Urgent... Datagrid problem

Thanks in advance...I have what seems like it should be a simple thing
for a DataGrid. What I'll be using this for is for a user to choose an
employee record on the datagrid then hit the detail button or link and
launch a new window showing the details for that specific employee. So
my query string needs to pickup the employee's ID and take it to a
details window.Unfortunately I'm using 1.1 and the number of fields I
may need to display is about 40. So I may need to do a repeater
control on the detail form (?) so I can control all the html
positioning. Any clues on a 1.1 idea for that? Thanks!

Here's what I tried first, a datagrid with a LinkButton that I can't
get to work. My initial problem is the error:

BC30456: 'ViewDetails' is not a member of 'ASP.MainDepartment_aspx'.

Below is my html and my Code behind at the bottom:

<%@ Page Language="vb" AutoEventWireup="false"
Codebehind="MainDepartment.aspx.vb"
Inherits="Forsyth.HR_ReportingTool.UI.MainDepartment" %>
<FORM id="Form1" method="post" runat="server">
<asp:datagrid id="dgEmployees" >
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<asp:LinkButton ID="ViewDetails" CommandArgument='<%# Eval("id") %>'
Runat="server" OnCommand="ViewDetails">Details</asp:LinkButton>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid></FORM>
</BODY>
</HTML>

Protected Sub ViewDetails(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.CommandEventArgs)
Response.Redirect("Details.aspx?id=" & e.CommandArgument.ToString())
End Sub

________________________

I've also tried using the below <asp:hyperlink> technique... with
errors on the

<asp:TemplateColumn>
   <ItemTemplate>
<asp:HyperLink ID="ViewDetails" Runat="server" NavigateUrl='<%#
Eval("id","Details.aspx?id={0}") %>'>Details</asp:HyperLink>
   </ItemTemplate>
</asp:TemplateColumn>

Please try the following code

<asp:DataGrid ID="dgEmployees" Runat="server" AutoGenerateColumns="False">
                <Columns>
                    <asp:BoundColumn DataField="id" ReadOnly="True"
Visible="True"></asp:BoundColumn>
                    <asp:TemplateColumn>
                        <ItemTemplate>
                            <asp:LinkButton ID="ViewDetails" Runat="server"
CommandName="ViewDetails">Details</asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                </Columns>
            </asp:DataGrid>

private void dgEmployees_ItemCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
        {
            if(e.CommandName=="ViewDetails")
            {
                Response.Redirect("Details.aspx?id="+e.Item.Cells[0].Text);
            }
        }

Please Try this code.It will work
