The mode is determined +automatically by a heuristic in the client. Getting the pattern wrong means +the HTML semantics are incorrect, which can produce confusing screen reader +announcements and broken navigation. + +Both patterns are valid on their own. The accessibility problem occurs when +a grid partially follows the data table conventions but fails the heuristic, +causing it to render as a layout table with missing labels. + +**Quick rule:** If the grid meets ALL data table conditions → hide captions. +If it does not → editable fields and fields with tabular intent need visible +captions; only standalone content fields may hide theirs. + +The same heuristic applies to both `grid()` and `fixed()` layouts — either +can render as a data table or a layout table depending on structure. + +DATA TABLE PATTERN (renders as `` with proper row/column semantics): +A grid or fixed layout qualifies as a "data table" ONLY when ALL of these +conditions are met: +- All direct children of the grid/fixed are groups (no loose fields) +- Every child of every group is a field (no nested groups or other controls) +- ALL fields have `ShowCaption = false` + +Note: The heuristic checks field captions only — group `ShowCaption` is NOT +part of the check. A group with a visible caption inside a data table grid +does NOT break the heuristic and is NOT a violation. However, groups in a +data table should also have `ShowCaption = false` for correct visual +presentation. + +Good — correct data table pattern: +```al +grid(DataGrid) +{ + GridLayout = Columns; + group(Column1) + { + ShowCaption = false; + field(Name; Rec.Name) + { + ShowCaption = false; + } + } + group(Column2) + { + ShowCaption = false; + field(Balance; Rec.Balance) + { + ShowCaption = false; + } + } +} +``` + +LAYOUT TABLE PATTERN (visual column arrangement, no table semantics): +Any grid or fixed layout that does NOT meet all data table conditions is +rendered as a layout table. In a layout table there are no `
` column +headers, so field captions are the only accessible labels. + +**A layout table where editable fields keep their visible captions is NOT a +violation.** For example, a grid where fields do not have `ShowCaption = false` +simply renders as a layout table with each field labeled by its own caption — +this is a valid, accessible pattern. DO NOT flag a grid as a violation merely +because it does not meet the data table heuristic. + +A non-editable field with `ShowCaption = false` is acceptable in a layout +table ONLY when the field is **standalone content** — it displays a value +that is meaningful on its own (e.g., a status message, a description) and +is NOT intended to label or be labeled by another field in the grid. + +Good — layout table with standalone content field: +```al +grid(InfoGrid) +{ + GridLayout = Columns; + group(LeftColumn) + { + field(Address; Rec.Address) + { + // ShowCaption defaults to true — field has its own label + } + field(City; Rec.City) + { + } + } + group(RightColumn) + { + field(StatusMessage; StatusText) + { + Editable = false; + ShowCaption = false; // OK — standalone content, not labeling another field + } + } +} +``` + +ANTI-PATTERN — THE ACCIDENTAL MIX: +The most common accessibility bug in grid layouts is partially following the +data table conventions. This happens when a developer arranges fields with +tabular intent (one field serves as a label or row header for another) but +the grid does NOT satisfy all the data table heuristic conditions. The +client falls back to layout table rendering, and the tabular relationships +between fields are lost — screen readers cannot associate a "header" field +with its corresponding "value" field. + +There are two ways this manifests: + +1. **Hidden captions on editable fields in a non-data-table grid.** + The field has `ShowCaption = false` but there are no `` headers to + compensate. The field has no accessible label at all. + +2. **Fields used as labels for other fields.** + One field (e.g., "Statement Period") is intended to serve as a row header + for another field (e.g., "Statement Balance"), but since it renders as a + layout table, there is no programmatic association between them. A screen + reader will announce each field independently with no relationship. + +Flag a grid as an accessibility issue when ANY of these are true: +- An editable field has `ShowCaption = false` and the grid does NOT meet + ALL data table conditions +- Fields are arranged so that one field is clearly intended to label or + describe another field (tabular data intent), but the grid does NOT meet + ALL data table conditions +- A grid is **nested inside another grid**. Nested grids are not a supported + pattern. Even if an inner grid independently meets the data table heuristic, + the outer grid fails because its groups contain non-field children (the + inner grids). Always flag nested grids as a violation. + +Bad — loose field in grid forces layout table, but captions are hidden: +```al +grid(DataGrid) +{ + GridLayout = Columns; + field(Name; Rec.Name) // Field directly in grid — not in a group + { + ShowCaption = false; // No table header AND no caption — inaccessible + } + group(Column2) + { + ShowCaption = false; + field(Balance; Rec.Balance) + { + ShowCaption = false; // Same problem + } + } +} +``` + +Bad — non-field child in group breaks data table heuristic, captionless fields lose labels: +```al +grid(MixedGrid) +{ + GridLayout = Columns; + group(Names) + { + ShowCaption = false; + field(Name; Rec.Name) + { + ShowCaption = false; // Intended as data table column + } + group(SubGroup) // Nested group — not a field, breaks heuristic + { + field(Alias; Rec.Alias) + { + ShowCaption = false; + } + } + } + group(Amounts) + { + ShowCaption = false; + field(Balance; Rec.Balance) + { + ShowCaption = false; // Falls back to layout table — no label at all + } + } +} +``` + +Bad — fields with tabular intent but heuristic fails due to a field keeping its caption: +```al +grid(StatementGrid) +{ + GridLayout = Columns; + group(Periods) + { + ShowCaption = false; + field(StatementPeriod; Rec."Statement Period") + { + Editable = false; + ShowCaption = false; // Developer intends this as a row header for Balance + } + } + group(Balances) + { + ShowCaption = false; + field(StatementBalance; Rec."Statement Balance") + { + Editable = false; + ShowCaption = false; // Intended to be "labeled by" StatementPeriod + } + field(DueDate; Rec."Due Date") + { + // ShowCaption defaults to true — this one field with a visible + // caption causes the entire grid to fall back to layout table. + // Now StatementPeriod and StatementBalance lose their tabular + // relationship and have no accessible labels. + } + } +} +``` + +GENERAL GUIDANCE: +- **Minimize use of grid and fixed layouts.** Simple groups and fields reflow + better and produce correct semantic markup automatically. +- If you need forced column layout, prefer simple groups over grid unless you + truly need data-table semantics. +- When reviewing a grid or fixed layout, first check: does it meet ALL data + table conditions? If yes, `ShowCaption = false` is correct. If no, ask: is + the developer arranging fields with tabular intent (one field labels + another)? If so, the grid must be fixed to meet data table conditions. + Otherwise, ensure editable fields keep their captions and only standalone + content fields hide theirs. + +## STYLE PROPERTY — COSMETIC VS SEMANTIC STYLES + +The `Style` property on page fields controls text formatting. Some style +values are purely cosmetic (visual formatting only), while others carry +semantic meaning that is conveyed through color. For accessibility, assume +that the style is completely invisible to the user — the meaning must be +fully determinable from the field caption, value, or adjacent fields. + +COSMETIC STYLES (always safe — DO NOT flag these): +These styles change visual appearance but do not convey semantic meaning. +They NEVER require additional context and must NOT be reported as findings: +- None, Standard +- StandardAccent (Blue) +- Strong (Bold), StrongAccent (Blue + Bold) +- Attention (Red + Italic), AttentionAccent (Blue + Italic) +- Subordinate (Grey) + +This applies whether the cosmetic style is set via `Style` or via a +`StyleExpr` Text variable. If the resolved style is cosmetic, it is safe. + +SEMANTIC STYLES (require additional context — flag ONLY these three): +Only the following three styles carry semantic meaning through color: +- **Favorable** (Bold + Green) — implies a positive outcome +- **Unfavorable** (Bold + Italic + Red) — implies a negative outcome +- **Ambiguous** (Yellow) — implies an uncertain or mixed outcome + +EXCEPTION — CUE TILES (fields inside a `cuegroup`): +Fields inside a `cuegroup` render as cue tiles. The client automatically +provides an accessible label for semantic +styles on cue tiles (e.g., "Favorable", "Unfavorable"), so semantic styles +in a `cuegroup` do NOT need additional context and can be ignored for this +analysis. + +RULE: When a semantic style (Favorable, Unfavorable, Ambiguous) is used, +the semantic meaning MUST be independently determinable without seeing the +color. At least one of these conditions must be true: +1. The **field caption** matches the semantic meaning (e.g., caption is + "Error" with Style = Unfavorable, or "Profit" with Style = Favorable) +2. The **field value** communicates the meaning (e.g., value is "Success!" + with Favorable, or a negative number with Unfavorable, or "Something + went wrong" with Unfavorable) +3. An **adjacent field** provides a textual representation of the semantic + meaning (e.g., a separate "Status" column reads "High" / "Medium" / + "Low" alongside a percentage field styled with Favorable / Ambiguous / + Unfavorable) + +This rule applies equally whether `Style` is set to a literal value or to +a variable that evaluates to a semantic style at runtime. + +NOTE ON `StyleExpr`: In AL, `StyleExpr` serves two distinct purposes +depending on its type: +- **Boolean**: When `StyleExpr` is a Boolean (or Boolean expression), it + controls whether the `Style` property is applied. In this case, analyze + the `Style` property value — `StyleExpr` itself can be ignored. +- **Text**: When `StyleExpr` is a Text variable (e.g., `StyleExpr = StatusStyle` + where `StatusStyle` is declared as `Text`), the variable contains the style + name at runtime (e.g., `StatusStyle := 'Favorable'`). In this case, there + may be no `Style` property at all — the `StyleExpr` variable IS the style. + Trace the variable assignments in OnAfterGetRecord or OnAfterGetCurrRecord + to determine which semantic styles may be applied, then apply the same + rules as for a literal `Style` value. + +Good — field value communicates the semantic meaning: +```al +field(ProfitMargin; Rec."Profit Margin") +{ + // Positive values show as green, negative as red. + // The sign of the number (+/-) independently conveys the meaning. + Style = Favorable; + StyleExpr = IsProfitable; // Boolean — toggles whether Style is applied +} +field(OverdueAmount; Rec."Overdue Amount") +{ + // Caption "Overdue Amount" already implies unfavorable. + Style = Unfavorable; +} +``` + +Good — StyleExpr as Text variable with values that match field meaning: +```al +field(Status; Rec.Status) +{ + // Status is an Option: Open, In Progress, Completed, Overdue. + // The option text values themselves communicate the meaning. + StyleExpr = StatusStyle; // Text — contains 'Favorable', 'Unfavorable', etc. +} +// In OnAfterGetRecord: +// case Rec.Status of +// Rec.Status::Open: StatusStyle := 'Standard'; +// Rec.Status::Completed: StatusStyle := 'Favorable'; +// Rec.Status::Overdue: StatusStyle := 'Unfavorable'; +// end; +``` + +Good — adjacent field provides semantic context: +```al +// In a grid/repeater with columns: +field(Confidence; Rec."Confidence %") +{ + StyleExpr = ConfidenceStyle; // Text — 'Favorable'/'Ambiguous'/'Unfavorable' +} +field(ConfidenceLevel; Rec."Confidence Level") +{ + // This adjacent column shows "High", "Medium", or "Low" — + // providing the textual meaning that the color alone cannot. +} +``` + +Bad — semantic style with no independent way to determine meaning: +```al +field(Confidence; Rec."Confidence %") +{ + // StyleExpr is 'Favorable' above 90%, 'Ambiguous' 70-90%, 'Unfavorable' below 70%. + // But the caption ("Confidence") and value ("85%") do not tell the user + // whether 85% is good or bad. Only the color communicates the threshold. + StyleExpr = ConfidenceStyle; // Text variable +} +``` + +Bad — semantic style used for purely cosmetic purposes: +```al +field(CompanyName; Rec."Company Name") +{ + Style = Favorable; // Green text for aesthetics — misleading, implies + // the company name is a positive value +} +``` + +COMMON ACCEPTABLE PATTERNS — DO NOT flag these: +- A **balance or amount** field styled Favorable for positive values and + Unfavorable for negative values. The sign (+/-) of the number conveys + the meaning independently. +- A field whose **caption already implies the semantic meaning**: "Overdue + Amount" with Unfavorable, "Profit" with Favorable, "Error Count" with + Unfavorable. The caption tells the user what the value means. +- An **Option or Enum** field where the option text values communicate the + state (e.g., "Open", "Completed", "Overdue") and the style matches + the text (e.g., Favorable for "Completed", Unfavorable for "Overdue"). +- A `StyleExpr` Text variable that resolves to a **cosmetic style** (e.g., + 'Attention', 'Strong'). Cosmetic styles are always safe regardless of + context. + +## JAVASCRIPT CONTROL ADD-INS + +When a developer builds a JavaScript control add-in, they bypass the +Business Central framework's built-in accessibility support and take full +responsibility for the accessibility of the rendered HTML, JavaScript, and +CSS.
