Hi,
I noticed a strange problem with ASP ListBox when RadFormDecorator is included in page. The multiple selection mode for ASP ListBox works fine when there is no RadFormDecorator in page. But when I included RadFormDecorator in page the ASP ListBox selection mode turns to Single mode though I have explicitly mentioned SelectionMode as Multiple. However, RadListBox works fine in both the cases.
This is with respect to RadControls 2009 Q3 version.

Please take a look at this issue and any solution would be very helpful to me.

The sample code and output snapshot are as follows:

    
            <%@ Page Language="VB" AutoEventWireup="false" CodeFile="DockTest.aspx.vb" Inherits="DockTest" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
