Is this a user control you created?
Please give me the specifics of what you are trying to do and how. The error
indicates an problem in the parent-child relationship in the control
hierarchy.

Failed to Load View State - GridView Dropdown error.

I am getting the same error.

I have Dropdownlist under GridView control bind to DataSource. First time i try to update the list will work fine but second time update is giving this error.

Any help will be appreciated.

Thanks
