title: Data Reset on Rotation in Android/Monodroid
body: <p>I have a text field which indicates date selected by the user.Also i have provided a button for the user to change the currect date.
  The problem i am facing is as follows.</p>
  
  <p>1 . In the Oncreate method i have set the textfield to the current date.When the activity gets created it displays the current date.</p>
  
  <ol>
  <li>I use the button and change the date to someother date.</li>
  </ol>
  
  <p>All this works fine..</p>
  
  <p>But when i rotate the device the oncreate again gets called and textfield gets changed to the current one. I want the textfield to retain the user selected one.</p>
  
  <p>Please help me in this issue. Is there any way to prevent this ?</p>
