Uno Mvux Feedview

FeedView Control — 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 FeedView Documentation

Search for and fetch the FeedView documentation:

uno_platform_docs_search("MVUX FeedView control displaying async data templates")

Primary documentation pages:

• FeedView Reference: external/uno.extensions/doc/Learn/Mvux/FeedView.md
• FeedView How-To: external/uno.extensions/doc/Learn/Mvux/Walkthrough/FeedView.howto.md

Fetch the full reference page:

uno_platform_docs_fetch(sourcePath="external/uno.extensions/doc/Learn/Mvux/FeedView.md")

Step 2: Understand FeedView Templates

From the fetched docs, extract the available templates:

• ValueTemplate (default <DataTemplate>) — shown when data is available
• ProgressTemplate — shown during loading
• ErrorTemplate — shown when an error occurs
• NoneTemplate — shown when there is no data

Step 3: For FeedView How-To Walkthroughs

For step-by-step implementation guidance:

uno_platform_docs_fetch(sourcePath="external/uno.extensions/doc/Learn/Mvux/Walkthrough/FeedView.howto.md")

This covers rendering IFeed<T>, IState<T>, customizing templates, and refresh behavior.

Step 4: For FeedView with Lists

If the user is displaying a collection feed, search for:

uno_platform_docs_search("MVUX FeedView list feed ListView collection display")

Key page:

• ListFeed How-To: external/uno.extensions/doc/Learn/Mvux/Walkthrough/ListFeed.howto.md

Key Principles (Stable)

• XAML namespace: xmlns:mvux="using:Uno.Extensions.Reactive.UI"
• Source property binds to the feed/state: Source="{Binding MyFeed}"
• Inside templates, access the data via {Binding Data} (e.g., {Binding Data.Name})
• The default <DataTemplate> content child acts as the ValueTemplate
• FeedView automatically provides a Refresh command — no need to create one manually
• FeedView handles all state transitions (loading → value → error) without code-behind
