Invalidate Method (DiagramLayout)

Declare that this layout might no longer be valid, depending on the change and the Conditions.

Syntax

public virtual void Invalidate( 
   LayoutChange reason,
   Part part
)

reason: A LayoutChange hint describing what change may have made the layout invalid. If the value is LayoutChange.All, ValidLayout will be set to false unconditionally.
part: the Northwoods.GoXam.Part that has changed

Remarks

This method may set ValidLayout to false, if the Conditions are met. This method does not request a new layout -- call InvalidateLayout if you want to unconditionally set ValidLayout to false and ask the Northwoods.GoXam.LayoutManager to schedule perform layouts that are invalid.
