Jon, I am new to asp.net programming and I also tried the same original 
method you described to try and dynamically pass a variable to a control. 
Could you explain how you resolved this. 
Elissa replied with the following tip:
hlDisplayItemText.NavigateUrl = "theUrlofpageIwant";
which doesn't make sense to me. If I set this within the control how does 
this solve the initial pass. Thanks for your help in advance. Rich

Hi, all!

Jon, you could check out the code I have below. It's pretty basic but the 
thing here is that you can pass off any href value to your asp:hyperlink 
control. Hope this helps!

-------------------------------
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Web.UI.WebControls" %>

<script runat="server">

  Sub submit_link(sender As Object, e As EventArgs)
    Dim linkValue As String
    If Page.IsPostBack Then
      linkValue = Request.Params("linkparam")
      sample1.NavigateUrl = linkValue
     End If
  End Sub

  Sub Page_Load(sender As Object, e As EventArgs)
    If Not Page.IsPostBack Then
      sample1.NavigateUrl=""
    End If
  End Sub

</script>

<form runat="server">
  <asp:textbox id="linkparam" 
               TextMode="SingleLine" 
               width="100" runat="server" />
  <asp:button id="linkbtn" 
              onClick="submit_link" 
              Text="click here" runat="server" /> <br />
  <asp:hyperlink id="sample1" 
                 Text="This is your life!" 
                 NavigateUrl="" runat="server" /> 
</form>

Cheers!
