Clears the properties and events from the cache.

Overloads

Refresh(Object)

Clears the properties and events for the specified component from the cache.
Refresh(Assembly)

Clears the properties and events for the specified assembly from the cache.
Refresh(Module)

Clears the properties and events for the specified module from the cache.
Refresh(Type)

Refresh(Object)

Source:
TypeDescriptor.cs
Source:
TypeDescriptor.cs
Source:
TypeDescriptor.cs

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

public:
 static void Refresh(System::Object ^ component);
public static void Refresh (object component);
static member Refresh : obj -> unit
Public Shared Sub Refresh (component As Object)

Parameters

component
Object

A component for which the properties or events have changed.

Examples

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

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.

TypeDescriptor.cs
Source:
TypeDescriptor.cs

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

public:
 static void Refresh(System::Reflection::Assembly ^ assembly);
public static void Refresh (System.Reflection.Assembly assembly);
static member Refresh : System.Reflection.Assembly -> unit
Public Shared Sub Refresh (assembly As Assembly)

Parameters

assembly
Assembly

The Assembly that represents the assembly to refresh. Each Type in this assembly will be refreshed.

Remarks

However, extender providers and designers can change the set of properties on an object. If they do, they can 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.

Before you make a call to the Refresh method to clear the cache, you need to call the GetProperties method for the specific assembly to cache the information first.

This method also raises a Refreshed event to notify all classes that want to be notified when the property set of a component changes.
