SAIFAlphaNumericLinkControl¶

SAIFAlphaNumericLinkControl generates a row of 27 SAIFLinkButton link controls (A–Z plus a combined "0-9" numeric link), commonly used as an alphabetical index/jump bar above a list or grid.

Purpose¶

Provide a ready-made alphabet index bar so consuming pages do not need to hand-build 27 link controls and their click wiring.
Surface a single unified click event (LinkClicked) identifying which letter/number range was clicked, regardless of which of the 27 generated links triggered it.

Context¶

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

Public members¶

Member	Signature	Purpose
`LinkClicked`	`Public Event LinkClicked(Value As AlphaNumericCharacter)`	Raised when any generated letter/number link is clicked, passing the corresponding `AlphaNumericCharacter` value so host pages can filter their data accordingly.

Inherited public members¶

SAIFAlphaNumericLinkControl inherits from WebControl (System.Web.UI.WebControls), a framework base class rather than a documented SAIF dependency library.

Member	Signature	Purpose
`AccessKey`	`Public Property AccessKey As String`	Keyboard shortcut character used to move focus to the rendered link-bar container.
`Attributes`	`Public ReadOnly Property Attributes As AttributeCollection`	Collection of arbitrary HTML attributes rendered on the control's outer tag.
`BackColor`	`Public Property BackColor As Color`	Background color applied to the rendered outer element.
`ForeColor`	`Public Property ForeColor As Color`	Foreground (text) color applied to the rendered outer element.
`BorderColor`	`Public Property BorderColor As Color`	Border color applied to the rendered outer element.
`BorderStyle`	`Public Property BorderStyle As BorderStyle`	Border line style applied to the rendered outer element.
`BorderWidth`	`Public Property BorderWidth As Unit`	Border width applied to the rendered outer element.
`CssClass`	`Public Property CssClass As String`	CSS class name(s) rendered on the control's outer tag.
`Enabled`	`Public Property Enabled As Boolean`	Controls whether the generated link controls participate in enabled-state behavior.
`Font`	`Public ReadOnly Property Font As FontInfo`	Font styling applied to the rendered outer element.
`Height`	`Public Property Height As Unit`	Height of the rendered outer element.
`Width`	`Public Property Width As Unit`	Width of the rendered outer element.
`Style`	`Public ReadOnly Property Style As CssStyleCollection`	Inline CSS style declarations rendered on the outer tag.
`ToolTip`	`Public Property ToolTip As String`	Text shown as a native tooltip when hovering the rendered element.

Standard WebControl/Control members (ID, ClientID, Controls, Visible, DataBind, FindControl, etc.) are not re-documented here as they are unmodified framework behavior**.

Behavioral notes¶

CreateChildControls generates 26 SAIFLinkButton controls (A–Z, mapped from character codes 65–90) plus one additional link labeled "0-9" with Value = AlphaNumericCharacter.Number.
Each generated link's Click event is wired to a private handler that re-raises the public LinkClicked event with the clicked link's Value.

Constraints and usage notes¶

All 27 links post back individually; consuming pages must handle LinkClicked to filter or navigate based on the received AlphaNumericCharacter.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
