Hi,

In new release load on demand stop working at all.

My sample:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="InfragisticsTests._Default" %>

    Namespace="Infragistics.Web.UI.NavigationControls" TagPrefix="ig" %>

The same configuration works fine in previous SR.

It is a little funny that the main functioanlity of data tree is corrupted.

    Hi

     

    Exactly the same issue with:

    Infragistics35.Web.v11.2, Version=11.2.20112.1019

     

    The same setup, the same scenario, the same exception.
