Hi,
My application sets custom attributes from code-behind which works fine. The application also updates the value of appointment attributes in client-side code, e.g:
myClientSideAppointment.get_attributes().setAttribute("attributeName", someNewValue);
This is all fine until I move or resize an appointment with the mouse. It appears that the appointment attributes then revert to their originally-bound values, because when I subsequently click on an appointment after dragging or resizing it, the old attribute values are rendered by my click-handler code. Has anybody else seen this? (I'm using Internet Explorer 8 and the ASP.NET Ajax controls version 2010.2.929.35)
