# SAIFTabBarTab

`SAIFTabBarTab` is the serializable per-tab data model for `SAIFTabBar`, carrying the display text, ordering, selection, enabled/visible flags, and rendering hints (`AccessKey`, `Width`, `ToolTip`) that `SAIFTabBar.CreateChildControls` uses to build each tab's `LinkButton`.

## Purpose
- Hold the declarative, markup-persisted state for a single tab within a `SAIFTabBarTabCollection`.

## Context
- Namespace: `SAIF.Presentation.Web.Controls.V2`
- Assembly/package: Compiled into `SAIF.BOF.Presentation.Web.Infragistics103`*

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| `ID` | `Public Property ID As String` | Uniquely identifies the tab; defaults to a new GUID, and is used to match rendered `LinkButton`s back to their model during click handling. |
| `AccessKey` | `Public Property AccessKey As String` | Keyboard access key applied to the rendered tab's `LinkButton`. |
| `Enabled` | `Public Property Enabled As Boolean` | Controls whether the tab is clickable; disabled tabs render with `Disabled`/`DisabledSelected` CSS classes. Defaults to `True`. |
| `IsSelected` | `Public Property IsSelected As Boolean` | Indicates whether this tab is the currently active tab, driving `Selected`/`SelectedSibling` CSS classes. |
| `Key` | `Public Property Key As String` | Caller-assigned key for correlating the tab to external data; not used internally by `SAIFTabBar`'s own logic*. |
| `Order` | `Public Property Order As Integer` | Sort key used by `SAIFTabBarTabCollection.Sort` to order tabs before rendering. |
| `Text` | `Public Property Text As String` | The tab's display label. |
| `ToolTip` | `Public Property ToolTip As String` | Tooltip text applied to the rendered tab's `LinkButton`. |
| `Visible` | `Public Property Visible As Boolean` | Controls whether the tab renders at all; defaults to `True`. |
| `Width` | `Public Property Width As Unit` | Explicit width applied to the rendered tab's `LinkButton`. |
| `New()` | `Public Sub New()` | Constructs an empty tab model; `ID` still defaults to a new GUID via its own property initializer rather than constructor logic, so a tab is usable in a collection immediately after construction without further setup*. |

## Behavioral notes
- Decorated `<NotifyParentProperty(True)>` on most properties so changes made in the designer correctly propagate to the parent `SAIFTabBar`'s markup persistence.

## Constraints and usage notes
- `ID` must be unique within the owning `SAIFTabBar`'s `Tabs` collection, since `SAIFTabBar.Item`/`GetTabByID` look up tabs by this value.

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or
> contextual evidence where direct confirmation was not available in source artifacts.
