I have checkboxlist in my webpage . I also set autopostback property to true.

When I select any item in the checkbox. The selectedindexchanged event is not getting fired.

Where I am going wrong.

XML

<asp:CheckBoxList
                    ID="chkdecisionlist" runat="server"
                    RepeatLayout="OrderedList" AutoPostBack="True"
                    OnSelectedIndexChanged="chkdecisionlist_SelectedIndexChanged">

                    <asp:ListItem>Preview Weekend or Preview Day </asp:ListItem>
                    <asp:ListItem>Newspaper/Magazine Ad </asp:ListItem>
                    <asp:ListItem>Social Networking </asp:ListItem>
                    <asp:ListItem>MBA/Higher Education Fair </asp:ListItem>
                    <asp:ListItem>Rankings</asp:ListItem>
                    <asp:ListItem>Other Media </asp:ListItem>
                </asp:CheckBoxList>

Thanks,

Use update panel like below :

XML

<asp:UpdatePanel ID="Up" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:CheckBoxList
                    ID="chkdecisionlist" runat="server"
                    RepeatLayout="OrderedList" AutoPostBack="True"
                    OnSelectedIndexChanged="chkdecisionlist_SelectedIndexChanged">

                    <asp:ListItem>Preview Weekend or Preview Day </asp:ListItem>
                    <asp:ListItem>Newspaper/Magazine Ad </asp:ListItem>
                    <asp:ListItem>Social Networking </asp:ListItem>
                    <asp:ListItem>MBA/Higher Education Fair </asp:ListItem>
                    <asp:ListItem>Rankings</asp:ListItem>
                    <asp:ListItem>Other Media </asp:ListItem>
                </asp:CheckBoxList>
