Why in the sample DatePickerDemo Dialog does not receive XTP_NC_DATEPICKER_BUTTON_CLICK messages when coming from Combo CDatePickerCombo class?
Is it a bug?

Thanks!

Hello jmarcosf,

Thank you for bringing this to our attention. There is really error in file

Samples\Calendar\DatePickerDemo\DatePickerDemoDlg.cpp line ~196

   ON_NOTIFY(XTP_NC_DATEPICKER_BUTTON_CLICK, 1000, OnButtonPressed)

File Resource.h has two the same IDs 1000

#define IDC_CUSTOM1                     1000#define IDC_DATEPICKER                  1000

So IDC_CUSTOM1 hides IDC_DATEPICKER and CDatePickerDemoDlg::OnButtonPressed doesn't get XTP_NC_DATEPICKER_BUTTON_CLICK notification.
Solution is removing IDC_CUSTOM1 from Resource.h and change ON_NOTIFY() declaration to

   ON_NOTIFY(XTP_NC_DATEPICKER_BUTTON_CLICK, IDC_DATEPICKER, OnButtonPressed)

I have fixed this in sample application.

Regards,

Oleksandr Lebed

Making that modifications doesn't really solve the problem.
It still continues without printing any TRACE as the blue buttons from the main DatePickerControl does.
Besides, IDC_DATEPICKER is the resource id of this main DatePickerControl but, on the fly generated controls when yo click popup controls do not have this ID. I think that is the real problem. According to the source, popup controls are always created with resource id 0.

By adding the next line, the messages from first popup control is showed but not the ones coming from the combo box.

ON_NOTIFY(XTP_NC_DATEPICKER_BUTTON_CLICK, 0, OnButtonPressed)
