            InitializeComponent();
            repositoryItemDateEdit1.BeforePopup += RepositoryItemDateEdit1_BeforePopup;
        }

        void RepositoryItemDateEdit1_BeforePopup(object sender, EventArgs e) {
            PopupDateEditForm popupForm = ((DateEdit)sender).GetPopupEditForm() as PopupDateEditForm;
            popupForm.Calendar.CalendarTimeEditing = DefaultBoolean.True;
        }
    }
}

VB.NET

Imports DevExpress.XtraEditors.Popup
Imports DevExpress.XtraEditors
Imports DevExpress.Utils
Imports System

Namespace DXApplication
    Public Partial Class Form1
        Inherits XtraForm

        Public Sub New()
            InitializeComponent()
            AddHandler repositoryItemDateEdit1.BeforePopup, AddressOf RepositoryItemDateEdit1_BeforePopup
        End Sub

        Private Sub RepositoryItemDateEdit1_BeforePopup(sender As Object, e As EventArgs)
            Dim popupForm As PopupDateEditForm = CType(CType(sender, DateEdit).GetPopupEditForm(), PopupDateEditForm)
            popupForm.Calendar.CalendarTimeEditing = DefaultBoolean.True
        End Sub
    End Class
End Namespace
