Your dropdownlist is enabled with AutoPostBack. So when you select any item, PostBack occurs and Page_Load event will trigger.

Check in Page_Load event, whether dropdownlist binding code is outside IsPostBack check. If so on each Selection on Dropdownlist, dropdownlist will get rebind and lost its selection.
Page_Load Event
If (!IsPostBack)
{
 // Dropdownlist Bind Code should be here
}

Open in new window


Just verify this case
