title: textboxes reads empty string ("") when i press submit button!
body: <p>I have a form , with 5 textboxes, 1 radiobutton group (4 radiobuttons) , and a submit button, 
  i added some "code behind" to handle cases where a user doesnt fill in all the fields,</p>
  
  <p>something like </p>
  
  <pre><code> if (question.Value == "") // question = a textbox with runat=server property
  {
    // handle error
  }
  </code></pre>
  
  <p>the problem is that, the 1st time i fill the form,and click submit, it always sends empty values :S
  in other words. the above snippet of code will always be true :S
  can some1 explain to me where did i go wrong ? </p>
  
  <p>note: if the same question been asked before.. please link me..</p>
