Hello. When I push the cell button and execute RowRemoveAll of own.
Assert appears.
I am troubled.
Please teach measures method. http://ifreeta.dee.cc/20090518/SampleMuGrid200904.lzh 
bool CNxL_MlGrid::OnGridCellButtonPressed(
CExtGridCell & _cell,
INT nButtonType,
const RECT & rcCellExtra,
const RECT & rcCell,
LONG nVisibleColNo,
LONG nVisibleRowNo,
LONG nColNo,
LONG nRowNo,
INT nColType,
INT nRowType
)
{ RowRemoveAll(); return true;
}
