ComponentEventArgs is the root event arguments class for all component management events. This type of event occurs when you add or remove components using a designer.

Note Note

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 ComponentEventArgs.

C#
C++
VB
Copy 

// This example method creates a ComponentEventArgs using the specified argument.
// Typically, this type of event args is created by a design mode subsystem.  
public ComponentEventArgs CreateComponentEventArgs(IComponent component)
{
    ComponentEventArgs args = new ComponentEventArgs(component);

    // The component that is related to the event:  args.Component

    return args;
}
