I'm having a problem with the bindback behavior in mmGrid. There are time when I have an editable field that requires numeric or timestamp data, but is null-allowed. But because of the mmGrid.BindBack() method, I get an "System.FormatException" error when the bindback attempts to put an empty textbox value (empty string "") into a timestamp or numeric field in the dataset.

It appears I need to be able to override mmDataGrid.BindBack() so that I can change empty strings to DBNull, but this BindBack() is not an overridable method in mmDataGrid. Shouldn't it be (like mmTextBox, mmCheckBox, etc.)?

If so, will this change be in a release coming soon? Are there any suggestions that would help me handle this in the meantime?
