[RESOLVED] Of CComboBox and CListCtrl on a CDialog

[Mustafa]

Hi all gurus,

Thought this was simple and straight forward but got stuck with the most trivial problem and in need of your help...

I have a ListCtrl on a dialog and all I am trying to do is paste a CComboBox object on the fly when user clicked on the List Control, I filled the CComboBox with values and when the user selects an item in the ComboBox it will update the column in the ListCtrl..

I inherit a new class from CComboBox and named it CComboBoxItem and overide the CComboBoxItem::OnSelchange().

On the click event of the ListCtrl, I had created the CComboBoxItem object on top of the column which the user clicked...all is fine, but when user selects an item in the CComboBoxItem, the OnSelchange was NOT triggered??..when I created it, I set the parent as the CListCtrl. But when I set the parent as the Dialog holding the CListCtrl, the OnSelchange event got triggered...

Any ideas why?? Here's a snippet of the codes

void CSettingDlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult) 
{
	// TODO: Add your control notification handler code here
	NMLISTVIEW & nm = *(NMLISTVIEW *) pNMHDR; //This converts the pNMHDR to the specific column and row

	if (nm.iItem==-1||nm.iSubItem==0)
	{
		if(m_pCombo)
		{
			m_pCombo->DestroyWindow();
			delete m_pCombo;
			this->m_pCombo=NULL;
		}
		return;//No need to go on user clicked on empty area or on column 1...no editing
	}

	CListCtrl* pList=(CListCtrl*)this->GetDlgItem(IDC_LIST1);
	CRect rect;
	pList->GetSubItemRect(nm.iItem,nm.iSubItem,LVIR_LABEL,rect);
	if(m_pCombo)
	{
		m_pCombo->DestroyWindow();
		delete m_pCombo;
		this->m_pCombo=NULL;
	}

	this->m_pCombo=new CComboBoxItem;
	int nHeight=rect.Height();//Just to save the height
	rect.bottom+=70;
	this->m_pCombo->Create(WS_VISIBLE|WS_CHILD|CBS_DROPDOWNLIST|WS_VSCROLL,rect,pList,NULL);

        //But if I did this, the CComboBoxItem::OnSelchange event got triggered??
        //this->m_pCombo->Create(WS_VISIBLE|WS_CHILD|CBS_DROPDOWNLIST|WS_VSCROLL,rect,this,NULL);


	this->m_pCombo->SetDroppedWidth(70);
	this->m_pCombo->SetFont(pList->GetFont());

//and so forth.....
}

//Here's another snippet from CComboBoxItem

BEGIN_MESSAGE_MAP(CComboBoxItem, CComboBox)
	//{{AFX_MSG_MAP(CComboBoxItem)
	ON_CONTROL_REFLECT(CBN_SELCHANGE, OnSelchange)
	ON_CONTROL_REFLECT(CBN_CLOSEUP, OnCloseup)
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

Help...pls
