Hi,

I have a cell class derived from CExtPropertyValue in a CExtPropertyGridCtrl derived property grid.
I would like that all the options in the list will be checked when the user presses a button.
I have added a function with this as its content:
    
void CCheckComboProperty::SetCheckedItemData()
{
    CExtGridCellCheckListComboBox* pCell = (CExtGridCellCheckListComboBox*)ValueActiveGet();

    for (int k=0; k<pCell->GetCount(); k++)
    {
        pCell->ItemCheckSet(k, true);
    }
}

But nothing happens.

Please note that the grid calls PropertyStoreSynchronize() after this function, but still nothing.

Please let me know what i’m doing wrong, or fix this bug.

Thanks.

We are testing grid cell classes now. We would appreciate any additional comments and suggestions about particular grid cell classes.

Dear Support,
Am I true to assume that you were able to re-create the problem?

The CExtGridCellCheckListComboBox-related problem should not appear in the latest 2.62 you downloaded because the code that changes a list box item clears the empty state of the grid cell.

Any news?
Did you fix this bug?
Were you able to re-create it?

Dear Support,
The problem is in the latest version.
Please note that the problem have nothing to do with the new empty state (I think...) it has to do with the checked state as i described above.

I am attaching the original post :

It seems we found what the problem was caused by. Please find the CExtGridCellComboBox declaration and update these two ITEM_INFO constructors:

ITEM_INFO(
    __EXT_MFC_SAFE_LPCTSTR lpszString,
    DWORD dwItemData = 0,
    INT nImage = -1,
    INT nSelectedImage = -1,
    INT nOverlayImage = -1,
    INT nIndent = 0,
    INT nCheck = 0
    )
    : m_sString( lpszString )
    , m_dwItemData( dwItemData )
    , m_nImage( nImage )
    , m_nSelectedImage( nSelectedImage )
    , m_nOverlayImage( nOverlayImage )
    , m_nIndent( nIndent )
    , m_nCheck( nCheck )
{
}
ITEM_INFO( const ITEM_INFO & other )
    : m_sString( other.m_sString )
    , m_dwItemData( other.m_dwItemData )
    , m_nImage( other.m_nImage )
    , m_nSelectedImage( other.m_nSelectedImage )
    , m_nOverlayImage( other.m_nOverlayImage )
    , m_nIndent( other.m_nIndent )
    , m_nCheck( other.m_nCheck )
{
}

Dear Support,
Still waiting any reply regarding this bug.
Thanks,
Ron.
