Use SetIconID - or look at CXTPControlPopupColor if you want to draw into the icon manually.

I want to display a bitmap which is not icon or button in toolbar. So "SetIconID" is not useful.

Perhaps you need to do a little more research of the documentation or header files. SetIconID is still probably what you want to use.
Just add your bitmap or icon to the image manager.

As variant you can draw control manually:

class CControlStatic : public CXTPControl
{
 DECLARE_XTP_CONTROL(CControlStatic)
protected:
 virtual CSize GetSize(CDC* pDC);
 virtual void Draw(CDC* pDC);
};

IMPLEMENT_XTP_CONTROL(CControlStatic, CXTPControl)

CSize CControlStatic::GetSize(CDC* pDC)
{
 BOOL bVert = GetParent()->GetPosition() == xtpBarRight || GetParent()->GetPosition() == xtpBarLeft;

 if (bVert) return CSize(30, 20);

 return CSize(20, 30);

}
void CControlStatic::Draw(CDC* pDC)
{

...
}

int CMainFrame::OnCreateControl(LPCREATECONTROLSTRUCT lpCreateControl)
 if (lpCreateControl->nID == ID_BUTTON_BITMAP3)
 {
  m_pControlBitmap = new CControStatic();
  
  lpCreateControl->pControl = m_pControlBitmap;
  return TRUE;
 }

and in "Draw()" of "CControStatic", I load a bitmap, but when I change the ID of bitmap, the bitmap in toolbar can not be changed at all. Could you tell me why?

Thanks.

CControlBitmap::CControlBitmap()
{
 m_nMyBitmapId = ID_BUTTON_BITMAP1;
  if (m_bmpControl1.GetSafeHandle())
   return;

  VERIFY(m_bmpControl1.LoadBitmap(ID_BUTTON_BITMAP ));
  if (m_bmpControl2.GetSafeHandle())
   return;

  VERIFY(m_bmpControl2.LoadBitmap(ID_BUTTON_BITMAP 1));
}
void CControlBitmap::SetBitmapId(int nBitmapId)
{
 m_nMyBitmapId = nBitmapId;
 }
void CControlBitmap::Draw(CDC* pDC)
{
  switch(m_nMyBitmapId)
 {
 case ID_BUTTON_BITMAP:
   pDC->DrawState(m_rcControl.TopLeft(), m_rcControl.Size(), &m_bmpControl1, DST_BITMAP);
  break;

 case ID_BUTTON_BITMAP1:
  pDC->DrawState(m_rcControl.TopLeft(), m_rcControl.Size(), &m_bmpControl2, DST_BITMAP);
  break;
 }
}

I debugged it, in "Draw(CDC* pDC)" m_nMyBitmapId is always ID_BUTTON_BITMAP1. I dont know why.
