DesignSurface.BeginLoad Method (Type)

When rootComponentType is specified, a default designer loader that simply creates an instance of rootComponentType will be used. Designer loading can be asynchronous, so the loading may continue to progress after this call has returned. Attach an event handler to the LoadComplete event to be notified when the design surface has completed loading.

After BeginLoad is called, you can immediately obtain the view for the designer, because designer loaders must provide at least the root component when loading asynchronously.

Note
The BeginLoad method creates an instance of the component type and initializes a designer for this instance. The Loaded event is raised before this method returns.
