Take your List Box into update panel, see below:

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
    <asp:UpdatePanel runat="server">
        <ContentTemplate>
            <asp:ListBox ID="ListBox1" SelectionMode="Multiple" OnSelectedIndexChanged="ListBox1_SelectedIndexChanged" AutoPostBack="true" runat="server">
                <asp:ListItem Text="text 1" Value="0"></asp:ListItem>
                <asp:ListItem Text="text 2" Value="1"></asp:ListItem>
                <asp:ListItem Text="text 3" Value="2"></asp:ListItem>
                <asp:ListItem Text="text 4" Value="3"></asp:ListItem>
                <asp:ListItem Text="text 5" Value="4"></asp:ListItem>
            </asp:ListBox>
        </ContentTemplate>
    </asp:UpdatePanel>
