In v19.2.1, the following classes have become abstract:
- DxDataGridBase
- DxDataGridColumnBase
- DxDataGridComboBoxColumnBase
- DxDataGridCommandColumnBase
- DxDataGridDateEditColumnBase
- DxDataGridSelectionColumnBase
- DxDataGridSpinEditColumnBase
These classes serve as base classes for Data Grid columns and are not intended to be used explicitly. These changes will affect your application only if you created instances of these classes in C# code. In this case, update your code to use the corresponding descendants.
