title: Asp.net Dropdownlist : Want to hide the initial value when page loaded for second time
body: <p>I created a dropdown list and then added items to it with an initial value of -1 with text "select country"</p>
  
  <p>My question is: when I select something from the list and later on change my mind to one item to another item. Now I wanted to hide the initial value "select country" from the list on postback</p>
