title: Textbox next to the RadioButtonList
body: <p>I need to create a radiobuttonlist containing a "other" option, and i have to put a textbox next to it. Here is what i did.      </p>
  
  <pre><code>if(!ispostpage){
  PlaceofWork.DataSource = workplace;
  PlaceofWork.DataBind();
  PlaceofWork.DataTextField = "WorkPlace1";
  PlaceofWork.DataValueField = "WorkID";
  PlaceofWork.Items.Add(new ListItem("Other - Specify&lt;input name=\"OtherWorkPlace\" type=\"text\" value=\"test\" id=\"OtherWorkPlace\"/&gt;", "-1"));
  </code></pre>
  
  <p>This radiobuttonlist is in a usercontrol.
  at the first I didn't add <code>if(!ispostpage)</code> so when i try <code>Request.Form["OtherWorkPlace"]</code>, it didn't return anything</p>
  
  <p>after i add the code <code>if(!ispostpage)</code>, it pop up the error "Object reference not set to an instance of an object"</p>
  
  <p>So how can I get the value of the input textbox?</p>
