How do I refer to <%# Eval('column')%> in a .aspx scripting tag?

Question

Please note that I am using a SQLDATASOURCE to perform a SELECT * FROM myTable. Here is a small piece of the item template of my repeater:

<li>Work Extension: <%# Eval("WK_PHONE_EXT")%></li>

Now, lets say that <%# Eval("WK_PHONE_EXT")%> is an empty string. How do I go about referencing <%# Eval("WK_PHONE_EXT")%> in a <script language="c#" runat="server"> tag. I know i can do it from the codebehind, by placing the value of the EVAL tag in an asp:label text property then finding it. Im just looking for a shorter way to say:

if(<%# Eval("WK_PHONE_EXT")%> == ""){
<%# Eval("WK_PHONE_EXT")%> == "N/A";
}

So I do not have to rebuild my simple DNN Module. Is something like this possible?

You could check inline

   <%#(String.IsNullOrEmpty(Eval("WK_PHONE_EXT").ToString()) ? "N/A" : Eval("WK_PHONE_EXT"))%>

EDIT:

For complex conditions, I'd prefer to write a public (or protected) method in the codebehind & handle them there

In UI.. '<%# MyDataItem(Eval("item")) %>'

public string MyDataItem(object value)
{
  if (string.IsNullOrEmpty(value.ToString()))
  {
     return "N/A";
  }

  return myValue.ToString();
}
