RepositoryItemCheckedComboBoxEdit goes empty on leaving cell

Question

I am creating an xtragrid in a windows form with one of the columns having a cell type RepositoryItemCheckedComboBoxEdit . I select multiple items and when i key out of the cell, the cell goes blank.

Please point me in the right direction and please explain what might be going on.

Answer 1

I realised that I hadn't assigned any field of the underlying datasource to the new column. Once I created the appropriate underlying field and assigned it to the new column, the individual cell would retain its value and no longer go blank.
