Combining Strings in ASP.NET Attributes

Question

I am trying to concat a string inside the attribute. I get an error. I think that it is related to my Eval. Is there a proper way to concat strings, or is this

Here's what I do when I have something in a gridview like this:

[CS code-behind]

public string GetDisImageLink(string dis)
{
    return "../../Content/Images/CardContactInfo/" + 
       (dis.Trim() == "Y" ? "DIS.png" : "Blank.png");
}
