title: loading input from multi choice
body: <p>Hi I have a task as that
  a dropdown list to choose an input type 
  selections are  </p>
  
  <ul>
  <li>textbox</li>
  <li>datetime</li>
  <li>number</li>
  </ul>
  
  <p>while choosing one of those types, I have to open the selected input(for example if user chose datetime I have to open a datetime input) </p>
  
  <p>For this task which is most suitable </p>
  
  <ol>
  <li>using aspview(each input type one view)</li>
  <li>for each one a usercontrol so when user select
  a type loading it's usercontrol at runtime</li>
  </ol>
