As long as I only have a date and use the following format, everything works:

m_startDateCtrl = new CXTPPropertyGridItemDate("Start Date",   m_StartingDateTime);

m_startDateCtrl->SetDateFormat("%d-%m-%Y");

But when I try to show the date in the format "06-Oct-2006" as follows:

m_startDateCtrl->SetDateFormat("%d-%b-%Y");

m_startDateCtrl->SetMask("00-LLL-0000", "__-___-____");

The date does indeed show correctly, but now when I change the date in the calendar, the change is ignored in the property cell. It just keeps the old value.

If I try to add a time to my date, such as with the following:

m_startDateCtrl->SetDateFormat("%d-%m-%Y %I:%M %p");

m_startDateCtrl->SetMask("00-00-0000 00:00 LL", "__-__-____ __:__ __");

the value displays properly initially, but if I make changes with the keyboard directly in the property cell (to change the time), the changes are not saved when I leave the cell, but rather revert to the old value.

My two questions are, 1) how can I display a month as an abbreviation (e.g. Oct.) and still be able to edit the field; and 2) how can I display and edit the time along with the date?
