# SAIFTabEventArgs

Event args for `SAIFTabs` selection-change events, carrying the new tab, the previous tab, and a `Cancel` flag so handlers can veto the tab change.

## Purpose
- Lets a handler inspect both the incoming and outgoing tab and cancel the change before it takes effect.

## Context
- Namespace: `SAIF.Presentation.Web.Controls.V2`
- Assembly/package: `SAIF.Presentation.Web.Controls.V2` (packaged in `SAIF.BOF.Presentation.Web.Infragistics111.nuspec`)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| NewTab | `Public Property NewTab As TabSettings` | The tab being switched to. |
| PreviousTab | `Public Property PreviousTab As TabSettings` | The tab being switched away from. |
| Cancel | `Public Property Cancel As Boolean` | When set true by a handler, vetoes the pending tab change. |
