                       <asp:Label ID="lbEventID" runat="server"
       Text='<%# Eval("event_id") %>' Visible="true" />
      <asp:Label ID="CompanycodeLabel" runat="server"
       Text='<%# Eval("event_id") %>' Visible="False" />
                       </td>
                       <td><%# Eval("end_date", "{0:dd-MM-yyyy}") ?? "&nbsp;"%></td>
                                         <td>

    <asp:Button ID="SelectButton"  class="selectButton" runat="server"  CommandName="Select" />
