Méthodes publiques

Méthode	Description
AddStatusMessage ( StatusMessageType type, string messageHtml ) : void	Add a status message of the given type to the status message collection. Message is not HTML-encoded. It is possible to have tags as part of the text.
GetDescendants ( Control control, bool>.Func predicate = null ) : IEnumerable	Standard Library use only.
SetContentContainer ( Control control ) : void	Notifies this page that only the form controls within the specified control should be checked for modifications and used to set default focus.
SetFocus ( Control control ) : void	Sets the focus to the specified control. Call this only during event handlers, and use the controlWithInitialFocus property instead if you wish to set the focus to the same control on all requests. Do not call this during LoadData; it uses the UniqueID of the specified control, which may not be defined in LoadData if the control hasn't been added to the page.

Méthodes protégées

Méthode	Description
EwfPage ( ) : System	Creates a new page. Do not call this yourself.
LoadPageStateFromPersistenceMedium ( ) : object	Loads hidden field state. We use this instead of LoadViewState because the latter doesn't get called during post backs on which the page structure changes.
OnInitComplete ( EventArgs e ) : void	Performs EWF activities in addition to the normal InitComplete activities.
OnPreInit ( EventArgs e ) : void	Executes EWF logic in addition to the standard ASP.NET PreInit logic.
OnPreRender ( EventArgs eventArgs ) : void
SavePageStateToPersistenceMedium ( object state ) : void	Saves hidden field state.
SaveViewState ( ) : object	Saves view state.
clearInfo ( ) : void	EWF use only.
createInfoFromNewParameterValues ( ) : PageInfo	Creates a page info object using the new parameter value fields in this page.
createInfoFromQueryString ( ) : void	Creates the info object for this page based on the query parameters of the request.
getPageViewDataModificationMethod ( ) : Action	Returns a method that executes data modifications that happen simply because of a request and require no other action by the user. Returns null if there are no modifications, which can improve page performance since the data-access cache does not need to be reset. WARNING: Don't ever use this to correct for missing loadData preconditions. For example, do not create a page that requires a user preferences row to exist and then use a page-view data modification to create the row if it is missing. Page-view data modifications will not execute before the first loadData call on post-back requests, and we provide no mechanism to do this because it would allow developers to accidentally cause false user concurrency errors by modifying data that affects the rendering of the page.
initEntitySetup ( ) : void	Loads the entity display setup for the page, if one exists.
loadData ( ) : void	Loads and displays data on the page. This is a replacement for the Init event that provides access to EWF page state.
