Syntax

public event TabSwitchingEventHandler Switching;

Public Event Switching As TabSwitchingEventHandler

Comments

Occurs before another tab is selected.

The event can cancel the selection or redirect it to another tab. It also occurs when the SftTabs.SelectedIndex or SftTabs.SelectedTab property is set.

When the user switches tabs while a control on the current tab page has the input focus, that control is validated first. If validation fails, the tab is not switched and the Switching event does not occur.
