Datagrid and buttonColumn

[Jonathan]

Hi everyone,
i am having a problem with some parameters. I got a datagrid with several
columns. My first column is hidden and contains a unique ID for a member.
My last column is a buttonColumn. Here's my datagrid code:

<asp:DataGrid id="Members" DataKeyField="I D_Membre"
OnItemCommand=" Members_ItemCom mand"
OnItemDataBound ="Members_OnIte mDataBound" AutoGenerateCol umns="false"
runat="server">
<Columns>
<asp:BoundColum n ReadOnly="True" DataField="ID_M embre"
Visible="False"/>
<asp:ButtonColu mn CommandName="In fo" HeaderText="Inf o." Text="<img
src='./Image.gif'>">
</asp:ButtonColum n>
</Columns>
</asp:DataGrid>

Sub Members_OnItemD ataBound (sender As Object, e As DataGridItemEve ntArgs )
e.Item.Cells(2) .Attributes.Add ("onClick", "return !window.open
('MembersInfo.a spx?id='+<%MY ID HERE%>);")
End Sub
I want to pass a parameter (My member's id from the hidden column) to a
file that i open with Window.open. So i am asking myself if i can pass that
parameter since my datagrid is built dynamically and if i am going in the
right direction with this code (using itemDatabound event)

Any help, information, code is greatly appreciated!
Thanx in advance.
