Xceed Toolkit Plus for WPF V5.2 (build 5.2.26322.84340)Jun 22, 2026
Features
Added a ChatControl, a XAML-definable chat UI for showing a conversation between a user and an assistant. You get customizable bubbles, corner radius, timestamps, a typing indicator, and an input area, which is enough to stand up an in-app support thread or an assistant experience without inventing the layout from scratch.
Added a WrapPanel view for ListBox. Until now ListBox could only stack its items in a single row or a single column. The new vertical or horizontal WrapPanel view flows items across lines or columns based on the container size.
On the AvalonDock side, routed commands now fire correctly when a LayoutAutoHideWindowControl contains a LayoutAnchorable, and the docking manager now resizes its children properly when its window is resized.

Xceed Datagrid for WPF
Opening the print preview window when a printer is configured to use a different default page orientation will no longer trigger a NullReferenceException.
A NullReferenceException no longer occurs in HeaderFooterItem.PrepareContainer when the grid loads.
