If you create a hyperlink using asp tags

 <asp:HyperLink  id="aspHyp" runat ="server" ></asp:HyperLink>

Then you can check whether the href is blank or not using

If aspHyp.NavigateUrl = "" Then
   MsgBox("Href is blank!")
End If

If you create a hyperlink using <a>

 <a id="hyp" runat ="server">TEXT</a>

Then you can check whether the href is blank or not using

 If hyp.HRef = "" Then
  MsgBox("Href is blank!")
 End If

in html you can check by this

<%
if (your condition) {%>

tags to show...

    <%} %>

and when you want to do this in code behind, you should use this

 if(hyp.NavigateUrl = "")

{ write your code here .... }

Are you missing " around id="hyp" or was that just a typo?

You should be able to check if the NavigateUrl on a Hyperlink is an empty string, like you're doing.

The URL to navigate to when a hyperlink in a HyperLinkField is clicked. The default is an empty string (""), which indicates that this property is not set.
