Display modes are an integral part of Web Parts applications. When users switch to a different display mode on a Web page, the page will often take on a very different appearance, depending on the purpose of the new display mode. After a user initiates the process of changing to a new display mode by clicking a verb, you might want to make certain changes in the user interface (UI) by using the NewDisplayMode property to determine what the new display mode will be, and then changing various UI elements accordingly. A useful way to do this is to override the OnDisplayModeChanging method to customize the UI.
