NoteNote

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;
}
