I have a tree. The tree contains two columns. the second columns is a numeric cell. When a numeric cell in the tree is updated, I need to update its parent numeric cell with that number. I over ride OnGridCellInputComplete for this, but I don’t know how to get the TREEITEM of that cell, so I cannot call ItemGetParent to reach its parent. Any advise? Ron.

The CExtTreeGridWnd::ItemGetByVisibleRowIndex() converts a plain zero-based row index into a HTREEITEM handle. The CExtTreeGridWnd::ItemGetVisibleIndexOf() method converts a HTREEITEM handle into a plain zero-based row index. Please note it is not possible to get a plain row index of a tree item if at least one of its parent items is collapsed.
