Dear Support, I would like to repeat this from a previous thread, which I never got an answer to: Can you please add for the coming version passing of the parameters of grid, row & cell to the OnValueIncrement() and OnValueDecrement() methods? If you say they are invoked from the the CExtGridCell::OnButtonPressing() method, which does contain this information it does not seems to be too complicated. This is what I intend to do myself... If you want I can check it out and let you know if it works. Ron.

I would like to show you another problem in this issue - when an increment button is pressed, the grid is receiving an OnGridCellInputComplete call, but the cell does not! You can see it in CExtGridCell::OnButtonPressing:
... switch( nButtonType )
{
case __EBTT_UPDOWN_UP:
if( IsButtonEnabled(__EBTT_UPDOWN_UP)
&& OnQueryEnabledIncrement()
)
{
if( OnValueIncrement() )
{
wndGrid.OnGridCellInputComplete(
*this,
nColNo,
nRowNo,
nColType,
nRowType
);
bRedrawCell = true;
}
}
break;
case __EBTT_UPDOWN_DOWN:
if( IsButtonEnabled(__EBTT_UPDOWN_DOWN)
&& OnQueryEnabledDecrement()
)
{
if( OnValueDecrement() )
{
wndGrid.OnGridCellInputComplete(
*this,
nColNo,
nRowNo,
nColType,
nRowType
);
bRedrawCell = true;
}
}
break;
...
I think that the cell should be notified here that the cell was changed. I am going to do it myself, but I think that this is a fix that should be added to the library.

We modified the grid code. Here are the details: modified in CExtGridCell:
virtual bool OnQueryEnabledIncrement(
const CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
) const;
virtual bool OnQueryEnabledDecrement(
const CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
) const;
virtual bool OnValueIncrement(
CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
);
virtual bool OnValueDecrement(
CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
);
virtual bool OnQueryButtonInfo(
INT nButtonType,
CExtGridWnd * pWndGrid = NULL,
LONG nColNo = 0,
LONG nRowNo = 0,
INT nColType = 0,
INT nRowType = 0,
bool * p_bEnabled,
bool * p_bPressed = NULL,
bool * p_bStayPressed = NULL,
UINT * p_nTimerElapseValue = NULL
) const;
bool IsButtonEnabled(
INT nButtonType, // e_button_type_t
CExtGridWnd * pWndGrid = NULL,
LONG nColNo = 0,
LONG nRowNo = 0,
INT nColType = 0,
INT nRowType = 0,
) const;
bool IsButtonPressed(
INT nButtonType, // e_button_type_t
CExtGridWnd * pWndGrid = NULL,
LONG nColNo = 0,
LONG nRowNo = 0,
INT nColType = 0,
INT nRowType = 0,
) const;
bool IsButtonStayPressed(
INT nButtonType, // e_button_type_t
CExtGridWnd * pWndGrid = NULL,
LONG nColNo = 0,
LONG nRowNo = 0,
INT nColType = 0,
INT nRowType = 0
) const;
modified in CExtGridCellVariant:
virtual bool OnValueIncrement(
LPVARIANT pvarValue,
CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
);
virtual bool OnValueDecrement(
LPVARIANT pvarValue,
CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
);
modified in CExtGridCellComboBox::
void _DoItemsIterate(
CExtGridWnd & wndGrid,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType,
HWND hWndInplaceControl,
bool bNext,
bool bSetSel = false
);
added into CExtGridWnd:
virtual bool OnGridHookCellQueryEnabledIncrement(
LONG nColNo,
LONG nRowNo,
LONG nColType,
LONG nRowType,
const CExtGridCell & _cell,
bool & bEnabled
) const;
virtual bool OnGridHookCellQueryEnabledDecrement(
LONG nColNo,
LONG nRowNo,
LONG nColType,
LONG nRowType,
const CExtGridCell & _cell,
bool & bEnabled
) const;
virtual bool OnGridHookCellValueIncrement(
LONG nColNo,
LONG nRowNo,
LONG nColType,
LONG nRowType,
CExtGridCell & _cell,
bool & bResult
);
virtual bool OnGridHookCellValueDecrement(
LONG nColNo,
LONG nRowNo,
LONG nColType,
LONG nRowType,
const CExtGridCell & _cell,
bool & bResult
);
virtual bool OnGridHookCellQueryButtonInfo(
INT nButtonType,
const CExtGridCell & _cell,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType,
bool * p_bEnabled,
bool * p_bPressed,
bool * p_bStayPressed,
UINT * p_nTimerElapseValue,
bool & bRetVal
) const;
