TypeDescriptor.Refresh Method (Object)

Clears the properties and events for the specified component from the cache.

Namespace: System.ComponentModel
Assembly: System (in System.dll)

Syntax

Visual Basic

Public Shared Sub Refresh ( _
	component As Object _
)

public static void Refresh(
	Object component
)

Visual C++

public:
static void Refresh(
	Object^ component
)

static member Refresh : 
        component:Object -> unit

Parameters

component: Type: System.Object
A component for which the properties or events have changed.

Remarks

Properties and events are cached by TypeDescriptor for speed. Typically, they are constant for the lifetime of an object. However, extender providers and designers can change the set of properties on an object. If they do, they should call this method to clear the property and event descriptors of the object. This method is used only at design time. It is not used during run time.

This method also raises a Refreshed event when the properties or events of a component change. This event is only raised if there was a prior call to the GetProperties or GetEvents method that cached the information.

Examples

For an example of using this method, see the RefreshEventHandler class.
