The DesignerEventArgs type exposes the following members.

Public methodDesignerEventArgsInitializes a new instance of the DesignerEventArgs class.

Public propertyDesignerGets the host of the document.

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)

The DesignerCreated and DesignerDisposed events are raised when a document is created or disposed of.


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following example demonstrates creating a DesignerEventArgs.

// This example method creates a DesignerEventArgs using the specified designer host. 
// Typically, this type of event args is created by the IDesignerEventService.   
public DesignerEventArgs CreateComponentEventArgs(IDesignerHost host)
    DesignerEventArgs args = new DesignerEventArgs(host);

    // The designer host of the created or disposed document:  args.Component 

    return args;
