Hello, RadGrid that has a master and detail tables and is rebinded to another data-source. Please automatically change all information and details of the RadGrid, including details-view. Currently, only the master table is rebinded, not the details. Please see an example of the problem in the my forum question: http://www.telerik.com/forums/radgrid-detailtable-doesn-t-rebind! Thanks, Daniel. .NET Programmer at ISR Corp
