hyperlink and dynamically formed NavigateURL problem

[Tomek R.]

Hello !

This post does'nt regard column hyperlink.
I just have single hyperlink and want to create it's NavigateUrl
dynamically.

This is my test page

<form id="Form1" method="post" runat="server">
<asp:HyperLin k id="MyHLink" NavigateUrl='<% # geturl("123456" ) %>'
style="Z-INDEX: 101; LEFT: 280px; POSITION: absolute; TOP: 56px"
runat="server" >MyHLink</asp:HyperLink>
</form>

and my class behind

public class WebForm1 : System.Web.UI.P age
{
protected System.Web.UI.W ebControls.Hype rLink MyHLink;
private void Page_Load(objec t sender, System.EventArg s e)
{
// Put user code to initialize the page here
//this.MyHLink.Na vigateUrl = MyString();
}
#region Web Form Designer generated code
override protected void OnInit(EventArg s e)
{
InitializeCompo nent();
base.OnInit(e);
}

private void InitializeCompo nent()
{
this.Load += new System.EventHan dler(this.Page_ Load);
}
#endregion
protected string geturl(string s)
{ return "www.mypage .com "+s; }
}

Resulting page includes hyperlink, but inactive - not href tag attached. The
syntax is O'K, I believe (no errors on page load).
I've spent a couple of hours for browsing the newsgroups but haven't find
working solution for HTML designing.
What means, I can do this but only when setting NavigateUrl in Page_Load
like this:

private void Page_Load(objec t sender, System.EventArg s e)
{
MyHLink.Navigat eUrl = geturl("123456" );
}

No matter what kind of Url I put (absolute, relative) - Page_Load works
every time.

The only reason I can think about, is that one: geturl and class-behind is
not accessible, when hyperlink is rendered based on design values.
Am I right ?
If yes, how about datagrid and TemplateItem column with hyperlink. In that
case settings like above work perfectly. What is the differences between
datagrid column and hyperlink on page ?

instead of doing NavigateUrl='<% # geturl("12345") %>' do NavigateUrl='<% =
getUrl("12345") %>'

<%# is for databinding, you aren'd databinding and therefore need touse <%=

doing it form your Page_Load, ala:
MyHLink.Navigat eUrl = geturl("123456" );

should work (And is how you should do it, no clumsy method calls in your
presentation), but if you still had the <%# in there, dunno how that would
behave...

Thanks for reply.

<%# is for databinding, you aren'd databinding and therefore need touse

<%=
Yeah, I found some posts with this info, but <%= doesn't work. The resulting
link is the whole phrase, inlcuding <% .

Ya, was being an idiot when I just woke up :)

The correct way to go, as I originally said, is via the Page_Load and doing
MyHLink.Navigat eUrl = geturl("123456" );

if you are certain Page_Load is running, and you don' thave NavigateUrl set
to anything in the HTML (don't even specifiy the problem), it should work.
