I think you want linkbutton inside the repeater and not table. ???

See the Solution Posted by Me.

XML
(1) add itemcommand event to repeater
-----------------------------------------------------
<asp:Repeater ID="Repeater1" OnItemCommand="Repeater1_ItemCommand" runat="server">

(2) use following template in repeate control
----------------------------------------------
<ItemTemplate>
<td>
    <asp:LinkButton ID="LinkButton1" runat="server" CommandArgument='<%# Eval("FileUploaded") %>'
           CommandName="download">Download</asp:LinkButton>
</td>
</ItemTemplate>

(3) use this event for repeater control in codebehind file
--------------------------------------------------------------
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "download")
    {
        string filename = e.CommandArgument.ToString();
        string path = MapPath("~/Docfiles/" + filename);
        byte[] bts = System.IO.File.ReadAllBytes(path);
        Response.Clear();
        Response.ClearHeaders();
        Response.AddHeader("Content-Type", "Application/octet-stream");
        Response.AddHeader("Content-Length", bts.Length.ToString());
        Response.AddHeader("Content-Disposition", "attachment; filename=" +
        filename);
        Response.BinaryWrite(bts);
        Response.Flush();
    }
}

THANKS A LOT =)

When I use this, it seems to read the filename as System.Byte[]. Might there be a reason why string filename = e.CommandArgument.ToString(); isn't reading the filename properly?
You can add up the link button in Repeater's ItemTemplate and can get it in Repeater_ItemCommand event.


for detailed solution .Have a look at following URL.

LinkButton inside Repeater Control.

Hope it will help. :)
