Read-Only Behaviors NOT WORKING when Binding to Custom Collection
posted

I can't get built in behaviors to work when binding to my custom collection, it works perfectly when using a SQLDataSource. Is there something my custom collection needs to implement to get this functionality working correctly?? I've tried Dictionary, BindingList, and List, none of which have worked... Code is below:

 

ASPX

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication4.WebForm1" %>

 

<%@ Register Assembly="Infragistics4.Web.v10.2, Version=10.2.20102.1011, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"

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