I have had many, MANY questions asking how to use my MFC grid control
in a view instead of in a dialog, so hopefully this will help.
The easiest way as I see it is as follows:
- Add a member variable of type CGridCtrl* to your view class:
- Initialise this to NULL in your view class’ constructor:
m_pGrid = NULL;
- In the CView function OnInitialUpdate, create a new CGridCtrl object if the m_pGrid
is not NULL, and then create the CGridCtrl window:
if (m_pGrid == NULL) // Have we already done this bit?
m_pGridCtrl = new CGridCtrl; // Create the Gridctrl object
if (!m_pGridCtrl) return;
CRect rect; // Create the Gridctrl window
m_pGridCtrl->Create(rect, this, 100);
m_pGridCtrl->SetRowCount(50); // fill it up with stuff
// … etc
This allows the view to be reused (eg SDI situations).
- We want the grid to take up the whole of the view’s client space, so add a handler to
the WM_SIZE message for the view and edit the OnSize function thus:
CMyView::OnSize(UINT nType, int cx, int cy)
CView::OnSize(nType, cx, cy);
if (m_pGrid->GetSafeHwnd()) // Have the grid object and window been created yet?
GetClientRect(rect); // Get the size of the view’s client area
m_pGrid->MoveWindow(rect); // Resize the grid to take up that space.
- Remember to delete the object when you are done:
- You may want to also add an OnCmdMsg
overide to your view class and let the grid control have first go at
the messages (this will allow commands such as ID_EDIT_COPY to be wired in
BOOL CMyView::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
if (m_pGrid && IsWindow(m_pGrid->m_hWnd))
if (m_pGrid->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
return CView::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
