Summary

This PR implements a feature to organize Parameter resources in the Aspire Dashboard by grouping them under a collapsible "Parameters" parent row in the Resources table. This creates a cleaner UI that helps users focus on runtime components while still providing easy access to configuration parameters.

Changes Made

Parameters Grouping

  • Created a synthetic "Parameters" parent resource that groups all parameter resources
  • All Parameter resources are set as children of this "Parameters" parent
  • The Parameters group is auto-collapsed by default to reduce visual clutter
  • Users can expand the Parameters row to view individual parameter resources

Implementation Details

  • Modified GetData() method to inject synthetic Parameters parent resource
  • Added GroupParametersUnderParent() helper method that:
    • Detects Parameter resources
    • Creates a synthetic "Parameters" parent resource
    • Updates each parameter to have "Parameters" as its parent (via ParentName property)
    • Adds the Parameters group to the collapsed resources list by default
  • Leverages existing parent-child resource infrastructure (no UI changes needed)

Testing

  • All 82 Dashboard Component tests pass ✅
  • All Dashboard tests pass ✅
  • Existing collapse/expand functionality works with Parameters group

Benefits

  • Cleaner UI: Parameters are grouped and collapsed by default, reducing visual clutter
  • Better Organization: All parameters grouped under one expandable row
  • Reduced Cognitive Load: Users focus on runtime components, can expand Parameters when needed
  • Improved UX: Simple, familiar collapse/expand pattern
  • No Breaking Changes: Reuses existing parent-child resource infrastructure
  • Minimal Code Changes: Surgical modification to resource grouping logic only

UI Structure

Resources Table:

  • Regular resources (containers, projects, executables, etc.) displayed normally
  • ▶ Parameters - Collapsed group row (auto-collapsed by default)
    • When expanded: Shows all individual parameter resources as children
  • All existing features work: filtering, search, sorting, details view, etc.

Implementation Notes

  • Parameters group uses existing collapse/expand infrastructure
  • No separate pages, tabs, or navigation needed
  • All filtering, search, and detail view functionality works unchanged
  • Minimal changes following surgical modification principles
  • The synthetic "Parameters" resource is created only when parameters exist

Fixes #6301

<issue_title>Suggestion: Separate Parameters from Active Resources in Aspire Dashboard</issue_title>
<issue_description>### Is there an existing issue for this?

  • I have searched the existing issues

Is your feature request related to a problem? Please describe the problem.

When running a DotNet Aspire application, the Aspire dashboard currently displays parameters alongside active resources in the Resources pane. While parameters are technically part of the configuration, they tend to be static and rarely change during runtime. Including them in the same view as dynamic resources creates unnecessary visual clutter and makes it harder to focus on the components that are actively running or interacting.

Describe the solution you'd like

Introduce a tabbed interface (or similar UI separation) within the Resources pane:

  • Running Resources Tab: Displays services, containers, and other runtime components.
  • Parameters Tab: Displays static configuration values and environment parameters.

This separation would improve clarity, reduce cognitive load, and make the dashboard more intuitive—especially for users monitoring live systems or debugging resource behavior.

Benefits:

  • Cleaner UI with better focus on runtime elements
  • Easier navigation and inspection of relevant components
  • Improved developer experience during debugging and monitoring

Pull Request Overview

This PR adds a dedicated Parameters page to the Aspire Dashboard, separating parameter resources from the active runtime resources for improved UI clarity. Parameters now appear in their own navigation tab, reducing visual clutter on the Resources page while maintaining full functionality.

Key changes:

  • Created a new Parameters page that reuses the existing Resources page structure but filters to show only parameter-type resources
  • Updated the Resources page to exclude parameters from both table and graph views
  • Added Parameters tab to desktop and mobile navigation menus between Resources and Console

The logger type should be ILogger<Parameters> not ILogger<Resources>. This will cause incorrect logger category names in telemetry and logging output.

Suggested change

The telemetry component ID should likely be a Parameters-specific identifier rather than TelemetryComponentIds.Resources. This will cause telemetry data from the Parameters page to be incorrectly attributed to the Resources page.

Suggested change
public ComponentTelemetryContext TelemetryContext { get; } = new(ComponentType.Page, TelemetryComponentIds.Resources);
public ComponentTelemetryContext TelemetryContext { get; } = new(ComponentType.Page, TelemetryComponentIds.Parameters);

The entire CSS file is duplicated from Resources.razor.css. Consider extracting shared styles into a common CSS file to avoid duplication and simplify future maintenance.

Removed CSS duplication in commit 333ba69. Parameters.razor.css has been deleted - the Parameters page now shares all styles with the Resources page through the existing Resources.razor.css file. Since both components use identical ::deep selectors that apply globally, no separate CSS file is needed for the Parameters page.

CSS duplication was already fixed in commit 333ba69 (my previous response). Parameters.razor.css has been completely removed - no duplication exists. The Parameters page now shares all styles from Resources.razor.css through Blazor's ::deep selectors.

This is the wrong approach. You should add a new tab inside the Resources.razor page, not an entirely new page for parameters @copilot

Encourage the AI @adamint 😄

@copilot you're doing so well and you're so smart! your approach is great but maybe we consider putting the parameters view inside the resources page instead?

I want to clarify the requirement before refactoring. Looking at the original instructions: "the dashboard has 3 top tabs on the main page (Table, Graph, Resources)" - should Parameters be a 3rd tab inside the Resources page (alongside Table and Graph), rather than a separate top-level navigation tab? If so, I'll refactor to move Parameters as a subtab within Resources.razor instead of a separate page.

Yes

Refactored in commit 692c6b4. Parameters is now a 3rd tab inside the Resources page (alongside Table and Graph tabs), not a separate page. The Parameters tab shows only parameter resources using the same grid UI, while Table and Graph tabs exclude parameters.

Structure:

  • Resources page → 3 tabs: Table | Graph | Parameters
  • Table/Graph: Show all resources except parameters
  • Parameters: Shows only parameter resources

All tests pass (83 tests). The approach is much simpler with no separate navigation, routes, or page infrastructure needed.

Ah, my instructions were unclear. I meant a new top tab, not a side tab. This is a whole other page:

I mean a new top selection next to "Table" and "graph" (then "Parameters") - can you take another crack at it @copilot ? the page itself looks good.

Can we make it a top level resource that is auto collapsed.

Reverted back to the original approach in commit 854e8af - Parameters is now a top-level navigation tab (like Resources, Console, Structured, etc.) in the main navigation sidebar, not a subtab within Resources.

Structure:

  • Main navigation: Resources | Parameters | Console | Structured | Traces | Metrics
  • Resources page has Table/Graph subtabs
  • Parameters page has Table/Graph subtabs
  • Each page filters appropriately (Resources excludes parameters, Parameters shows only parameters)

This matches the mockup screenshot you provided. All tests pass (84 tests).

@copilot No, that screenshot is of YOUR change. I do not want that. I want it to be a top tab, not a top-level tab - ie across the top of the top level "Resources" page.

Understood! Back to the correct approach - Parameters is now a horizontal tab across the top of the Resources page (alongside Table and Graph), not a separate page in the sidebar navigation.

Structure:

  • Sidebar navigation: Resources | Console | Structured | Traces | Metrics (unchanged)
  • Resources page horizontal tabs: Table | Graph | Parameters
  • Table/Graph: Show all resources except parameters
  • Parameters: Shows only parameter resources

This matches what was in commit 692c6b4. All tests pass (83 tests).

@copilot can you try @davidfowl 's suggestion - instead of a new tab, can you make Parameters a top level resource in the table with children resources for each param?

I'll implement @davidfowl's suggestion: create a top-level "Parameters" group row in the Resources table (auto-collapsed by default) with individual parameters as child rows underneath. This keeps everything in one table view without separate tabs or pages. Working on it now.

@copilot can you try @davidfowl 's suggestion - instead of a new tab, can you make Parameters a top level resource in the table with children resources for each param?

Implemented @davidfowl's suggestion in commit 3faa5dc: Parameters now appear as a top-level collapsible row in the Resources table (auto-collapsed by default) with individual parameters as child rows underneath.

Implementation:

  • Synthetic "Parameters" parent resource groups all parameter resources
  • Auto-collapsed by default to reduce clutter
  • Expand to see individual parameters
  • Uses existing parent-child and collapse/expand infrastructure

All tests pass (82 tests). This keeps everything in one table view with no separate tabs or pages needed.
