Dear Support,

I get assent in the tree control in this place:




void CExtTreeGridCellNode::TreeNodeHiddenSet(
    CExtTreeGridDataProvider & _DP,
    bool bHide
    )
{
    ASSERT_VALID( this );
    ASSERT_VALID( (&_DP) );
    ASSERT_KINDOF( CExtTreeGridDataProvider, (&_DP) );
bool bHidden = TreeNodeHiddenGet();
    if( ( bHidden && bHide ) || ( (!bHidden) && (!bHide) ) )
        return;
    if( bHide )
    {
        if( TreeNodeIsDisplayed() )
        {
            ULONG nOffset = TreeNodeCalcOffset( true, false );
            if( nOffset != ULONG(-1L) )
            {
                ASSERT( _DP.m_arrGridVis[ nOffset ] == this ); <=== HERE


Sometimes I get this assert, and sometimes not.

Can you please explain why this happens? If I ignore the assert, the whole structure of the tree is messed up...

Thanks,

Ron.

We need a test project or at least a test function which generates this assertion.
