dear staff

it would be perfect to have a possibility to control the heigt of a combobox dropdown,
the hardcoded 12 lines is not really nice. m_dropdownitemcount would be much nicer!
best regards,
christoph braendle

BOOL CXTPControlComboBoxList::Popup(CXTPControlPopup* pControlPopup, BOOL /*bSelectFirst*/)
{
SetFont(CXTPPaintManager::GetIconFont());
m_pControlPopup = pControlPopup;
CWnd* pWndOwner = GetOwnerSite();
if (pWndOwner)
pWndOwner->SendMessage(WM_XTP_INITCOMMANDSPOPUP, , (LPARAM)this);
SetTrackingMode(TRUE, FALSE);
UpdateFlags();
CRect rcControl = pControlPopup->GetRect();
int nItemHeight = ((CListBox*)this)->GetItemHeight(0);
int nHeight = min ( 12 , max(1, ((CListBox*)this)->GetCount())) * nItemHeight + 4;
int nWidth = m_nMRUWidth <= 0? rcControl.Width(): m_nMRUWidth;
SetPosition(CSize(nWidth, nHeight));
return TRUE;
}

Please add the same method for the PropertyGrid's InPlaceList.

I've always been patching the XTP source code, that's not a good way to do it :)
