asp.net show selected gridview data in 2nd area on page

Hi Experts,

I currently have a gridview that shows information from a db2 database, the SQL is a little messy but given how I have been asked to pull the data it works and will be refined shortly..

The new requriement is that the data is selectable and the selected data shows in a second area.

The way this has been laid out in the spec shows that is must not be a second gridview, but more a table with textfields

the code used to bind the data to the gridview is

 txtSuName.Text = txtSuName.Text.ToUpper
        'If txtSuName.Text.Length = 0 And txtSupNo.Text.Length = 0 And drp20.SelectedValue = "" And drp21.SelectedValue = "" And drp22.SelectedValue = "" And drp23.SelectedValue = "" And drp23.SelectedValue = "" Then
        If txtSuName.Text.Length = 0 And drp20.SelectedValue = "" And drp21.SelectedValue = "" And drp22.SelectedValue = "" Then
            Exit Sub

        End If

        Dim supNo, supName, cat20, cat21, cat22 As String
        If rdoSupName.SelectedValue = "Name" Then
            If txtSuName.Text = Nothing Then
                supName = Nothing
            Else
                supName = "and a.ABALPH like '%" & txtSuName.Text & "%'"
            End If
        End If

        If rdoSupName.SelectedValue = "Number" Then
            If txtSuName.Text = Nothing Then
                supNo = Nothing
            Else
                supNo = "and a.ABAN8 like '%" & txtSuName.Text & "%'"
            End If
        End If

        If drp20.SelectedValue = Nothing Then
            cat20 = Nothing
        Else
            cat20 = " and b.drdl01ac20 = '" & drp20.SelectedValue & "'"
        End If

        If drp21.SelectedValue = Nothing Then
            cat21 = Nothing
        Else
            cat21 = "and c.drdl01ac21 = '" & drp21.SelectedValue & "'"
        End If

        If drp22.SelectedValue = Nothing Then
            cat22 = Nothing
        Else
            cat22 = "and d.drdl01ac22 = '" & drp22.SelectedValue & "'"
        End If

                sqlstr = "select distinct a.ABAN8 as Number, a.ABALPH as Name, a.ABAT1 as Type, g.aladdz as PostCode, " & _
        "b.drkyac20 as Level_1, b.drdl01ac20 as Level_1_Description,  " & _
        "c.drkyac21 as Level_2, c.drdl01ac21 as Level_2_Description,  " & _
        "d.drkyac22 as Level_3, d.drdl01ac22 as Level_3_Description,  " & _
        "g.aladd2 as Address, g.aladd3 as Address, g.aladd4 as Address, g.alcty1 as City, g.alcoun as County, g.alctr as Country " & _
        "FROM TRDTA.F0101 as a,  trdta.f0005_ac20 as b, trdta.f0005_ac21 as c, trdta.f0005_ac22 as d, trdta.f0005_ac23 as e, trdta.f0005_ac24 as f, trdta.f0116 as g  " & _
        "where ABAT1 IN ('V', 'VF', 'VM', 'VH') " & _
        "and trim(a.abac20) = trim(b.drkyac20) " & _
        "and trim(a.abac21) = trim(c.drkyac21) " & _
        "and trim(a.abac22) = trim(d.drkyac22) " & _
        "and a.aban8 = g.alan8 " & _
supNo & _
    supName & _
    cat20 & _
    cat21 & _
    cat22


        sqlconn.ConnectionString = connstr
        sqlconn.Open()
        sqlcmd.Connection = sqlconn

        sqlcmd.CommandText = sqlstr

        sqldr = sqlcmd.ExecuteReader


        GridView1.DataSource = sqldr
        GridView1.DataBind()
        sqldr.Close()
        sqlconn.Close()

This is the gridview as is currently stands...

 <asp:GridView ID="GridView1" runat="server" CellPadding="4" 
                EnableModelValidation="True" ForeColor="#333333" GridLines="None" 
                AllowPaging="false">

                 <Columns>
                    <asp:CommandField ShowSelectButton="True" />
                <%--    <asp:TemplateField>            
                    <ItemTemplate>                
                    <asp:CheckBox ID="chkSel" runat="server" />            
                    </ItemTemplate>        
                    </asp:TemplateField>--%>
                                       
                </Columns>

            <AlternatingRowStyle BackColor="White" />
            <EditRowStyle BackColor="#2461BF" />
            <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#507CD1" Font-Bold="False" ForeColor="White" Font-Size="12px" Font-Names="Arial" />
            <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
            <RowStyle BackColor="#EFF3FB" Font-Size="12px" Font-Names="Arial" />
            <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
        </asp:GridView>

Any and all help very much appreciated.

thanks
