    Redraw the grid so that the below grid becomes visible.

    Hi,

    I have created a single column and multiple rows Grid and had set an observer for it using SetListBoxObserver(this). I have handled the event in HandleListBoxEventL(), also created the scrollbarframe and its visibility is set CEikScrollBarFrame::EAuto. Now on the emulator screen only 5 items are being shown whereas I have got 12 items in GridModel. How to redraw the grid so that the below grid becomes visible after pressing the down-arrow on the last item on emulator screen?

    Re: Redraw the grid so that the below grid becomes visible.

    You should just pass the key events to the grid through the offerkeyevent function and the grid would take care of it by itself.

    Code:
    TKeyResponse MyContainer::OfferKeyEventL(const TKeyEvent& aKeyEvent, TEventCode aType)
        {
        return iGrid->OfferKeyEventL( aKeyEvent, aType );
        }
    To get the key events make sure to add the view to the control stack doing something like :-

    Code:
    void CAddressBookAppUi::ConstructL()
        {
        BaseConstructL();
        iCurrentView = CMyAppMainView::NewL( ClientRect() );
        AddToStackL( iCurrentView );
        }
    Cheers,
    Mayank

    Hi there,

    Thanks for the early reply.
    My Appui inherits from CAknViewAppUi so I have used AddViewL(View).
    And the rest is all done but it does't work.

    Are you calling SetContainerWindowL on grid control while constructing it?

    Hi,

    Yes I have set the container window for the grid control.
    The gridflag I have used is EAknListBoxSelectionGrid.

    Ok.

    I hope you are setting the layout, primary scrolling n secondary scrolling types properly.

    Check functions SetLayoutL SetPrimaryScrollingType SetSecondaryScrollingType.

    In SDK or wiki you will find example, pdf for grid too.

    Hope it helps.

    Re: Redraw the grid so that the below grid becomes visible.

    Hi,

    All those are fine.....
    But the scrollbar is not getting updated with the items or in other words I need to redraw the grid so that the below grid becomes visible after pressing the down-arrow on the last item on emulator screen.How to do that?
    OfferKeyEventL() is also done properly.
