AdornerProvider.Deactivate Method

Visual Studio 2010

Called when an adorner provider is about to be discarded by the designer.

Namespace: Microsoft.Windows.Design.Interaction
Assembly: Microsoft.Windows.Design.Interaction (in Microsoft.Windows.Design.Interaction.dll)

Syntax

C++

JScript

Copy

protected virtual void Deactivate()

Remarks

The Deactivate method is called before the adorners are removed from the designer user interface (UI).

Use the Deactivate method to detach event handlers which you attached earlier in the lifetime of the AdornerProvider.

An AdornerProvider instance may be activated and deactivated several times during its lifetime. Implement the Activate and Deactivate methods accordingly.

Examples

The following code example shows how to override the Deactivate method. For more information, see Walkthrough: Creating a Design-time Adorner.

Copy


// The following method deactivates the adorner.
protected override void Deactivate()
{
    adornedControlModel.PropertyChanged -= 
        new System.ComponentModel.PropertyChangedEventHandler(
            AdornedControlModel_PropertyChanged);
    base.Deactivate();
}
