Hi bhushan98,

According to your description and needs, please check the following sample code:

<asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" AutoGenerateSelectButton="true">
                <Columns>
                    <asp:BoundField ItemStyle-Width="150px" DataField="CustomerID" HeaderText="Customer ID" />
                    <asp:BoundField ItemStyle-Width="150px" DataField="ContactName" HeaderText="Contact Name" />
                    <asp:BoundField ItemStyle-Width="150px" DataField="City" HeaderText="City" />
                    <asp:BoundField ItemStyle-Width="150px" DataField="Country" HeaderText="Country" />
                </Columns>
            </asp:GridView><br/>
            <asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="false" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" AutoGenerateSelectButton="true">
                <Columns>
                    <asp:BoundField ItemStyle-Width="150px" DataField="CustomerID" HeaderText="Customer ID" />
                    <asp:BoundField ItemStyle-Width="150px" DataField="ContactName" HeaderText="Contact Name" />
                    <asp:BoundField ItemStyle-Width="150px" DataField="City" HeaderText="City" />
                    <asp:BoundField ItemStyle-Width="150px" DataField="Country" HeaderText="Country" />
                </Columns>
            </asp:GridView>


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim tblDatas As DataTable = New DataTable
        tblDatas.Columns.Add("CustomerID", GetType(System.String))
        tblDatas.Columns.Add("ContactName", GetType(System.String))
        tblDatas.Columns.Add("City", GetType(System.String))
        tblDatas.Columns.Add("Country", GetType(System.String))
        tblDatas.Rows.Add("1", "2", "3", "4")
        tblDatas.Rows.Add("1", "2", "3", "4")
        tblDatas.Rows.Add("1", "2", "3", "4")
        tblDatas.Rows.Add("1", "2", "3", "4")
        GridView1.DataSource = tblDatas
        GridView1.DataBind()
        Dim dt As DataTable = New DataTable
        dt.Columns.Add("CustomerID", GetType(System.String))
        dt.Columns.Add("ContactName", GetType(System.String))
        dt.Columns.Add("City", GetType(System.String))
        dt.Columns.Add("Country", GetType(System.String))
        dt.Rows.Add("1", "2", "3", "4")
        dt.Rows.Add("1", "2", "3", "4")
        dt.Rows.Add("1", "2", "3", "4")
        dt.Rows.Add("1", "2", "3", "4")
        GridView2.DataSource = dt
        GridView2.DataBind()
    End Sub

    Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs)
        Dim gv As GridView = CType(sender, GridView)
        Dim Id As String = gv.ID
    End Sub
