Use the property AppendDataBoundItems

<asp:dropdownlist runat="server" id="ddlProfRole" width="87%" datavaluefield="ProfRoleCode" datasourceid="SqlDataSource2" datatextfield="ProfRoleDescription" appenddatabounditems="true" xmlns:asp="#unknown">
    <asp:listitem text="ALL" value="" />   
</asp:dropdownlist>
