title: Text in UserControl TextBox disappear after click on a button
body: <p>Good day, </p>
  
  <p>I have a aspx page name MakeRedemption.aspx.</p>
  
  <p>Inside this MakeRedemption.aspx, I have a UserControl page name SearchGift.ascx. </p>
  
  <p>Inside SearchGift.ascx, I have a repeater. Inside this repeater, I have another UserControl page name InfoForm.ascx.</p>
  
  <p>Which is means, SearchGift.ascx contain a UserControl page name InfoForm.ascx.</p>
  
  <p>InfoForm.ascx have some textboX to let user key in value.</p>
  
  <p>But, after I key in those value, and click on a button in SearchGift.ascx, InfoForm.ascx seen post back and those value gone. Thus, I cant get any value that I key in early.</p>
  
  <p>I also not sure which part of code I should post here. Hopefully my sentences here can describe my problem clearly.</p>
  
  <p>Kindly Let me know if my question is not clear.</p>
  
  <p>Regards.</p>
