title: Usercontrol within a usercontrol
body: <p>I have a UserControl1 within a UserControl2. The first UserControl1 has a RadioButtonList on it with multiple radio button when clicked causes a postback and does it work. In UserControl2 i have a html textarea  with runat="server" attribute with a save button.</p>
  
  <p>Then I am using UserControl2 on a page.</p>
  
  <p>Issue : When the user is writing some text in the textarea(UserControl2) and in between when he tries to click anyone of the Radiobutton(from UserControl1) the page is posted back and the text value of the textarea is lost. I have also enable viewstate for the textarea.</p>
  
  <p>Please guide me. How can I save the value of the textarea when the user clicks a radio button.</p>
