Hello,

I’m using CExtGridWnd in my dialog.

I have to apply some logic after user has finished edit the cell.

Is there some way to get a notification message in my dialog box window procedure?

Or there is another way to handle this?

I’ll appreciate some example of sourcecode.

Thanks.

 

Hi,

Thanks for the prompt responce.

The first method works just fine for me.

 

You need to declare a CExGridWnd-derived class and override the CExtGridWnd::OnGridCellInputComplete() virtual method in it. It is called when in-place editing is complete and the cell value has been changed.

virtual void OnGridCellInputComplete(
  CExtGridCell & _cell,
  LONG nColNo,
  LONG nRowNo,
  INT nColType,
  INT nRowType,
  HWND hWndInputControl = NULL
  );

void CMyGridWnd::OnGridCellInputComplete(
 CExtGridCell & _cell,
 LONG nColNo,
 LONG nRowNo,
 INT nColType,
 INT nRowType,
 HWND hWndInputControl // = NULL
 )
{
 ASSERT_VALID( this );
 ASSERT_VALID( (&_cell) );
    .....
    .....
    .....
}

You can also use derived cell classes with the overridden CExtGridCell::OnInplaceControlTextInputComplete() virtual method, which is also called when in-place editing is complete.

 virtual void OnInplaceControlTextInputComplete(
  HWND hWndInplaceControl,
  CExtGridWnd & wndGrid,
  LONG nVisibleColNo,
  LONG nVisibleRowNo,
  LONG nColNo,
  LONG nRowNo,
  INT nColType,
  INT nRowType,
  __EXT_MFC_SAFE_LPCTSTR sTextNew,
  bool bSaveChanges
  );

 
void CExtGridCell::OnInplaceControlTextInputComplete(
 HWND hWndInplaceControl,
 CExtGridWnd & wndGrid,
 LONG nVisibleColNo,
 LONG nVisibleRowNo,
 LONG nColNo,
 LONG nRowNo,
 INT nColType,
 INT nRowType,
 __EXT_MFC_SAFE_LPCTSTR sTextNew,
 bool bSaveChanges
 )
{
 ASSERT_VALID( this );
 ASSERT( hWndInplaceControl != NULL && ::IsWindow(hWndInplaceControl) );
 ASSERT_VALID( (&wndGrid) );
 hWndInplaceControl;
 wndGrid;
 nVisibleColNo;
 nVisibleRowNo;
 nColNo;
 nRowNo;
 nColType;
 nRowType;
 sTextNew;
 if( bSaveChanges )
 {
  TextSet( sTextNew );
  CExtGridDataProvider & _DataProvider = wndGrid.OnGridQueryDataProvider();
  _DataProvider.SortOrderUpdate( true, &wndGrid );
  _DataProvider.SortOrderUpdate( false, &wndGrid );
  CPoint ptFocus = wndGrid.FocusGet();
  if( ptFocus.x >= 0 )
   wndGrid.EnsureVisibleColumn( ptFocus.x );
  if( ptFocus.y >= 0 )
   wndGrid.EnsureVisibleRow( ptFocus.y );
 }
 wndGrid.OnGridCellInplaceControlTextInputComplete(
  *this,
  hWndInplaceControl,
  nVisibleColNo,
  nVisibleRowNo,
  nColNo,
  nRowNo,
  nColType,
  nRowType,
  sTextNew,
  bSaveChanges
  );
 
if( bSaveChanges )
{
    .....
    .....
    .....
}

}
