title: Multiple values on datatextfield
body: <p>I bind a dropdownlist to the datasource, and defined text and value columns on codebehind.</p>
  
  <pre><code>DropDownList1.DataTextField = "Product_Name"
  DropDownList1.DataValueField = "Product_ID"
  </code></pre>
  
  <p>It works fine. But I want to assign one more column to <code>DataTextField</code>, <code>Order_Date</code>. I tried my chance with this:</p>
  
  <pre><code>DropDownList1.DataTextField = "Product_Name"+"Order_Date"
      DropDownList1.DataValueField = "Product_ID"
  </code></pre>
  
  <p>But it didn't work. Is it possible to show multiple values on <code>DataTextField</code>?</p>
