WebPartMenuStyle.MergeWith Method (Style)
This API supports the product infrastructure and is not intended to be used directly from your code.
Copies nonblank style elements to the WebPartMenuStyle instance, but does not overwrite existing style elements.
Assembly: System.Web (in System.Web.dll)
One reason this method overrides its base method is to customize the process of assigning a value to the ShadowColor property.
