title: Data are missing after updating
body: <p>Okay I'll discuss my problem with images so we can solve it easily. Hoping.</p>
  
  <p>First, The image below shows the PersonalInfo gridview under PersonalInfo.aspx
  <img src="https://i.stack.imgur.com/4TIWj.jpg" alt="enter image description here"></p>
  
  <p>Second, The image below shows the MobileInfo gridview under MobileINfo.aspx<img src="https://i.stack.imgur.com/TKaM9.jpg" alt="enter image description here"></p>
  
  <p>Third, now we are going to edit the record in this page MobileInfo.aspx<img src="https://i.stack.imgur.com/kOjg2.jpg" alt="enter image description here"></p>
  
  <p>Fourth, Image below I thought everything works perfectly because the data has been updated. But...<img src="https://i.stack.imgur.com/7REtS.jpg" alt="enter image description here"></p>
  
  <p>Fifth and last, I went back in PersonalInfo.aspx but it gives me this...Data has been deleted<img src="https://i.stack.imgur.com/V7m2V.jpg" alt="enter image description here"></p>
  
  <p>Here's my code for PersonalInfo.aspx</p>
