I have a FormView and a HyperLink on the page.

If I use the following code behind (hooked up to Hyperlink's OnLoad event),
it renders fine

protected void link_Load(object sender, EventArgs e)
{
link.NavigateUrl = String.Format("~/Carrier/AddNew.aspx?Id={0}",
FormView1.DataKey.Value);
}

However, I was not able to achieve the same goal declaratively, just using
<%# ... %> syntax in .aspx

Where's the catch?

Dmitry

Any of the following renders just text instead of hyperlink:
NavigateUrl='<%# String.Format("~/Carrier/AddNew.aspx?Id={0}",
Eval("FormView1.DataKey.Value")) %>'

NavigateUrl='<%# String.Format("~/Carrier/AddNew.aspx?Id={0}",111) %>'

NavigateUrl='<%# Eval("FormView1.DataKey.Value") %>'

Hi Dmitry,

I've done some test and both of following approaches should work for you:

<asp:HyperLink ID="link1" runat="server" Text="Link" NavigateUrl='<%#
String.Format("~/Carrier/AddNew.aspx?id={0}", Eval("Id"))
%>'></asp:HyperLink>
<br />
<asp:HyperLink ID="link2" runat="server" Text="Link2" NavigateUrl='<%#
String.Format("~/Carrier/AddNew.aspx?id={0}", FormView1.DataKey.Value)
%>'></asp:HyperLink>

The first one is assuming you need to use some field as the id; the second
one is the exact case as yours.

Please feel free to let me know if there's anything I can help.

First one doesn't woudn't since I dont have Id control

> <asp:HyperLink ID="link2" runat="server" Text="Link2" NavigateUrl='<%#
> String.Format("~/Carrier/AddNew.aspx?id={0}", FormView1.DataKey.Value)
> %>'></asp:HyperLink>

Second one "just" doesn't work. It renders text only:
<a id="ctl00_ContentPlaceHolder1_link2">Link2</a>
