i had a problem with the docking manager when i updated from the version 3.2.0.0 to the version 4.1.0.62. the form that i used the docking manager is giving an exception at runtime and design time and the design is halting disallowing me to make any changes to the form. the exception that is raised is:

"Index and length must refer to a location within the string.
Parameter name: length
Source : mscorlib
Stack Trace :

Hi Ahmedhse,

Sorry for the inconvenience caused.This exception will raise only when the Name property of docked controls is empty.So please ensure that the name property as well as DockLabel has been set for all the docked controls.

Please let me know if you need further assistance.

Regards,
Joy
