Uno Toolkit Command Extensions

Uno Toolkit Command Extensions — Agent Skill

Workflow

Docs lookup: call uno_platform_docs_search(...) first, then uno_platform_docs_fetch(sourcePath="…") using the sourcePath field from a result (a relative .md path; add the result's anchor for a section). Never pass a URL, a .html link, or a hand-built path.

Step 1: Fetch the CommandExtensions Documentation

uno_platform_docs_search("Uno Toolkit CommandExtensions command TextBox enter ToggleSwitch ListView tap")

Primary documentation pages:

• CommandExtensions (Chefs): external/uno.chefs/doc/toolkit/CommandExtensions.md
• Command Extensions helper: search for CommandExtensions in toolkit helpers

Fetch the Chefs page:

uno_platform_docs_fetch(sourcePath="external/uno.chefs/doc/toolkit/CommandExtensions.md")

Step 2: For Reference Documentation

uno_platform_docs_search("Uno Toolkit CommandExtensions attached property Command CommandParameter")

Critical Rules

• There is no CommandTrigger attached property. utu:CommandExtensions.Command="{Binding ...}" alone is sufficient — the trigger event is determined automatically by the control type (Enter on TextBox/PasswordBox, item click on ListView, toggle on ToggleSwitch, invocation on NavigationView, tap on any UIElement). Do not invent a separate trigger property.
• Command on ListView requires IsItemClickEnabled="True" to fire.

Key Principles (Stable)

• utu:CommandExtensions.Command="{Binding MyCommand}" — attaches a command
• utu:CommandExtensions.CommandParameter — optional parameter
• Supported controls: TextBox (enter key), PasswordBox, ToggleSwitch, ListView, NavigationView, ItemsRepeater, any UIElement (tap)
• XAML namespace: xmlns:utu="using:Uno.Toolkit.UI"
