# PopUpButton

`PopUpButton` is a `System.Web.UI.WebControls.Button` subclass that wraps its own click in a client-side `confirm()` or `alert()` dialog before the postback proceeds, giving hosting pages a one-line way to add a "are you sure?" or informational dialog to any button without writing custom JavaScript ([OP-7](../../operations/popup-button-and-popup-control-generic-confirm-alert.md)).

## Purpose
- Add a client-side confirmation or notification dialog directly to a standard ASP.NET `Button` via markup properties, instead of requiring the hosting page to register its own script.
- Optionally block the postback entirely when the user cancels a `Confirm`-type dialog.

## Context
- Namespace: `SAIF.Presentation.Web.Controls.PopUps`
- Assembly/package: `SAIF.Presentation.Web.Controls.PopUps.Infragistics111` (package)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| `Message` | `Public Property Message() As String` | The text displayed in the client-side `confirm()`/`alert()` dialog |
| `PopupType` | `Public Property PopupType() As PopupTypes` | Selects whether the click wraps a blocking `confirm()` (`Confirm`) or a non-blocking `alert()` (`Notify`) |
| `PopupTypes` (nested enum) | `Public Enum PopupTypes` — members `Notify`, `Confirm` | Determines which client-side dialog behavior `Render()` emits |

## Inherited public members

Members in this section are inherited from `System.Web.UI.WebControls.Button` (a .NET Framework base class, not a documented SAIF library dependency). Standard `Button` members (`Text`, `Click`, `CommandName`, `CommandArgument`, `CausesValidation`, etc.) are available on this type through inheritance and are not re-documented here since their base is a BCL type outside this documentation set's scope.

## Behavioral notes
- `Render()` injects an `onclick` attribute — `return(confirm(Message))` for `PopupType = Confirm` (blocks postback on Cancel) or `alert(Message)` for `PopupType = Notify` (does not block postback) — before calling the base `Button.Render()`.

## Constraints and usage notes
- Because the dialog attribute is added directly to the rendered `<input type=submit>` element, any additional `onclick` handler set elsewhere on the page for the same button could conflict with the injected script*.

> **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.
