I have a hierachal grid bound to a dataset. After modifying the dataset, The grid shows the following errors:

Warning 1 A column cannot be initialized unless it has a name. Parameter name: name Line 0 Column 0

Warning 2 A column cannot be initialized unless it has a name. Parameter name: name Line 0 Column 0

Please help.

Thanks.

This exception does not ring a bell.

Can you provide more details on what you are doing, and at which moment you do the DataSet update?  A bit of code snippet could help.
