- uno-mvux-feedview
- description
- Display async feed data with FeedView control.
- when_to_use
- Use when displaying data from an `IFeed<T>` or `IState<T>` in XAML, showing loading spinners, error messages, or empty-state UI automatically, customizing templates for different data states (value, progress, error, none), or binding feed data inside a `DataTemplate`.

# 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
