When I have single item selected and focused, when I click to it’s expand button, you unset the focus and then set focus to the same item again. Why do you do that? It is causing unnecessary flashing in my other window which is showing some details for focused/selected item.

The CExtTreeGridWnd::ItemExpand() method performs these focused item manipulations. This is required to ensure the focused row in the CExtTreeGridWnd control is never under collapsed row. The focused row resetting is always performed without tree grid re-painting.

Can’t you check whether focus/selection really needs to be changed first? Tree is not redrawn, but my OnGbwSelectionChanged() is called twice, first with NULL focus, then with previous focus and my status window is flashing. It was not so bad in 2.87
