IdeaStandardController Class

IdeaStandardController objects offer Ideas-specific functionality in addition to what is provided by the StandardController.

Namespace

ApexPages

Usage

A method in the IdeaStandardController object is called by and operated on a particular instance of an IdeaStandardController.

The IdeaStandardSetController and IdeaStandardController classes are currently available through a limited release program. For information on enabling these classes for your organization, contact your Salesforce representative.

Note

In addition to the methods listed in this class, the IdeaStandardController class inherits all the methods associated with the StandardController class.

Instantiation

An IdeaStandardController object cannot be instantiated. An instance can be obtained through a constructor of a custom extension controller when using the standard ideas controller.

Example

The following example shows how an IdeaStandardController object can be used in the constructor for a custom list controller. This example provides the framework for manipulating the comment list data before displaying it on a Visualforce page.
public class MyIdeaExtension {
    
    private final ApexPages.IdeaStandardController ideaController;
    
    public MyIdeaExtension(ApexPages.IdeaStandardController controller) {
        ideaController = (ApexPages.IdeaStandardController)controller;
    }
    
    public List<IdeaComment> getModifiedComments() {
        IdeaComment[] comments = ideaController.getCommentList();
        // modify comments here
        return comments;
    }
    
}
The following Visualforce markup shows how the IdeaStandardController example shown above can be used in a page. This page must be named detailPage for this example to work.

For the Visualforce page to display the idea and its comments, in the following example you need to specify the ID of a specific idea (for example, /apex/detailPage?id=<ideaID>) whose comments you want to view.

Note

<!-- page named detailPage -->
<apex:page standardController="Idea" extensions="MyIdeaExtension">
    <apex:pageBlock title="Idea Section">
        <ideas:detailOutputLink page="detailPage" ideaId="{!idea.id}">{!idea.title}
        </ideas:detailOutputLink>
        <br/><br/>
        <apex:outputText >{!idea.body}</apex:outputText>
    </apex:pageBlock>
    <apex:pageBlock title="Comments Section">
        <apex:dataList var="a" value="{!modifiedComments}" id="list">
            {!a.commentBody}
        </apex:dataList>
        <ideas:detailOutputLink page="detailPage" ideaId="{!idea.id}" 
               pageOffset="-1">Prev</ideas:detailOutputLink>
        | 
        <ideas:detailOutputLink page="detailPage" ideaId="{!idea.id}" 
               pageOffset="1">Next</ideas:detailOutputLink>   
    </apex:pageBlock>
</apex:page>
