I am creating gridviews using C# and ASP.net ... I need help in creating 2 gridviews which they have same processID and getting data from different SQL tables in the same database..When I click on the one first row of the first gridview it should give me the list of files with the same processID and its details in the second gridview

One process ID has many different xml files stored in it for example processID = 7A413EA4-8ECE-472D-92BE-F58C22E5C567 in the first gridview so all the xml files with the username, date, login date having the same processID in the second table should show up on selecting the row in the first table

This is what I have so far done:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="FS_PS2FS._Default" %>

PS2FS Client                                                                                           


  " SelectCommand="SELECT [LOG_Id], [LOG_FileName], [LOG_Description], [LOG_Date], [LOG_ProcessId], [LOG_Details], [LOG_UserId] FROM [FS_LOG_PS2FS] ORDER BY [LOG_Date] DESC">

</div>
    <asp:SqlDataSource ID="PS2FS_FS" runat="server" ConnectionString="<%$ ConnectionStrings:FreightsmartWebConnection %>"
        SelectCommand="SELECT [P2FV_ID], [P2FV_MessageType], [P2FV_MessageText], [P2FV_FileName], [P2FV_ProcessId], [P2FV_CreateDate], [P2FV_CreateUser] FROM [FS_LOG_PS2FS_Validation] ORDER BY [P2FV_CreateDate] DESC">
    </asp:SqlDataSource>
