Dear Support, I am sending you another application to reproduce a bug related to ItemHide and ItemRemove. Please re-evaluate these two functions, as there are sevral issues there, and our code rely on these two functrion. Please let us know that you received the application that you were able to reproduce the bug. Thanks, Ron.

You can fix this by updating the following method:</p> 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 );
INT nCountToRemove = _ContentWeight_Get( true );
_DP.m_arrGridVis.RemoveAt( nOffset, nCountToRemove + 1 );
CExtTreeGridCellNode * pNodeParent = TreeNodeGetParent();
if( pNodeParent != NULL )
{
ASSERT_VALID( pNodeParent );
pNodeParent->_ContentWeight_Decrement( nCountToRemove + 1, true );
}
}
}
ModifyStyleEx( __EGCS_EX_HIDDEN_TREE_NODE, 0 );
} // if( bHide )
else
{
ModifyStyleEx( 0, __EGCS_EX_HIDDEN_TREE_NODE );
if( TreeNodeIsDisplayed() )
{
_ContentWeight_Adjust();
ULONG nOffset = TreeNodeCalcOffset( true, false );
if( nOffset != ULONG(-1L) )
{
m_nContentWeightAll = ULONG( m_arrChildren.GetSize() );
INT nCountToInsert = _ContentWeight_CalcVisible();
//INT nCountToInsert = _ContentWeight_Get( true );
// ULONG nOffset = TreeNodeCalcOffset( true );
// ASSERT( nWeightVisible >= pNode->TreeNodeGetChildCount() );
_DP.m_arrGridVis.InsertAt( nOffset, NULL, nCountToInsert + 1 );
_DP.m_arrGridVis.SetAt( nOffset, this );
nOffset ++;
_Content_FillVisibleArray( _DP.m_arrGridVis, nOffset );
// CExtTreeGridCellNode * pNodeParent = TreeNodeGetParent();
// if( pNodeParent != NULL )
// {
// ASSERT_VALID( pNodeParent );
// pNodeParent->_ContentWeight_Increment( nCountToInsert + 1, true );
// }
}
}
} // else from if( bHide )
}
This is not the final fix. We are working on a similar issue related to more complicated nested row layouts in report grid. The fix above is related to a tree grid only.
