title: Adding Item to DataBound Drop Down List
body: <p>Yes, I have read most of the topics here, but I can't find an answer that works.</p>
  
  <p>I have Three drop-down lists. The first is databound to grab distinct experiment names. The user selects, page posts back, and the second drop-down menu displays distinct time points. This is where I need help. I need to add an item to THAT drop-down list whose ID, DataTextField, DataValueField are all TimePt.</p>
  
  <p>Seems simple, but I can't get it to work.</p>
  
  <pre><code>protected void Page_Load(object sender, EventArgs e)
          {
              if (Page.IsPostBack)
              {
                  TimePt.DataSource = TimePTDD;
                  TimePt.DataValueField = "TimePt";
                  TimePt.DataTextField = "TimePt";
                  TimePt.DataBind();
                  TimePt.Items.Insert(0, new ListItem("--Select---", "0"));
                  TimePt.SelectedIndex = 0;
              }
          }
  </code></pre>
  
  <p>I'm missing sometthing.</p>
