Siegfried Pammer	065c9098fb	Cover tree mutation under a scrolled, virtualized SharpTreeView Issue #3290 reports a NullReferenceException inside SharpTreeNode.GetNodeByVisibleIndex, reached from a WPF virtualizing panel's measure pass. The frame is still live: the Avalonia SharpTreeView binds the TreeFlattener straight to ItemsSource, so Avalonia's virtualization indexes the same flat-list walk on every measure. Driving the model directly shows the indexer cannot walk off the end on one thread: TreeFlattener.Count and GetNodeByVisibleIndex read the same totalListLength fields with nothing in between, so a stale index becomes an ArgumentOutOfRangeException and never a null dereference. Randomized sweeps over insert/remove/expand/collapse/hide/reparent found no state where the two disagree. Only a mutation concurrent with the descent reproduces the reported frame, and every tree mutation in the app is marshalled to the UI thread. These tests pin the interleaving that the port changed: the flattened list shrinking underneath a realized index range, and a lazy subtree loading and reloading while scrolled. The first asserts the panel is actually virtualizing, so it cannot quietly degrade into a non-virtualized run that proves nothing. Assisted-by: Claude:claude-opus-5:Claude Code	2 weeks ago
Siegfried Pammer	51aafa0fd9	Move ILSpy UI code back to the ICSharpCode.ILSpy root namespace The Avalonia port had placed the UI app in an ILSpy.* namespace tree, while the csproj RootNamespace and every prior release (through 10.1) use ICSharpCode.ILSpy.*. Restoring the historical namespace reduces the public API diff against release/10.1 for plugin authors and removes the shadowing that forced global:: qualifiers in the test project. The Images class and AccessOverlayIcon enum move back into the root namespace (as in 10.1), since an ICSharpCode.ILSpy.Images namespace would shadow the Images class for all code inside ICSharpCode.ILSpy.

Siegfried Pammer	3e8e08644b	Add type-ahead search; prove native shift-range extend/shrink OnTextInput drives incremental prefix search over the visible (flattened) nodes with a 1s idle reset -- a fresh keystroke advances past the current row, a growing prefix refines forward. A regression test confirms the payoff of the ListBox base: SelectionMode.Multiple extends AND shrinks a shift-range from the anchor (Shift+Down x2 then Shift+Up -> A,B), so the migrated control needs none of the ProDataGrid reflection workaround.	3 months ago
Siegfried Pammer	85cf2bb61f	Scaffold a ListBox-based SharpTreeView control (Phase 1) First increment of the from-scratch Avalonia tree control that will replace the ProDataGrid hierarchical usage. SharpTreeView : ListBox binds the cross-platform TreeFlattener (an IList + INotifyCollectionChanged of visible SharpTreeNodes) straight as ItemsSource, so the ListBox virtualizes it and provides anchor-based extend/shrink selection natively -- no HierarchicalNode wrapper, no model<->grid sync layer. Includes Root/ShowRoot/ShowLines props, Reload/flattener wiring, deselect-on-hide, selection->node.IsSelected, FocusNode/ScrollIntoNodeView/HandleExpanding, container overrides, and the tree keyboard gestures (Left/Right, numpad +/-/*, Enter/Space activate). SharpTreeViewItem : ListBoxItem (double-click expand), an IPlatformRoutedEventArgs adapter, an indent converter, and a ControlTheme (chevron expander + indent + icon + text) wired into App.axaml. The control is additive and not yet wired to any pane. Smoke tests prove the core: flatten, virtualize, expand/collapse row-count updates, and selection sync.	3 months ago
