title: Web Forms 4.5 - Repeater.Items is empty on Postback
body: <p>I have a Repeater which has it's data set up on Page_Load</p>
  
  <pre><code>protected void Page_Load(object sender, EventArgs e)
  {
              if (!Page.IsPostBack)
              {
                   myRepeater.DataSource = data;
                   myRepeater.DataBind();
               }
  }
  </code></pre>
  
  <p>When I come to save my data on postback, myRepeater.Items contains zero elements when I know there are several.</p>
  
  <pre><code>    protected void btnSave_Click(object sender, EventArgs e) 
      {
  
          ....
          // why does this contain zero elements&gt;
          foreach (RepeaterItem item in myRepeater.Items)
          {
  </code></pre>
  
  <p>Any suggestions as to what may be the issue?</p>
