It seemed to me that the RadListBox control is no longer available in Telerik.Web.UI namespace in the latest version  2009.1.527.20 released on May 27, 2009. Did I miss anything? Does the RadComboBox take over the functionality? If yes, what should I do to achieve the similar functionality in RadListBox's AllowTransfer="true" TransferToID="targetcontrolid"?

Hello Tuan,

RadListBox is not included in the Q1 2009 release as it simply didn't existed then (version 2009.1.527.20 is actually Q1 2009). You have to upgrade to the latest release of RadControls for ASP.NET AJAX - Q2 2009 suite.

Kind regards,
Paul
