ASCX - Function Not Being Called

[George Durzi]

I created a simple user control which contains a hyperlink to link the user
to a topic in a compiled help file. I named all my help topics to have the
same name as the aspx they are for.

So in the user control help.ascx's html, I have this:
<a href='<%# GenerateHelpLin k()%>' class="mischref content2" id="hrfHelp"
runat="server" target="_blank" >Help</a>

In the codebehind help.ascx.cs, I have this:
#region GenerateHelpLin k
protected void GenerateHelpLin k()
{
StringBuilder sb = new StringBuilder() ;
sb.Append("ms-its:");

sb.Append(Confi gurationSetting s.AppSettings["ApplicationURL "].ToString());
sb.Append(Confi gurationSetting s.AppSettings["HelpFile"].ToString());
string[] arScript =
Request.ServerV ariables["SCRIPT_NAM E"].ToString().Spl it("/".ToCharArray() );
string sScript = arScript[arScript.GetUpp erBound(0)].ToString();
sb.Append(sScri pt.Substring(0, sScript.LastInd exOf(".")));
sb.Append(".htm ");

// you can ignore these details - this function simply returns a help
URL

return sb.ToString();
}
#endregion

So if I'm at cs_completed.as px, the above function will return:
ms-its:http://gdurzi/framework/help/MyFelpF..._completed.htm

In cs_completed.as px, I do this:
<%@ Register TagPrefix="fram ework" TagName="help" Src="ascx\help. ascx" %>
and
<framework:he lp id="_help" runat="server"> </framework:help>

The text Help (what's inside the <a></a>) is displayed, but the hyperlink
doesn't work. Upon debugging, I realized the function GenerateHelpLin k is
never being called ...

I want to accomplish this without having to write code into every page to
call this function. I just wanted to plop the user control in there and let
it do it's work.. Any idea?

Re: ASCX - Function Not Being Called

Instead of using an <a> tag, I would use a Hyperlink control.

Then in page_load do something like:

Hyperlink1.Navi gationURL = GenerateHelp();

Re: ASCX - Function Not Being Called

I would have to put code in the Page_Load of every ASPX page in my
application. I am trying to avoid that.

Any idea why the GenerateHelpLin k() function doesn't get called though? It
doesn't make a diff if I use an <a> or a <asp:hyperlin k>

Re: ASCX - Function Not Being Called

No, you would need to put this code into Page_Load of the user control, not
the page.

I don't think the <%# %> tags work that way if it's not part of databinding
code. If you did something like <% Response.Write( GenerateHelp()) ; %> that
would probably do it.

But this is doing it the old fashioned ASP way. I think putting all this
type of code into Page_Load is a much neater way to do it. It follows the
idea of separating UI and code that ASP.NET introduces.

Re: ASCX - Function Not Being Called

Thank you, that worked. For some reason I thought the Page_Load event of the
user control wouldn't fire.
