Hello,

I have a problem with the click around empty message in the RadListBox.

When i do click around empty message, the control throw an exception.

How i can disable the event selectedIndexChanged when there are not elements in
the RadListBox?

This is the error when i click on RadListBox (Empty):

Microsoft JScript runtime error: 'undefined' is null or not an object

The error is occurred at second line:

    
            this._activeItem=e; 
        
            d(e.get_element()).addClass("rlbActive"); 
        
            e.ensureVisible();

Code:

    
                                            <telerik:RadListBox ID="mailToSend" runat="server"  
        
                                                 EmptyMessage="Emailsssssss" Height="150px" Width="200px" 
        
                                                 SelectionMode="Multiple" AllowTransfer="True" TransferToID="mailToRemove"  
        
                                                 AutoPostBackOnTransfer="True" AllowReorder="True" AutoPostBackOnReorder="True" 
        
                                                 EnableDragAndDrop="True" Visible="false"> 
        
                                                 <EmptyMessageTemplate> 
        
                                                     Emailsssssss 
        
                                                 </EmptyMessageTemplate> 
        
                                             </telerik:RadListBox>
