Somehow I can not make this expression correctly, may be someone can help?

I have currently

  <%# (DataBinder.Eval(Container.DataItem, "SpouseID").ToString() != "") 
? Eval("SpouseID", "<a href=\"javascript:void(0)\" 
onClick=\"openPeopleID('{0}')\">Spouse's Information</a>") : 
"<a href=\"javascript:void(0)\" onClick=\"openCreateID('motherName','AddressInfoRegular')\">
Enter Spouse's Info first</a>"%></span>

It works correctly if SpouseID is null, e.g. it goes to the Enter case. However, it doesn't work for the case it's a 0.

Is there a simple check for both "0" and ""? Or how to implement null coalesce operator for this complex case?

Thanks a lot in advance.
