Put Link in dynamic .Net Gridview

I'm trying to populate a grid with a list of files that are in a folder.  I'm able to do that fine, but can't figure out how to pass a hyper link into my gridview.  It keeps coming out literally.

Code attached.  Here's the line that I need to change:
row["Link"] = "<a href=metadata.aspx?file=" + fi.Name + ">Add Track Info</a>";

// Detect the user, then check their folder for new tracks
        DirectoryInfo di = new DirectoryInfo("C:\\FTP\\Catalog_DropFolder\\" + Profile.UserName);
        FileInfo[] rgFiles = di.GetFiles("*.wav");
        foreach(FileInfo fi in rgFiles)
        {
            row = dtFiles.NewRow();
            row["FileName"] = fi.Name;
            row["Link"] = "<a href=metadata.aspx?file=" + fi.Name + ">Add Track Info</a>";
            dtFiles.Rows.Add(row);
        }
