title: DropDownList - Retrieving Data from Database - Disappear After AutoPostBack
body: <p>My <code>DropDownList1</code> retrieves a data from a column in the database, on the same page, I have another <code>DropDownList2</code>  that when Selecting a value, it will fire an <code>AutoPostBack</code>, the problem I am running into is, </p>
  
  <p>if I select a value from <code>DropDownList1</code>, the value will be un-selected when the <code>AutoPostBack</code> happens, how can I make the <code>DropDownList</code> keeps the selected Value when an <code>AutoPostBack</code> is fired?</p>
  
  <p>Thank you</p>
