how to code classic asp.net to open multiple browser instances (pages)

Question

I am working with .Net 4.0, where a user can see records in a GridView. What Im after is this:

1. User has access to the Gridview on the main page.
2. He clicks on a linkbutton from the gridview that launchers another browser instance (page 2).
3. He clicks on yet another linkbutton from the gridview that launches another browser instance (page 3).
4. Now that there are 3 browser instances, he can minimize, resize, etc. to compare all the details from pages 2 and 3, for example.

Can that be done with v4.0, with as little javascript as possible?

Hi @Coreysan,

You can try the code below.

<asp:TemplateField>
     <ItemTemplate>
        <asp:LinkButton Text="view1" ID="lnkView1" runat="server" OnClientClick="multiopen1()" />
     </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField>
     <ItemTemplate>
        <asp:LinkButton Text="view2" ID="lnkView2" runat="server" OnClientClick="multiopen2()" />
     </ItemTemplate>
 </asp:TemplateField>

<script type="text/javascript">
    function multiopen1() {
        window.open('WebForm2.aspx', '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');
    }
    function multiopen2() {
        window.open('WebForm3.aspx', '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');
    }
</script>

Use the HyperLinkFiled instead of LinkButton and set its Target property as needed.
