I have a grid of 100 records.
It is in Div and height limited to 400px, a vertical scroll bar scrolls the whole grid up and down.

the HTML markup is like below...

<div id="dvClinicLookup"  runat="server" style="border: ridge 2px silver; border-radius: 5px;
                                    width: 99%; height: 191px; display: none">
                                    <table border="0">
                                        <tr>
                                            <td style="width: 26%">
                                                <font face="tahoma" size="2" color="black">Enter Keywords to search</font>
                                            </td>
                                            <td>
                                                <asp:TextBox ID="txtClinicKeywords" runat="server" Width="50%">
                                                <asp:Button ID="btnFind" runat="server" Text="Find" />
                                            </td>
                                        </tr>
                                        <tr>
                                            <td colspan="2">
                                                <div id="dv"  runat="server" style="overflow-y: scroll; height: 156px; border: solid 1px silver;">

                                                        </columns>
                                                    
                                                    <asp:SqlDataSource ID="dsAllClinics" runat="server" ConnectionString="<%$ ConnectionStrings:medix_HISDB %>"
                                                        SelectCommand="[spGetAllClinics]" SelectCommandType="StoredProcedure">
                                                        <SelectParameters>
                                                            <asp:SessionParameter Name="ClinicName" SessionField="ClinicName" Type="String" />
                                                        </SelectParameters>
                                                    
                                                
                                            </td>
                                        </tr>
                                    </table>

Now, I want to give a rowindex and gridview should scrolls down to that row.
Javascript assistance is appreciated..

Thanks & Regards
