Wizard.OnActiveStepChanged Method

Raises the ActiveStepChanged event.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

protected virtual void OnActiveStepChanged(
	Object source,
	EventArgs e
)

Parameters

source
Type: System.Object

The source of the event.

e
Type: System.EventArgs

An EventArgs that contains the event data.

The OnActiveStepChanged method raises the ActiveStepChanged event when the ActiveStep property of the Wizard control is changed. Use the ActiveStepChanged event to provide additional processing when the current step that is displayed in the Wizard control changes.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnActiveStepChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding the OnActiveStepChanged method in a derived class, be sure to call the OnActiveStepChanged method of the base class so that registered delegates receive the event.

The following code example demonstrates how to use the ActiveStepChanged event to update the HeaderText property of the Wizard control.

    Wizard1.HeaderText = "You are currently on " + Wizard1.ActiveStep.Title;
  }
