# SAIF.Presentation.Web.Controls.V2 overview

> **Documentation context:** Package-referenced (bundled via nuspec)
> **Documented via:** `SAIF.BOF.Presentation.Web.Infragistics103.nuspec` (repository root)

`SAIF.Presentation.Web.Controls.V2` is a presentation-tier ASP.NET WebForms custom-control library. It supplies thin subclasses of standard WebForms input controls, composite layout/chrome controls, site-wide banner chrome, and small cross-cutting UX helpers, all compiled directly into the `SAIF.BOF.Presentation.Web.Infragistics103` package assembly for reuse across SAIF WebForms applications.

## Purpose
- Provide a consistent, reusable set of ASP.NET WebForms server controls (input wrappers, layout/chrome, site banner, cross-cutting helpers) so consuming SAIF WebForms pages do not each reimplement common rendering conventions such as read-only image rendering, AJAX busy indicators, collapsible panels, and tab bars.
- Consumed directly by front-end SAIF WebForms applications and master pages that reference the `SAIF.BOF.Presentation.Web.Infragistics103` package.

## Responsibilities
- Render input-control wrappers with a consistent `[ReadOnly]` image-based rendering convention or AJAX "busy indicator" behavior on top of native WebForms controls.
- Manage composite layout/chrome controls (`SAIFPanel`, `SAIFTabBar`, `SAIFTabs`, `ConditionsGrid`, `SAIFGrid`) with `ViewState`-persisted collapsible/tab-selection state.
- Render site-wide banner chrome (`BannerControl`, `BannerControlV2`) by reading an external XML resource file, varying content by internal-vs-external client context.
- Supply narrowly scoped cross-cutting UX helpers (auto-focus scripting, control-enable-state tagging, duplicate-submit prevention, status-message iconography, alphabet index bar).

## Key components
- `BannerControl` / `BannerControlV2`: Site-wide banner rendering and logout flow, environment-conditional on internal/external client context.
- `SAIFPanel`: Collapsible content panel with `ViewState`-persisted expand/collapse state.
- `SAIFTabBar` / `SAIFTabs`: Two independent tab-bar implementations — declarative (markup-persisted) and imperative (code-driven), respectively*.
- `ConditionsGrid` / `SAIFGrid`: Composite grid controls for tabular presentation, including a UI-only medical-conditions column layout*.
- `SAIFCheckBox` / `SAIFCheckBoxList` / `SAIFRadioButton` / `SAIFRadioButtonList` / `SAIFDropDownList`: Input controls adding a shared `[ReadOnly]` static-image rendering convention.
- `SAIFButton` / `SAIFComboBox` / `SAIFListBox`: Input controls adding AJAX "busy indicator" client-side wiring.
- `MultiListControl`: TextBox + CheckBoxList combo picker with wildcard/mutual-exclusivity selection behavior.
- `SAIFMessage`: Status message control that auto-selects icon based on message-text keywords.
- `FocusManager`, `Utilities.mdlUtilities`, `OneClickSubmit`, `SAIFHoverHelp`, `SAIFAlphaNumericLinkControl`: Narrowly scoped cross-cutting UX helpers.
