Server Side Events not Firing
posted

All,

I'm trying to take a 2011 vol 1 UltraWebListBar and upgrade it to a 2013 Web Explorer Bar.  I was hoping to just take the code behind and modify slightly and all would be good.  The problem I am having is that none of the Server Side ItemClick events are firing.  There is a lot going on in the page in question so I just created a simple page with the one control, but still none of the server side events would fire.  I'm not sure what I am doing wrong here and any help would be great.

I've got some over simplified source below:

Aspx:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>

var itemValue = args.getExplorerBarItem().get_value();

}

    Hello Joe,

    In order to hit the breakpoints a postback or ajax call should be made to the ServerSide. AutoPostBackFlags tag should be used. I suggest you use one of the following AutoPostBackFlags Tag property’s settings, regarding your application requirements.

    ItemClick="On" /"Async”;
    ItemSelected="On"/"Async”;

    Modified Code From The Attachement:
    <ig:WebExplorerBar ID="uwlbMainMenu" runat="server" Width="250px">
    <AutoPostBackFlags ItemClick="On" ItemSelected="On"/>
    </ig:WebExplorerBar>


    Please let me know if you need further assistance regarding this issue!
