How to catch ComboBox's messages

Hello,

A really silly question, but I don't know at all.
I have a combobox in command bars, created in CMainFrame::OnCreate like this,

    m_pComboYear = (CXTPControlComboBox*)m_pToolBar->GetControls()->Add(xtpControlComboBox,ID_YEAR);


I found ListBoxSample, but XTP_LBN_SELCHANGE is used for CXTPControlListBox.

How can I get notify when combo box changed selection?

Hi, HTH

Can I have more hint ablout HandleLocationCombo, FillLocationCombo.

CMainFrame::HandleLocationCombo(NMHDR* pNMHDR, LRESULT* pResult)
but How can I now this event is occured for which reason?

Thanks a lot.

For ON_NOTIFY, the CBN_* determines the event (drop down in this case, so I fill the list in FillLocationCombo).

ON_XTP_EXECUTE occurs when the selection is made (picked or typed).

You can get the control using:

CXTPControlComboBox *pcombo = (CXTPControlComboBox *)(((NMXTPCONTROL*)pnmh)->pControl)

Here is an example from my code:

afx_msg void CMainFrame::HandleLocationCombo(NMHDR* pnmh, LRESULT *pres)
{
    CXTPControlComboBox *pcombo = (CXTPControlComboBox *)(((NMXTPCONTROL*)pnmh)->pControl);
    if (pcombo) {
        ASSERT(pcombo->GetType() == xtpControlComboBox);
        CString foldername = pcombo->GetEditText();
        m_tree.PositionToFolder(foldername);
    }
}
