Standard List Controller Actions
Call action methods from page markup by using {! } notation in the action attribute of one of these tags.
- <apex:commandButton> creates a button that calls an action
- <apex:commandLink> creates a link that calls an action
- <apex:actionPoller> periodically calls an action
- <apex:actionSupport> makes an event (such as “onclick”, “onmouseover”, and so on) on another, named component, call an action
- <apex:actionFunction> defines a new JavaScript function that calls an action
- <apex:page> calls an action when the page is loaded
This table describes the action methods all standard list controllers support. You can associate these actions with any Visualforce component that includes an action attribute.
| Action | Description |
|---|---|
| save | Inserts new records or updates existing records that have been changed. After this operation is finished, the save action returns the user to the original page, if known, or to the home page. |
| quicksave | Inserts new records or updates existing records that have been changed. Unlike the save action, quicksave doesn’t redirect the user to another page. |
| list | Returns a PageReference object of the standard list page, based on the most recently used list filter for that object when the filterId isn’t specified by the user. |
| cancel | Aborts an edit operation. After this operation is finished, the cancel action returns the user to the page where they originally invoked the edit. |
| first | Displays the first page of records in the set. |
| last | Displays the last page of records in the set. |
| next | Displays the next page of records in the set. |
| previous | Displays the previous page of records in the set. |
In this example, the user specifies a filter to view account records.
<apex:page standardController="Account" recordSetVar="accounts">
<apex:form>
<apex:selectList value="{!filterid}" size="1">
<apex:selectOptions value="{!listviewoptions}"/>
</apex:selectList>
<apex:commandButton value="Go" action="{!list}"/>
</apex:form>
</apex:page>The page is associated with the standard Account list controller, which is based on the StandardSetController Apex class. The {!listviewoptions} expression calls the getListViewOptions() method for StandardSetController and evaluates to the available list views. The list view that the user selects is bound to the filterId property of the controller. When the filterId changes, the records available to the page change according to the filter. So when the user clicks Go, the standard list page displays the selected filtered records.
