I cannot assign javascript function only when there is an attachment

Question

I have that code:

<strong><a <%# Eval("DsPathDocumento") != null && !String.IsNullOrEmpty(Eval("DsPathDocumento").ToString()) ? String.Concat("href='/UpLoads/", Eval("DsPathDocumento"), "'") : "style='cursor: default; color:#000000;'" %>>
                        <%# Eval("NmTipoDocumento")%>
                    </a></strong>

I happen to need to apply a javascript, through this class: class="linkUpload" This class can only happen when I create the hyperlink, otherwise the class cannot be called. My whole attempt to put this class didn’t work. If I put it right after the, like,: <strong><a class="linkUpload" <%# Eval("DsPathDocumento") != null && ...</a></strong>, when I have document it calls the popup, ok, correct and when I have no link, it also calls the blank popup. He always mounts href, even without attached document, as I discussed here at SOPT. Below my javascript:

$(document).ready(function () {
        $('.linkUpload').click(function (event) {
            event.preventDefault();
            window.open($(this).attr("href"), "popupWindow", "scrollbars=yes");
        });
    });

The question is: How do I assign javascript to the class only when there is an attached document.

So: If I have attached document, the ternary expression above in the post, must perform the step after the symbol "?" and if there is no attachment, then perform the step after the ":", right? Well, it turns out that anyway and I don’t know why, he’s creating the underline referring to href even when there’s no attachment. I have the "linkUpload" class that should be executed only when there is an attachment. If I put this class right after the "a" tag, it is valid for all situations in the ternary expression, that is, with or without an attachment and I can’t call an expression or html command from within the Asp.Net tags, then generated the post: How do I assign the function only when there is link, ie only when the first part of the ternary expression is executed.

What I want is this, or something similar. I have this Asp.net tag: <% %>. What would I call this class: class="linkUpload" within the Asp.net tag?

I tried to do an if to suit better, I think, and I’m not getting it. I tried it in several ways and this way was the last attempt before this post.

<%if(Eval("DsPathDocumento") != null && !String.IsNullOrEmpty(Eval("DsPathDocumento").ToString()))
                      { %>
                      <strong><a class="linkUpload" 
                      <% String.Concat("href='/UpLoads/", Eval("DsPathDocumento"), "'") %>>
                      </a></strong> <%}%>
                      <%else
                      { %>                      
                      "style='cursor: default; color:#000000;'"
                      Eval("NmTipoDocumento")
                      <%}%>

I switched to that shape and made the following mistake:

<% if(Eval("DsPathDocumento") != null && !String.IsNullOrEmpty(Eval("DsPathDocumento").ToString()))
                      {%>
                      <strong><a class="linkUpload" 
                      <% String.Concat("href='/UpLoads/", Eval("DsPathDocumento"), "'"); %>>
                      </a></strong> <%}%>
                      <%else
                      { %>                      
                      <"style='cursor: default; color:#000000;'">
                      Eval("NmTipoDocumento")
                      <%}%>

That is the mistake:

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

It works?

<strong>
  <a <%# 
    Eval("DsPathDocumento") != null && !String.IsNullOrEmpty(Eval("DsPathDocumento").ToString()) 
        ? String.Concat("href='/UpLoads/", Eval("DsPathDocumento"), "'") 
        : "style='cursor: default; color:#000000;'" %>>
    <%# Eval("NmTipoDocumento")%>
  </a>
</strong>

Then it would just be add class="linkUpload" after the href in its element a, would look like this:

<strong>
  <a <%# 
    Eval("DsPathDocumento") != null && !String.IsNullOrEmpty(Eval("DsPathDocumento").ToString()) 
        ? String.Concat("href='/UpLoads/", Eval("DsPathDocumento"), "'", " class='linkUpload'") 
        : "style='cursor: default; color:#000000;'" %>>
    <%# Eval("NmTipoDocumento")%>
  </a>
