在锚标记中使用服务器标记

Question

I would like to use a property ID value in the anchor tag as below:

<a id="aExample" href="/test/example.aspx?id=<%# Id %>" runat="server">Example</a>

But when the page is rendered instead of getting the href as "/test/example.aspx?id=5" i am getting "/test/example.aspx?id=<%# Id %>" as plain text assigned as href of the anchor.

Id = is a property defined in code behind.

Can anybody help me whats wrong with this? NB: I need runat="server"` to be present.

My tag is not inside any Grid view control but within a user control. <%=

Answer 1

Try this,

if you want get variable value from your .cs so you can use. Declare variable in your page. .cs page

 public int Id = 0;

aspx page

<a id="aExample" href="/test/example.aspx?id=<%= Id %>" runat="server">Example</a>

and your a tag is inside in gridview control so you can use like...

<a id="aExample" href="/test/example.aspx?id=<%#Eval("Id")%>" runat="server">Example</a>

Answer 2

Try this

<a id="aExample" href='<%= CompleteURL %>' runat="server">Example</a>

If you can build and bind the complete URL in your property (code behind). I think this can be optimal solution. This way you can also change your URL dynamically.

Answer 3

也许你可以试试这个

<asp:HyperLink ID="aExample" runat="server" NavigateUrl='<%# String.Format("/test/example.aspx?id={0}", Eval("Id")) %>'>Example</asp:HyperLink>

Answer 4

你可以在后面的代码中执行此操作（如果它不在Gridview内或其他类似的控件中）

aExample.Href = "/test/example.aspx?id="+ YourEntity.Id;

Answer 5

You can also set the href of anchor tag in CodeBehind .

CodeBehind:

int Id = 4;
aExample.HRef = "/test/example.aspx?id=" + Id;

Thanks

<a id="aExample" href='<%# string.Format("/test/example.aspx?id={0}", Id) %>'  runat="server">Example</a>
