This is radbutton
 <telerik:RadButton CssClass="btn btn-success" EnableEmbeddedSkins="false"  RenderMode="Lightweight" Primary="true" ID="RadButton1" runat="server" Text="RadButton"></telerik:RadButton>
This is radradiobuttonlist
   <telerik:RadRadioButtonList ID="radListType" AutoPostBack="true" runat="server">
                  <Items>
                      <telerik:ButtonListItem Selected="true"  Text ="Internal User" Value ="Internal User" />
                        <telerik:ButtonListItem  Text ="External User" Value ="External User" />
                
                  </Items>
                </telerik:RadRadioButtonList>
