How do I insert a row into a filtered tree grid whilst honouring if/where the new row should be inserted, other than to: 1. Save filters 2. Clear filters 3. Insert item 4. restore filters

It crashes calling ItemInsert(ItemGetRoot(), nIndex) when nIndex is greater than the number of visible rows, so I assumed nIndex was a visible index. Any sugestions?

Could you show the call stack listing at the assertion time?

Thanks for that. I manage my own sorting and want to insert an item between rows that may be hidden, can I do this without saving/clearing/restoring the filter? I would be nice if ItemInsert() could take a HTREEITEM instead of a visible row index & insert into the full grid whilst filters are applied - the new item only being displayed if it meets the filters criteria.

The CExtTreeGridWnd::ItemInsert() method does what you need. The nIdxInsertBefore parameter is an index in the array of all child nodes including the hidden ones. The CExtTreeGridWnd::ItemGetSiblingIndexOf() method allows you to convert a tree item handle into its sibling index.

You should insert a new row and initialize grid cells first. You don’t need to save/restore filters. The CExtGridWnd::OnGridFilterUpdateForColumns() / CExtGridWnd::OnGridFilterUpdateForRows() methods should be invoked to re-filter the grid control. The grid control uses these methods to re-filter edited data when the in-place grid cell editing is complete (CExtGridWnd::OnGridCellInputComplete()).
