Solution(Use TABLE to layout, do not put anything after TextBox – even &nbsp;)

<table>   
        <tr>    
         <td>    
                  Search by<asp:TextBox ID="txtSearchById" runat="server" autocomplete="off" ></asp:TextBox>        </td>   
        <td>    
             <asp:Button ID="btnSearchById" runat="server"  Text="Search"  Height="23px"  OnClick="btnSearchById_Click" />    
         </td>    
      </tr>    
 </table> <ajaxToolkit:AutoCompleteExtender runat="server" ID="DistrictID_autoComplete" TargetCnotallow="txtSearchByID"  
            ServicePath="DAutoComplete.asmx" ServiceMethod="GetIDCompletionList"  
            MinimumPrefixLength="2" Completinotallow="500" Completinotallow="20"    >
