On clicking DatePicker control return wrong date.

I have class:
class CmcDatePickerControl : public CXTPDatePickerControl


I am trapping message
void CmcDatePickerControl::OnLButtonDown(UINT nFlags, CPoint point)

Code is as follows:

CXTPDatePickerDaysCollection* pDaysCollection = NULL;

pDaysCollection = this->GetSelectedDays();

COleDateTime cDate;
struct CXTPDatePickerDaysCollection::SELECTED_BLOCK blk;

blk = pDaysCollection->GetSelectedBlock(0);
cDate.m_dt = (long)blk.nDateBegin;

 //DatetoStruct(, &ds);
 int nDay = cDate.GetDay();
 int nMonth = cDate.GetMonth();
int nYear = cDate.GetYear();

It's not returning me "Currently selected date" instead it's returning me "Previous selection date".

Same code works fine on:
void CmcDatePickerControl::OnLButtonDblClk(UINT nFlags, CPoint point)
returning correct date.

What am I doing wrong here?

Hi,
