HyperLink with NavigateUrl with Eval(). Where is the mistake?
提问by abatishchev
First I was changing HyperLink.NavigateUrlin code-behind on Page_Load().
首先，我HyperLink.NavigateUrl在Page_Load().
But after I decided to do it in design using Eval()method.
但是在我决定在设计中使用Eval()方法之后。
<asp:HyperLink runat="server"
NavigateUrl='<%# String.Format("~/Refuse.aspx?type={0}&id={1}", Eval("type"), Eval("id")) %>' Text="Refuse" />
or
或者
<asp:HyperLink ID="urlRefuse" runat="server"
NavigateUrl='<%# String.Format("~/Refuse.aspx?type={0}&id={1}", Request["type"], Request["id"]) %>' Text="Refuse" />
where idand type- are variables from Request.
其中id和type- 是来自 的变量Request。
But it doesn't work. Only raw text 'Refuse' is shown. Where is my mistake? Thanks in advance.
但它不起作用。仅显示原始文本“拒绝”。我的错误在哪里？提前致谢。

this is working great
这很好用
NavigateUrl='<%# Eval("type","~/Refuse.aspx?type={0}") %>'

Try and ViewSource in your browser, what's being rendered to the client in your href? Is it what you expected?. If you are trying to use variables from the request collection you can't use Eval, you need to use the Request query string parameters.
在浏览器中尝试 ViewSource，在您的 href 中向客户端呈现什么？是你所期待的吗？。如果您尝试使用无法使用 Eval 的请求集合中的变量，则需要使用请求查询字符串参数。
<asp:HyperLink runat="server"
NavigateUrl='<%# String.Format("~/Refuse.aspx?type={0}&id={1}", Request["type"], Request["id"]) %>' Text="Refuse" />
