Historical Snapshot (Pre-Milestone 6): This audit was conducted before Milestones 6-8 which closed the majority of gaps listed below. For current status, see status.md and planning-docs/MILESTONE9-PLAN.md.

Generated: 2026-02-12 Auditor: Forge (Lead / Web Forms Reviewer) Scope: All 53 Web Forms controls audited against .NET Framework 4.8 API surface Source: Individual audit files in planning-docs/{Control}.md

Of 1,919 applicable features (properties + events), 1,314 fully match Web Forms behavior. An additional 54 exist but need API corrections. 551 features are missing entirely.

6 controls are 100% feature-complete. 2 controls are not started (Substitution, Xml). GridView is the weakest implemented control at 20.7% coverage.

PasswordRecovery has been merged to dev and the re-audit shows 73.7% health (42 matching features out of 57 applicable). DetailsView remains on the unmerged sprint3/detailsview-passwordrecovery branch.

• status.md incorrectly lists DetailsView as ✅ Complete
• DetailsView exists on the branch with 27 matching properties, 16 matching events, and strong CRUD support — but is inaccessible from the current working branch
• This means the actual shipped component count is 49/53 (92%), not 50/53 (94%)

Action Required: Merge DetailsView from sprint3/detailsview-passwordrecovery into dev.

DataBoundComponent<T> inherits BaseWebFormsComponent, not BaseStyledComponent. This means every data control that inherits DataBoundComponent<T> is missing all WebControl style properties:

• Affected controls (7): DataGrid, DetailsView, FormView, GridView, ListView, Chart*, Menu*
• Missing properties per control: BackColor, BorderColor, BorderStyle, BorderWidth, CssClass, Font, ForeColor, Height, Width, Style (~10 properties each)
• Exception: DataList implements IStyle directly — it has all style properties despite inheriting DataBoundComponent<T>

This single inheritance fix would close ~70 missing property gaps across 7 controls.

*Chart inherits BaseStyledComponent but not DataBoundComponent. Menu inherits BaseWebFormsComponent directly.

AccessKey is marked 🔴 Missing on every control that inherits BaseStyledComponent (and BaseWebFormsComponent). Web Forms WebControl.AccessKey maps to the HTML accesskey attribute. Adding this to BaseWebFormsComponent would close ~40 gaps at once.

ToolTip (renders as HTML title attribute) is missing from the base class. A handful of controls implement it directly (Button, Calendar, DataList, FileUpload, HyperLink, Image, ImageButton, ImageMap), but ~35 controls are missing it. Adding ToolTip to BaseWebFormsComponent would be a sweeping fix.

GridView has only 20.7% feature coverage — the lowest of any implemented control:

• No paging (AllowPaging, PageSize, PageIndex, PagerSettings, PagerStyle)
• No sorting (AllowSorting, SortDirection, SortExpression)
• No inline editing (EditIndex, EditRowStyle, RowEditing/RowUpdating/RowDeleting events)
• No selection (SelectedIndex, SelectedRow, SelectedRowStyle)
• No style properties (no BaseStyledComponent inheritance)
• Only 1 event implemented (RowCommand) out of 15 Web Forms events

GridView is the most commonly used data control in Web Forms applications. This is the single biggest migration blocker.

All 6 validator controls are missing the Display property (ValidatorDisplay enum: None, Static, Dynamic). This controls whether the validator reserves space in the layout (Static), collapses when valid (Dynamic), or is invisible (None — used with ValidationSummary). Without this, migrated pages will have layout differences.

Also missing across all validators: SetFocusOnError (focus management on validation failure).

ChangePassword, CreateUserWizard, Login, and PasswordRecovery all inherit BaseWebFormsComponent instead of BaseStyledComponent. They're missing BackColor, BorderColor, CssClass, Font, ForeColor, Height, Width, and Style (~8-10 properties each). Sub-element styles work via CascadingParameters, but the outer container cannot be styled.

Both Image and Label inherit BaseWebFormsComponent instead of BaseStyledComponent, despite Web Forms having them inherit WebControl. This makes them missing all 11 style properties (BackColor through Width). ImageMap was already fixed per team decision — Image and Label should follow.

Calendar has 9 style sub-properties (DayStyle, TitleStyle, etc.) implemented as CSS string parameters instead of TableItemStyle objects. This prevents cascading style inheritance and doesn't match the Web Forms API shape.

⚠️ DetailsView exists only on unmerged branch sprint3/detailsview-passwordrecovery

⚠️ DetailsView exists only on unmerged branch sprint3/detailsview-passwordrecovery

Both are intentionally deferred — Substitution is tied to ASP.NET output caching (no Blazor equivalent), Xml/XSLT is a legacy pattern.

These 6 controls match 100% of applicable Web Forms features:

Common theme: All 6 inherit from Control (not WebControl) in Web Forms, meaning they have no style properties by design. The Blazor implementations correctly mirror this with BaseWebFormsComponent inheritance.

Estimated total: ~180 gaps closed with 7 base class changes.

⚠️ CRITICAL: DetailsView Must Be Merged from sprint3/detailsview-passwordrecovery

PasswordRecovery has been merged and re-audited at 73.7% health. One component remains on the unmerged branch:

Component	Properties	Events	Tests	Gate Status
DetailsView	27 match, 23 missing	16 match, 2 missing	Referenced in Sprint 3	✅ APPROVED by Forge

Impact of NOT merging:

• status.md claims 50/53 (94%) but actual shipped count is 49/53 (92%)
• DetailsView features (strong CRUD events, auto-generated rows, edit mode) are inaccessible
• Any work on milestone4/chart-component branch diverges further from this component

Recommended action: Merge DetailsView to dev, then rebase current milestone branch.
