Can't delete any rows from repeater

ASP.NET

I have made a repeater for my site in ASP.NET and tried adding a button which should delete a row from the repeater, but clicking the button doesn't do anything besides refreshing the page.

Repeater markup

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        <div class="detail">
Namn: <asp:Label ID="Label1" runat="server" Text='<%#Eval("Namn") %>'>'></asp:Label><br />
Address <asp:Label ID="Label3" runat="server" Text='<%#Eval("Adress") %>'></asp:Label><br />
Telefonnummer <asp:Label ID="Label4" runat="server" Text='<%#Eval("Telefonnummer") %>'></asp:Label><br />
Mailaddres <asp:Label ID="Label5" runat="server" Text='<%#Eval("Epost-address") %>'></asp:Label><br />
Meddelande: <asp:Label ID="Label6" runat="server" Text='<%#Eval("Kommentar") %>'></asp:Label><br />

<asp:LinkButton ID="lnkDelete" runat="server" CommandArgument='<%#Eval("Id") %>' CommandName="Delete" onclientclick="return confirm('Are you sure you want to delete?')">Delete</asp:LinkButton>
        </div>
    </ItemTemplate>
</asp:Repeater>

        SqlCommand sqlcm = new SqlCommand(str, sqlcn);
        sqlcm.Parameters.AddWithValue("@Id", id);
        if (sqlcn.State == ConnectionState.Closed)
        {
            sqlcn.Open();

        SqlConnection con = new SqlConnection(@"data source=(LocalDB)\v11.0;attachdbfilename=|DataDirectory|\Database.mdf;integrated security=True;multipleactiveresultsets=True;application name=EntityFramework");
        string command = "Select * from [Table]";
        SqlCommand cmd = new SqlCommand(command, con);
        if (con.State == ConnectionState.Closed)
        {
            con.Open();
        }
        Repeater1.DataSource = cmd.ExecuteReader();
        Repeater1.DataBind();
    }
}

Any ideas?

I have tried different variations of the deleting code but none have worked.
