        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button Text="Details" ID="Inkview" runat="server" OnClick="Inkview_Click" ForeColor="white"  BackColor="#FF6600"/>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button Text="Delete" ID="lnkView1" runat="server" OnClick="Inkview_Click1"     ForeColor="white"  BackColor="#FF6600"/>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

protected void Inkview_Click(object sender, EventArgs e)
{
    int id = 0;
    int.TryParse(hfId.Value, out id);
    Session["DatakeyValue"] = id;
    Response.Redirect("rrrr.aspx");
}

$(document).on('click', '.view', function () {
    $('[id*=hfId]').val($(this).closest('tr').find('td').eq(1).html());
});
