl="~/Client.aspx" />

我收到此错误：

只有具有 DataBinding 事件的对象才支持数据绑定表达式。 System.Web.UI.WebControls.HyperLinkField 没有 DataBinding 事件

有什么方法可以在超链接字段中传递编码字符串？

替代方法：

另外，有什么方法可以读取查询字符串中的特殊字符？如果我使用它，我可以读到某个特定的特殊字符吗？

Request.QueryString["customer"]

这是从我在上面发布的 msdn 链接中截取的片段，它将向您展示您需要什么.. 遵循这个示例，它应该适合您.. 更改字段绑定值以匹配您的情况.. 从此链接粘贴的示例MSDN - HyperLinkField.DataNavigateUrlFormatString Property

 <h3>HyperLinkField Example</h3>

      <!-- Populate the Columns collection declaratively. -->
      <!-- The UnitPrice field values are bound to the         -->

      <!-- field column, formatted as currency. The ProductID  -->
      <!-- field values are bound to the navigate URLs of the  -->
      <!-- hyperlinks. However, instead of being the actual    -->
      <!-- URL values, the product ID is passed to the linked  -->
      <!-- page as a parameter in the URL specified by the     -->
      <!-- DataNavigateUrlFormatString property.               -->
