Problem
BOOL CGridSampleDoc::CanCloseFrame(CFrameWnd* pFrame)
{//Ensure that views can be deactivated
CView* pView = pFrame->GetActiveView();
if (pView &&pView->SendMessage(WM_GX_CANACTIVATE, 0, 0))
return FALSE;
// Is it a grid?
CGXGridCore* pGrid = NULL;
if(pView->IsKindOf(RUNTIME_CLASS(CGXGridView))) pGrid = (CGXGridCore*) ((CGXGridView*) pView);
elseif(pView->IsKindOf(RUNTIME_CLASS(CGXGridHandleView)))
pGrid = ((CGXGridHandleView*)pView)->GetGrid();
if (pGrid)
{
// Ensure that the current cell can be stored
if(!pGrid->TransferCurrentCell(TRUE, GX_UPDATENOW, FALSE))
{
// grid state is invalid, don't
// close the frame
return FALSE;
}
}
// Now, I can close the view
return CDocument::CanCloseFrame(pFrame);
}
You should also transfer the current cell data to the grid before saving the document.
Example:
|
BOOL CDbfBrowserDoc::OnSaveDocument(LPCTSTR pszPathName) |
|||
|
// TRACE1(CDocument: OnSaveDocument(%s) , pszPathName); // Ensure that each views current cell is stored // Now, I can save the document |
|||
|
return FALSE; |
|||
|
SetModifiedFlag(FALSE); return TRUE; |

|
} |
