StandardSetController Class

StandardSetController objects allow you to create list controllers similar to, or as extensions of, the pre-built Visualforce list controllers provided by Salesforce.

Namespace

ApexPages

Usage

The StandardSetController class also contains a prototype object. This is a single sObject contained within the Visualforce StandardSetController class. If the prototype object's fields are set, those values are used during the save action, meaning that the values are applied to every record in the set controller's collection. This is useful for writing pages that perform mass updates (applying identical changes to fields within a collection of objects).

Fields that are required in other Salesforce objects will keep the same requiredness when used by the prototype object.

Note

Instantiation

You can instantiate a StandardSetController in either of the following ways:
  • From a list of sObjects:
  • From a query locator:

The maximum record limit for StandardSetController is 10,000 records. Instantiating StandardSetController using a query locator returning more than 10,000 records causes a LimitException to be thrown. However, instantiating StandardSetController with a list of more than 10,000 records doesn’t throw an exception, and instead truncates the records to the limit.

Note

Example

The following example shows how a StandardSetController object can be used in the constructor for a custom list controller:
The following Visualforce markup shows how the controller above can be used in a page:

StandardSetController Constructors

The following are constructors for StandardSetController.

StandardSetController(queryLocator)

Creates an instance of the ApexPages.StandardSetController class for the list of objects returned by the query locator.

Signature

public StandardSetController(Database.QueryLocator queryLocator)

Parameters

queryLocator
Type: Database.QueryLocator
A query locator representing a list of sObjects.

StandardSetController(controllerSObjects)

Creates an instance of the ApexPages.StandardSetController class for the specified list of standard or custom objects.

Signature

public StandardSetController(List<sObject> controllerSObjects)

Parameters

controllerSObjects
Type: List<sObject>
A List of standard or custom objects.

Example

StandardSetController Methods

The following are methods for StandardSetController. All are instance methods.

cancel()

Returns the PageReference of the original page, if known, or the home page.

Signature

public System.PageReference cancel()

Return Value

Type: System.PageReference

first()

Returns the first page of records.

Signature

public Void first()

Return Value

Type: Void

getCompleteResult()

Indicates whether there are more records in the set than the maximum record limit. If this is false, there are more records than you can process using the list controller. The maximum record limit is 10,000 records.

Signature

public Boolean getCompleteResult()

Return Value

Type: Boolean

getFilterId()

Returns the ID of the filter that is currently in context.

Signature

public String getFilterId()

Return Value

Type: String

getHasNext()

Indicates whether there are more records after the current page set.

Signature

public Boolean getHasNext()

Return Value

Type: Boolean

getHasPrevious()

Indicates whether there are more records before the current page set.

Signature

public Boolean getHasPrevious()

Return Value

Type: Boolean

getListViewOptions()

Returns a list of the listviews available to the current user.

Signature

public System.SelectOption getListViewOptions()

Return Value

Type: System.SelectOption[]

getPageNumber()

Returns the page number of the current page set. Note that the first page returns 1.

Signature

public Integer getPageNumber()

Return Value

Type: Integer

getPageSize()

Returns the number of records included in each page set.

Signature

public Integer getPageSize()

Return Value

Type: Integer

getRecord()

Returns the sObject that represents the changes to the selected records. This retrieves the prototype object contained within the class, and is used for performing mass updates.

Signature

public sObject getRecord()

Return Value

Type: sObject

getRecords()

Returns the list of sObjects in the current page set. This list is immutable, i.e. you can't call clear() on it.

Signature

public sObject[] getRecords()

Return Value

Type: sObject[]

getResultSize()

Returns the number of records in the set.

Signature

public Integer getResultSize()

Return Value

Type: Integer

getSelected()

Returns the list of sObjects that have been selected.

Signature

public sObject[] getSelected()

Return Value

Type: sObject[]

last()

Returns the last page of records.

Signature

public Void last()

Return Value

Type: Void

next()

Returns the next page of records.

Signature

public Void next()

Return Value

Type: Void

previous()

Returns the previous page of records.

Signature

public Void previous()

Return Value

Type: Void

save()

Inserts new records or updates existing records that have been changed. After this operation is finished, it returns a PageReference to the original page, if known, or the home page.

Signature

public System.PageReference save()

Return Value

Type: System.PageReference

setFilterID(filterId)

Sets the filter ID of the controller.

Signature

Type: Integer

Return Value

Type: Void

setSelected(selectedRecords)

Set the selected records.

Signature

public Void setSelected(sObject[] selectedRecords)

Parameters
