closes #13454

Summary by CodeRabbit

  • New Features
    • Progress indicators can inherit shared settings, including appearance, layout, and announcement options.
    • Customize progress colors, sizing, typography, corner radius, stripes, and animation timing with public CSS variables.
    • Delay the initial display of progress indicators, with support for keeping them hidden during prerendering.
    • Progress announcements use the accessibility label when available, otherwise the visible label.
  • Improvements
    • Circular progress indicators support custom diameters and size-aware readouts and thickness.
    • Progress labels wrap instead of being cut off, and malformed percentage formats fall back to the default.
    • Progress indicators provide improved accessibility semantics across linear and circular layouts.
  • Documentation
    • Expanded examples and guidance cover progress modes, readouts, buffering, styling, accessibility, cascading settings, and right-to-left layouts.

Walkthrough

BitProgress adds cascading configuration and delayed visibility. It updates progress accessibility attributes, value normalization, circular sizing, and configurable CSS properties. The demo and tests now cover these behaviors and settings.

Changes

BitProgress enhancements

Layer / File(s) Summary
Cascading progress parameters
src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgressParams.cs, src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.razor.cs, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Progress/ProgressBar/BitProgressParamsTests.cs, src/BlazorUI/Tests/Bit.BlazorUI.Tests.Mcp/ComponentCatalogTests.cs, src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Progress/Progress/*
BitProgressParams exposes nullable progress settings. BitProgress applies cascaded values unless markup sets the corresponding parameter, and restores replaced values when the cascade stops supplying them. Tests and demo examples cover cascading, precedence, and restoration.
Delay, accessibility, and value handling
src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.razor, src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.razor.cs, src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.scss, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Progress/ProgressBar/BitProgressTests.cs
BitProgress adds delayed visibility and prerender handling. Linear progress role and ARIA attributes move to the full-width container. NaN values normalize to zero, malformed percentage formats use the default, and announcements prefer AriaLabel over Label.
Public styling properties and circular rendering
src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.razor, src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.razor.cs, src/BlazorUI/Bit.BlazorUI/Components/Progress/Progress/BitProgress.scss, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Progress/ProgressBar/BitProgressStylesheetTests.cs, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Progress/ProgressBar/BitProgressTests.cs
The stylesheet reads public CSS properties for progress colors, sizing, typography, radius, stripes, and transitions. Circular diameter is applied through the root style. Circular stroke width uses the configurable thickness property and a fallback, with a 20% cap.
Progress examples and behavior coverage
src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Progress/Progress/*, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Progress/ProgressBar/*, src/BlazorUI/Tests/Bit.BlazorUI.Tests.Mcp/ComponentCatalogTests.cs
The demo examples and descriptions are reorganized to cover progress modes, readouts, dimensions, accessibility, styles, cascading parameters, and right-to-left content. Tests cover cascaded parameters, rendering, delay, announcements, value handling, and stylesheet contracts.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature

Merge Risk: ⚪ Minimal · up to b051e

BitProgress gains cascading defaults, delayed display, accessibility fixes, and public CSS variables, with broad test coverage. No actionable defect remains, so the change is ready to merge after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to b051e

The changes can affect progress components throughout an application, but the reviewed paths remain within UI rendering and show no new access to privileged services or data. Some security coverage remains incomplete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The shared progress component has a broad potential UI-consumer reach, but cascade application and restoration occur per component instance.

Trust Boundaries and Controls

  • inferred — Consumer-supplied labels, attributes, styles, and progress values reach the component’s rendering surface; the inspected change does not route them to a privileged service or security decision.

Resilience and Maintainability Implications

  • observed — The delay completion path checks for disposal or an inactive delay before requesting a render, and disposal cancels pending work.

A rabbit checks the progress ring,
Then hops where CSS colors spring.
A delayed bar waits out its time,
Cascaded settings fall in line.
The labels wrap; the values stay,
The rabbit bounds along its way.
A final carrot marks the day.

- Line 357: Update the cascade parameter handling used by BitProgress when
UpdateParameters(this) runs: when a cascade setting is cleared or the cascade
disappears, restore component defaults for values previously supplied by the
cascade, including rounded, range, and announcement settings. Track
cascade-supplied values so directly assigned parameters remain unchanged.
