title: How to create the wizard-like ui in .net
body: <p>I have to build the wizard-like ui since the operation should be done through 3 steps.</p>
  
  <p>And in each step user will input some fields,then when he hit the next,I will check the current input,if valid,I will to to next wizard.</p>
  
  <p>If there are input invalid,he will be left to current wizard.</p>
  
  <p>That's to say,each time the user hit the next button,form will be submitted to server.</p>
  
  <p>And when user hit the prev button,the content input before should be kept.</p>
  
  <p>I do not have a good solution for this manner.</p>
  
  <p>Any one can give me some suggestion?</p>
