Does anyone know how to set the style for the CXTPControlComboBox so that it automatically sorts the contents a la a real combo box? I just spent over $700 on this library and have wasted over an hour trying to figure out what ought to be a simple fix.

Here fix:

class CControlSortedComboBoxList : public CXTPControlComboBoxList
{
DECLARE_XTP_COMMANDBAR(CControlSortedComboBoxList);
public:

virtual void CreateListBox()
{
CreateEx(WS_EX_STATICEDGE | WS_EX_TOOLWINDOW, _T("LISTBOX"), _T(""),
LBS_SORT | WS_POPUP | WS_VSCROLL | WS_BORDER | WS_CLIPCHILDREN, CRect(0, 0, 0, 0), 0, 0);
}

};

class CControlSortedComboBox: public CXTPControlComboBox
{
DECLARE_XTP_CONTROL(CControlSortedComboBox)
public:

CControlSortedComboBox()
{
  if (m_pCommandBar)
  {
   m_pCommandBar->InternalRelease();
  }

m_pCommandBar = new CControlSortedComboBoxList();
((CControlSortedComboBoxList*)m_pCommandBar)-> ;CreateListBox();
}
};

...

IMPLEMENT_XTP_CONTROL(CControlSortedComboBox, CXTPControlComboBox)
IMPLEMENT_XTP_COMMANDBAR(CControlSortedComboBoxList, CXTPControlComboBoxList)

...

Usage:

CControlSortedComboBox* pComboFind = new CControlSortedComboBox;

pComboFind->SetDropDownListStyle();
pComboFind->SetEditHint(_T("Click to find string"));

   pComboFind->AddString(_T("Line1"));
   pComboFind->AddString(_T("Line3"));
   pComboFind->AddString(_T("Line2"));

   pComboFind->SetWidth(150);
   pComboFind->SetCaption(_T("Find"));
   pComboFind->SetStyle(xtpComboLabel);

lpCreateControl->pControl = pComboFind;
return TRUE;

Thank you, Oleg...I was afraid that was the only way to do this. I ended up just adding the LBS_SORT style to the CXTPControlComobBox class in the CreateListBox function and rebuilding. I almost never use a combo box without auto sorting, so it's easier just to do it this way and if I have to derive a new class without sorting, I'll just do it then. Why not a SetSortStyle member function in the future?

Added for next, release.

To prevent fixing your application for next release,

I recommend change it back and to add:

void ModifyListBoxStyle(DWORD dwRemove, DWORD dwAdd)

void CXTPControlComboBox::ModifyListBoxStyle(DWORD dwRemove, DWORD dwAdd)
{
if (IsValidList())
{
  CXTPControlComboBoxList* pComboBoxList = ((CXTPControlComboBoxList*)m_pCommandBar);

  pComboBoxList->m_dwStyle |= dwAdd;
  pComboBoxList->m_dwStyle &= ~dwRemove;

pComboBoxList->DestroyWindow();
pComboBoxList->CreateListBox();
}
}

And to fix CreateListBox as

void CXTPControlComboBoxList::CreateListBox()
{
CreateEx(WS_EX_STATICEDGE | WS_EX_TOOLWINDOW, _T("LISTBOX"), _T(""),
WS_POPUP | WS_VSCROLL | WS_BORDER | WS_CLIPCHILDREN | m_dwStyle, CRect(0, 0, 0, 0), 0, 0);
}

Usage:

CXTPControlComboBox* pComboFind = (CXTPControlComboBox*)CXTPControlComboBox::CreateObject();
pComboFind->ModifyListBoxStyle(0, LBS_SORT);

pComboFind->SetDropDownListStyle();
pComboFind->SetEditHint(_T("Click to find string"));

   pComboFind->AddString(_T("Line1"));
   pComboFind->AddString(_T("Line3"));
   pComboFind->AddString(_T("Line2"));

Any idea when a version will be released that contains this sorting change?

Thanks, Craig
