I use the LPARAM of report grid nodes to hold a pointer to data created with new which is the only pointer to this data.  I override

the function  CExtReportGridWnd::_ReportItemUnRegisterImpl

so that I may delete the data before the node is actually removed and returned to the pool.  It was always successful until I tried to clear the Report of all nodes using the following:

LONG nRowCount = m_wndGrid.RowCountGet();

if( nRowCount > 0L )

{

HTREEITEM hRootItem = m_wndGrid.ItemGetRoot();

ASSERT( hRootItem != NULL );

if( hRootItem != NULL )

m_wndGrid.ItemRemove( hRootItem, true, true );

}

I have found that  _ReportItemUnRegisterImpl is not called in this case which is disaterous.

Can you recommend an override that I may implement to GUARANTEE that I will catch when a report item is removed.

Thanks

Please override the CExtTreeGridWnd::OnTreeGridNodeRemoved() virtual method in a CExtReportGridWnd-derived class. The CExtTreeGridCellNode * pointer is really the CExtReportGridItem * pointer in the case of report grid.

Never mind.  Duh, the answer is OnTreeGridNodeRemoved.  I requested that function last year.
