title: CommandArgument is empty
body: <p>I would like to do this :</p>
  
  <pre><code>&lt;asp:ImageButton runat="server" ID="addToCartIMG" OnCommand="btnAdd_Click" EnableViewState="false" CommandArgument='&lt;%# itemId1.Value + ";" + Name1.Text %&gt;' ImageUrl="&lt;%$Resources:MasterPage, Image_AddToCart%&gt;" /&gt;
  </code></pre>
  
  <p>where Item1 is hiddenField and Name1 a literal.</p>
  
  <p>When I debug the method btnAdd_Click, the CommandEventArgs is empty and I don't understand why...</p>
  
  <p>Thank you</p>
