No looks like this:

<asp:DropDownList ID="DropDownList2" runat="server">
            <asp:ListItem>1</asp:ListItem>
            <asp:ListItem>2</asp:ListItem>
            <asp:ListItem>3</asp:ListItem>
            <asp:ListItem>4</asp:ListItem>
            <asp:ListItem>5</asp:ListItem>
            <asp:ListItem>6</asp:ListItem>
            <asp:ListItem>7</asp:ListItem>
        </asp:DropDownList>

That's really strange if it is not working, I have tried your code:

-- front-code --
<asp:DropDownList ID="DropDownList2" runat="server">
            <asp:ListItem>1</asp:ListItem>
            <asp:ListItem>2</asp:ListItem>
            <asp:ListItem>3</asp:ListItem>
            <asp:ListItem>4</asp:ListItem>
            <asp:ListItem>5</asp:ListItem>
            <asp:ListItem>6</asp:ListItem>
            <asp:ListItem>7</asp:ListItem>
        </asp:DropDownList>
        <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">LinkButton</asp:LinkButton>

-- code-behind --
protected void LinkButton1_Click(object sender, EventArgs e)
    {
        int packID = Convert.ToInt32(DropDownList2.SelectedValue);
    }

This is working, is there something else that is using this code?
