# ViewControlBase.PageModeEnum

`ViewControlBase.PageModeEnum` is the public nested enum that `ViewControlBase.PageMode` stores in the control's `ViewState`. It mirrors `ViewPageBase.PageModeEnum`'s intent but is a distinct, separately-declared type with a different member set — it has no `Insert` value and its member ordinals differ, so the two enums are not interchangeable despite sharing member names.

## Purpose
- Represents the interaction mode a user control is currently rendering (view, update, delete, print, PDF, or unknown), persisted across postbacks in the control's own `ViewState` via `ViewControlBase.PageMode`.
- Lets a control branch its rendering and validation logic independently of any page-level `PageModeEnum` value.

## Context
- Namespace: `SAIF.Presentation.Web.MVC`*
- Assembly/package: `SAIF.Presentation.Web.MVC`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| `View` | `View = 0` | The control is displaying data read-only |
| `Update` | `Update = 1` | The control is editing an existing record |
| `Delete` | `Delete = 2` | The control is confirming or performing a delete |
| `Print` | `Print = 3` | The control is rendering a print-oriented layout |
| `PDF` | `PDF = 4` | The control is rendering output destined for PDF generation |
| `Unknown` | `Unknown = 99` | No mode has been explicitly set; the default returned by `ViewControlBase.PageMode` before first assignment |

## Behavioral notes
- Unlike `ViewPageBase.PageModeEnum`, this enum has no `Insert` member, and its ordinal values are shifted down by one relative to `ViewPageBase.PageModeEnum` from `Delete` onward — casting a raw integer between the two enums would silently change meaning.

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