Hi Javier,
I have consulted the development team regarding this issue, and will update you as soon as I hear from them. Meanwhile, please do the following checks :
1. Check the GAC to ensure that only v2.0.2.1 dlls are present.
2. Delete any Syncfusion policy files that may be present.
3. Remove all the Syncfusion dll references in the Property grid in the designer, and re-add them.
4. Now rebuild your application and let us know how it goes.
I have also attached a
sample_application here which is very similar to your application. Try this and let me know if you can recreate the problem. Thanks for your cooperation.
Regards,
Guru Patwal
