Add itemtemplate columns value as querystring in popup window genereted by Linkbutton in gridview

Hello all,

Would appreciate if anyone could help me.

I have two columns in my gridview, 1st column is a templatefield for capturing rownumber of grid and 2nd column is a link button clicking on which i am opening a pop up window.

<columns>
    <asp:TemplateField HeaderText="RowNum" Visible="false"> 
    <itemtemplate> 
    <asp:Label ID="lblRowNum" runat="server" Text="<%#Container.
    DataItemIndex + 1>">
    </itemtemplate> 

    <asp:TemplateField HeaderText="FileName"> 
    <itemtemplate>
    <asp:LinkButton ID="btn"  runat="server" Text='<%#Eval("Empid")%>'
    CommandName="Click" OnClientClick='<%# Eval("FileName", "window.open
    (\"abc.aspx\",null,\"location=0,status=0,toolbar=0,
    menubar=0,resizable=1\",\"true\");")%>'/>
    </itemtemplate>

This works fine however i want to pass text of label(from first column) as querystring of popup window.

Could it be done in codebehind or within window.open of my javascript code which i am calling onclick event of link button.

Thanks in advance
