What is devexpress-wpf-accordion?

A WPF user-interface control for building hierarchical navigation sidebars, where items can contain subitems. WPF is Microsoft’s framework for building Windows desktop applications.

Use it to add category menus, expandable application sidebars, navigation-pane tabs, glyphs, custom item content, and searchable navigation to a WPF app.

It removes the need to build tree navigation, search, expansion, and compact sidebar behavior from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00192	$0.04300
Opus 5	$0.00096	$0.02150
Sonnet 5	$0.00038	$0.00860
Haiku 4.5	$0.00019	$0.00430

Security

Grade A, and why

devexpress-wpf-accordion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DevExpress WPF Accordion Control

DevExpress.Xpf.Accordion.AccordionControl is a hierarchical navigation control with an unlimited tree depth, multiple selection / expand modes, optional Office-style navigation-pane layout, built-in search, and Office Navigation Bar integration. It's the recommended replacement for the older NavBarControl in new projects — simpler API, more customization room, modern look.

When to Use This Skill

Use this skill when you need to:

Add a hierarchical navigation sidebar to a WPF app
Define items statically in XAML, or bind to a ViewModel collection
Switch between Default (expand/collapse tree) and Navigation Pane (top-level items as tabs) view modes
Show items with glyphs, headers, custom content (editors, images)
Add a search field for end users to filter items
Collapse the panel into a compact strip with glyph-only items
Decide between AccordionControl, NavBarControl, and HamburgerMenu for navigation

Prerequisites & Installation

NuGet Packages

Package	Purpose
`DevExpress.Wpf.Accordion`	Main package — `AccordionControl`, `AccordionItem`
`DevExpress.Wpf.Navigation`	Required when integrating with `OfficeNavigationBar`

DevExpress.Wpf.Accordion transitively brings DevExpress.Wpf.Core.

.NET 8+

dotnet add package DevExpress.Wpf.Accordion

Add to .csproj:

<PropertyGroup>
  <TargetFramework>net8.0-windows</TargetFramework>
  <UseWPF>true</UseWPF>
</PropertyGroup>

All DevExpress packages in a project must share the same version.

Before You Start — Ask the Developer

If the host agent has a structured question-asking tool available, use it to ask these questions one at a time with clear options — for example, Claude Code's AskUserQuestion tool or GitHub Copilot's askQuestions tool. If no such tool is available, ask the questions directly in the chat response before generating code.

Target framework: .NET 8+ or .NET Framework 4.x?
Items source: static (defined in XAML) or dynamic (bound to a ViewModel collection)?
Data shape: all items the same type with a children property → ChildrenPath; mixed item types → ChildrenSelector; rich templating per level → HierarchicalDataTemplate. See data-binding.md.
View mode: Default (classic accordion) or NavigationPane (Outlook-style root tabs)?
Expand mode: how many items can be open at once — Multiple, MultipleOrNone, Single, SingleOrNone?
Search: should end users search the items? (ShowSearchControl)
Collapse: should the panel collapse into a compact strip? (IsCollapseButtonVisible)
Why Accordion vs alternatives: see when-to-use.md for the comparison with NavBarControl and HamburgerMenu.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
