title: Combining mulitple fields in ASP.NET Dynamic Data foreign key display
body: <p>I have two tables (Person and Location)</p>
  
  <p>In the Dynamic Data Site, when adding Location info, I am need to choose a person from the dropdown box which is populated via a FK.  That dropdown box defaults to the field in "Person" that is titled "fname" which is first name, so it looks like "Jim" or "Steve".</p>
  
  <p>I'm trying to have that dropdown box display the full name of the person it references which would be combining the fields fname and lname.</p>
  
  <p>Would I do this inside a Field Template? Metadata?  I'm kind of stuck on this.</p>
  
  <p>If I look at the FieldTemplate for ForeignKey_Edit I see this:</p>
  
  <pre><code> protected void Page_Load(object sender, EventArgs e)
      {
          if (DropDownList1.Items.Count == 0)
          {
              if (Mode == DataBoundControlMode.Insert || !Column.IsRequired)
              {
                  DropDownList1.Items.Add(new ListItem("[Not Set]", ""));
              }
              PopulateListControl(DropDownList1);
          }
  
          SetUpValidator(RequiredFieldValidator1);
          SetUpValidator(DynamicValidator1);
      }
  </code></pre>
  
  <p>and it seems like I should be able to make something similar to "PopulateListControl" and use that instead, but I have no idea where this method even resides.  </p>
  
  <p>Any ideas?</p>
