  <asp:DropDownList ID="ddl_country" runat="server" CssClass="DropDownList"></asp:DropDownList>                                                               
  <cc1:CascadingDropDown ID="cdd_country" runat="server" category="ParentCat" loadingtext="loading..." promptvalue="Select a country" servicemethod="GetParentCategory"                                                                    servicepath="/webservices/area.asmx" targetcontrolid="ddl_country">

  You have not provided enough code. 

  This best we can do for you is provide blogs and tutorials that explain how to implement the CascadingDropDown.  Please set aside time to learn how to use the CascadingDropDown control.
