  Name Description
Protected method BeginRender Called prior to the rendering of a control. In a derived adapter class, generates opening tags that are required by a specific target but not needed by HTML browsers. (Inherited from ControlAdapter.)
Protected method CreateChildControls Creates the target-specific child controls for a composite control. (Inherited from ControlAdapter.)
Protected method EndRender Called after the rendering of a control. In a derived adapter class, generates closing tags that are required by a specific target but not needed by HTML browsers. (Inherited from ControlAdapter.)
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method LoadAdapterControlState Loads any control state information that was saved by the SaveAdapterControlState method during a previous request to the page. (Overrides ControlAdapter.LoadAdapterControlState(Object).)
Protected method LoadAdapterViewState Loads adapter view state information that was saved by SaveAdapterViewState during a previous request to the page where the control associated with this control adapter resides. (Inherited from ControlAdapter.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method OnInit Registers the associated Menu control as one that requires control state. (Overrides ControlAdapter.OnInit(EventArgs).)
Protected method OnLoad Overrides the OnLoad method for the associated control. (Inherited from ControlAdapter.)
Protected method OnPreRender Handles the OnPreRender method for the associated Menu control. (Overrides ControlAdapter.OnPreRender(EventArgs).)
Protected method OnUnload Overrides the OnUnload method for the associated control. (Inherited from ControlAdapter.)
Protected method RaisePostBackEvent Used to maintain the path of the menu when a postback event is raised.
Protected method Render Generates the target-specific markup for the control to which the control adapter is attached. (Inherited from WebControlAdapter.)
Protected method RenderBeginTag Adds tag attributes and writes the markup for the opening tag of the control to the output stream emitted to the browser or device. (Overrides WebControlAdapter.RenderBeginTag(HtmlTextWriter).)
Protected method RenderChildren Generates the target-specific markup for the child controls in a composite control to which the control adapter is attached. (Inherited from ControlAdapter.)
Protected method RenderContents Writes the associated menu items in the associated Menu control to the output stream as a series of hyperlinks. (Overrides WebControlAdapter.RenderContents(HtmlTextWriter).)
Protected method RenderEndTag Creates final markup and writes the markup for the closing tag of the control to the output stream emitted to the browser or device. (Overrides WebControlAdapter.RenderEndTag(HtmlTextWriter).)
Protected method RenderItem Renders a single menu item as a hyperlink.
Protected method SaveAdapterControlState Saves any changes to the adapter private control state that have occurred since the page was posted back to the server. (Overrides ControlAdapter.SaveAdapterControlState().)
Protected method SaveAdapterViewState Saves view state information for the control adapter. (Inherited from ControlAdapter.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

  Name Description
Explicit interface implemetation Private method IPostBackEventHandler.RaisePostBackEvent Enables the MenuAdapter class to process an event raised when a page is posted back to the server.

A MenuAdapter modifies the markup or behavior of a Menu control for a specific browser or class of browsers, or acts as a filter on some capability.

By default, the MenuItem objects in the Menu control are rendered as hyperlinks to accommodate menu navigation. The Menu class maintains state by implementing the IPostBackEventHandler interface so that it can respond to and raise specific events during postback. You can extend the MenuAdapter class to further customize rendering or behavior of the Menu control.

The initial request for an adapter causes the .NET Framework to search for a mapped adapter for the control, given the characteristics of the requesting browser. The HttpBrowserCapabilities class uses browser definition files to identify the characteristics of the client browser and to map the adapter to the browser type.
