title: Call function with parameters via databinding
body: <p>OK Im at a crossroads with something.  Take a gander at the code below.  I have a data repeater, and throughout the repeater I want to call GetNavUrl, supplying it with a parameter found in my data I am binding with.</p>
  
  <pre><code>NavigateUrl='&lt;%# GetNavUrl(DataBinder.Eval(Container.DataItem,"ProductCode") %&gt;'
  </code></pre>
  
  <p>So, for example, I want navigateURL to equal the result of GetNavUrl(123), Any ideas?  thx!</p>
