Date values presented outside Gantt Chart Library and Project Management Library for WPF

If you use a ListView based Gantt Chart control from Gantt Chart Library for WPF or Project Management Library for WPF, and you need to present date and time information for task values outside of the GridViewColumn.CellTemplate definitions (such as within a custom Edit Task dialog window), then instead of using the DateTimeBox control (that is pre-customized for showing date and time values within a grid cell), you should use the DateTimePicker control: it is available within the DlhSoft.Windows.Controls namespace (DlhSoft.Data.Controls assembly).
