Hi,

i have a project that use all components from infragistics 2013 vol1 and this project creates winpanel and child controls in the clientarea of the panel dynamically/programmatically

It works like a charm since i added the "UltraTouchProvider", the code where i dispose the winpanel throws an "InvalidOperationException" :

The error message :

Operation is not valid due to the current state of the object.

The stacktrace :

   at Infragistics.Win.ChildControlEventManager..ctor(Control rootControl)

   at Infragistics.Win.ControlUIElementBase.Initialize(Control control, IUltraControl ultraControl, ProcessEvent eventsToProcess)
