Resource summary

Question 1

Question
An HTML input element of type text. Use this component to get user input for a controller method that does not correspond to a field on a Salesforce object. This component does not use Salesforce styling. Also, since it does not correspond to a field, or any other data on an object, custom code is required to use the value the user inputs.
Answer
  • apex:messages
  • apex:dynamicComponent
  • apex:inputText
  • apex:inputField

Question 2

Question
A custom Visualforce component. All custom component definitions must be wrapped inside a single <apex:component> tag.
Answer
  • apex:includeScript
  • apex:commandLink
  • apex:dataTable
  • apex:component

Question 3

Question
A Visualforce chart. Defines general characteristics of the chart, including size and data binding.
Answer
  • apex:actionSupport
  • apex:inlineEditSupport
  • apex:chart
  • apex:enhancedList

Question 4

Question
A single piece of data in an <apex:pageBlockSection> that takes up one column in one row. An <apex:pageBlockSectionItem> component can include up to two child components. If no content is specified, the column is rendered as an empty space. If one child component is specified, the content spans both cells of the column. If two child components are specified, the content of the first is rendered in the left, "label" cell of the column, while the content of the second is rendered in the right, "data" cell of the column. Note that if you include an <apex:outputField> or an <apex:inputField> component in an <apex:pageBlockSectionItem>, these components do not display with their label or custom help text as they do when they are children of an <apex:pageBlockSectionItem>. Also note that <apex:pageBlockSectionItem> components cannot be rerendered; rerender the child components instead.
Answer
  • apex:flash
  • apex:pageBlockSectionItem
  • apex:outputField
  • apex:componentBody

Question 5

Question
The standard detail page for a particular object, as defined by the associated page layout for the object in Setup.

Answer
  • apex:pageblockSection
  • apex:component
  • apex:insert
  • apex:detail

Question 6

Question
A component that creates an inline frame within a Visualforce page. A frame allows you to keep some information visible while other information is scrolled or replaced.
Answer
  • apex:include
  • apex:iframe
  • apex:chartLabel
  • apex:attribute

Question 7

Question
Defines how labels are displayed. Depending on what component wraps it, <apex:chartLabel> gives you options for affecting labels for bar and line series labels, pie chart segments, and axes labels. Note: This component must be enclosed by a data series component (<apex:barSeries>, <apex:lineSeries>, or <apex:pieSeries>) or an <apex:axis> component.
Answer
  • apex:chart
  • apex:include
  • apex:chartLabel
  • apex:messages

Question 8

Question
A data series to be rendered as bars in a Visualforce chart. At a minimum you must specify the fields in the data collection to use as X and Y values for each bar, as well as the X and Y axes to scale against. Note: This component must be enclosed within an <apex:chart> component. You can have multiple <apex:barSeries> and <apex:lineSeries> components in a single chart.
Answer
  • apex:barSeries
  • apex:inputHidden
  • apex:outputLink
  • apex:outputField

Question 9

Question
This component provides inline editing support to <apex:outputField> and various container components. In order to support inline editing, this component must also be within an <apex:form> tag. The <apex:inlineEditSupport> component can only be a descendant of the following tags: <apex:dataList> <apex:dataTable> <apex:form> <apex:outputField> <apex:pageBlock> <apex:pageBlockSection> <apex:pageBlockTable> <apex:repeat> See also: the inlineEdit attribute of <apex:detail>
Answer
  • apex:inlineEditSupport
  • apex:chartLabel
  • apex:page
  • apex:outputPanel

Question 10

Question
A link to a JavaScript library that can be used in the Visualforce page. When specified, this component injects a script reference into the head element of the generated HTML page. For performance reasons, you may simply want to use a JavaScript tag before your closing <apex:page> tag, rather than this component.
Answer
  • apex:includeScript
  • apex:outputField
  • apex:attribute
  • apex:component

Question 11

Question
A section of data within an <apex:pageBlock> component, similar to a section in a standard Salesforce page layout definition. An <apex:pageBlockSection> component consists of one or more columns, each of which spans two cells: one for a field's label, and one for its value. Each component found in the body of an <apex:pageBlockSection> is placed into the next cell in a row until the number of columns is reached. At that point, the next component wraps to the next row and is placed in the first cell. To add a field from a Salesforce object to an <apex:pageBlockSection>, use an <apex:inputField> or <apex:outputField> component. Each of these components automatically displays with the field's associated label. To add fields for variables or methods that are not based on Salesforce object fields, or to customize the format of Salesforce object field labels, use an <apex:pageBlockSectionItem> component. Each <apex:inputField>, <apex:outputField>, or <apex:pageBlockSectionItem> component spans both cells of a single column.
Answer
  • apex:outputLabel
  • ex:actionPoller
  • apex:pageblockSection
  • apex:facet

Question 12

Question
A set of buttons that are styled like standard Salesforce buttons. This component must be a child component of an <apex:pageBlock>. Note that it is not necessary for the buttons themselves to be direct children of the <apex:pageBlockButtons> component—buttons that are located at any level within an <apex:pageBlockButtons> component are styled appropriately.
Answer
  • apex:includeScript
  • apex:commandButton
  • apex:pageBlockButtons
  • apex:form

Question 13

Question
A text area input element. Use this component to get user input for a controller method that does not correspond to a field on a Salesforce object, for a value that requires a text area.
Answer

  • apex:facet
  • apex:include
  • apex:attribute

Question 14

Question
A section of a Visualforce page that allows users to enter input and then submit it with an <apex:commandButton> or <apex:commandLink>. The body of the form determines the data that is displayed and the way it is processed. It's a best practice to verify that pages and custom components use at most one <apex:form> tag. As of API version 18.0, this tag can't be a child component of <apex:repeat>.
Answer
  • apex:form
  • apex:chart
  • apex:actionRegion
  • apex:insert

  • apex:chartTips

Question 18

Question
A button that is rendered as an HTML input element with the type attribute set to submit, reset, or image, depending on the <apex:commandButton> tag's specified values. The button executes an action defined by a controller, and then either refreshes the current page, or navigates to a different page based on the PageReference variable that is returned by the action. An <apex:commandButton> component must always be a child of an <apex:form> component. See also: <apex:commandLink>
Answer
  • apex:commandButton

Answer
  • apex:inputHidden
  • apex:iframe
  • apex:chartLabel
  • apex:logCallPublisher

Question 24

Answer
  • apex:inlineEditSupport
  • apex:insert
  • apex:outputLabel
  • apex:column

Question 26

Question
A definition of an attribute on a custom component. The attribute tag can only be a child of a component tag. Note that you cannot define attributes with names like id or rendered. These attributes are automatically created for all custom component definitions.
Answer
  • apex:attribute
  • apex:insert
  • apex:message
  • apex:include

Question 27

Question
An HTML input element for a value that corresponds to a field on a Salesforce object. The <apex:inputField> component respects the attributes of the associated field, including whether the field is required or unique, and the user interface widget to display to get input from the user. For example, if the specified <apex:inputField> component is a date field, a calendar input widget is displayed. When used in an <apex:pageBlockSection>, <apex:inputField> tags always display with their corresponding output label. Note that if custom help is defined for the field in Setup, the field must be a child of an <apex:pageBlock> or <apex:pageBlockSectionItem>, and the Salesforce page header must be displayed for the custom help to appear on your Visualforce page. To override the display of custom help, use the <apex:inputField> in the body of an <apex:pageBlockSectionItem>. Consider the following when using JavaScript events with this tag: For lookup fields, mouse events fire on both the text box and graphic icon For multi-select picklists, all events fire, but the DOM ID is suffixed with _unselected for the left box, _selected for the right box, and _right_arrow and _left_arrow for the graphic icons For rich text areas, no events fire.
Answer
  • apex:pageBlockButtons
  • apex:define
  • apex:outputLabel
  • apex:inputField

Question 28

Question
A link to a URL. This component is rendered in HTML as an anchor tag with an href attribute. Like its HTML equivalent, the body of an <apex:outputLink> is the text or image that displays as the link. To add query string parameters to a link, use nested <apex:param> components.
Answer
  • apex:inputField
  • apex:outputLink
  • apex:lineSeries
  • apex:emailPublisher

Question 29

Question
Displays text on a Visualforce page. You can customize the appearance of <apex:outputText> using CSS styles, in which case the generated text is wrapped in an HTML <span> tag. You can also escape the rendered text if it contains sensitive HTML and XML characters. This component does take localization into account. Use with nested param tags to format the text values, where {n} corresponds to the n-th nested param tag. The value attribute supports the same syntax as the MessageFormat class in Java. See the MessageFormat class JavaDocs for more information. Warning:Encrypted custom fields that are embedded in the <apex:outputText> component display in clear text. The <apex:outputText> component doesn't respect the View Encrypted Data permission for users. To prevent showing sensitive information to unauthorized users, use the <apex:outputField> tag instead.
Answer
  • apex:message
  • apex:actionSupport
  • apex:column
  • apex:outputText

Question 30

Question
A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover. See also: <apex:actionFunction>.
Answer
  • apex:form
  • apex:attribute
  • apex:page
  • apex:actionSupport

Question 31

Question

Answer
  • apex:image
  • apex:composition
  • apex:actionStatus
  • apex:componentBody

Question 32

Question
A component that inserts a second Visualforce page into the current page. The entire page subtree is injected into the Visualforce DOM at the point of reference and the scope of the included page is maintained. If content should be stripped from the included page, use the <apex:composition> component instead.
Answer
  • apex:iframe
  • apex:include
  • apex:inputFile
  • apex:inputField

Question 33

Question
Defines an axis for a chart. Use this to set the units, scale, labeling, and other visual options for the axis. You can define up to four axes for a single chart, one for each edge. Note: This component must be enclosed within an <apex:chart> component. This component is only applicable to bar and line charts.
Answer
  • apex:emailPublisher
  • apex:messages
  • apex:image
  • apex:axis

Question 34

Question
An area of a page that includes content from a second template page. Template pages are Visualforce pages that include one or more <apex:insert> components. The <apex:composition> component names the associated template, and provides body for the template's <apex:insert> components with matching <apex:define> components. Any content outside of an <apex:composition> component is not rendered.
Answer
  • apex:inputSecret
  • apex:composition
  • apex:pageblockSection
  • apex:lineSeries

Question 35

Question
A placeholder for content that is rendered in a specific part of the parent component, such as the header or footer of an <apex:dataTable>. An <apex:facet> component can only exist in the body of a parent component if the parent supports facets. The name of the facet component must match one of the pre-defined facet names on the parent component. This name determines where the content of the facet component is rendered. Consequently, the order in which a facet component is defined within the body of a parent component does not affect the appearence of the parent component. See <apex:dataTable> for an example of facets. Note: Although you can't represent an <apex:facet> directly in Apex, you can specify it on a dynamic component that has the facet. For example:
Answer
  • apex:logCallPublisher
  • apex:dataList
  • apex:inputField
  • apex:facet

Question 36

Question
A set of content that is grouped together, rendered with an HTML <span> tag, <div> tag, or neither. Use an <apex:outputPanel> to group components together for AJAX refreshes.
Answer
  • apex:outputPanel
  • apex:includeScript
  • apex:chartTips
  • apex:lineSeries

Question 37

Question
The email publisher lets support agents who use Case Feed compose and send email messages to customers. You can customize this publisher to support email templates and attachments. This component can only be used in organizations that have Case Feed and Email-to-Case enabled. Ext JS versions less than 3 should not be included on pages that use this component.
Answer
  • apex:pageBlock
  • apex:define
  • apex:component
  • apex:emailPublisher

Question 38

Question
An area of a Visualforce page that demarcates which components should be processed by the Force.com server when an AJAX request is generated. Only the components in the body of the <apex:actionRegion> are processed by the server, thereby increasing the performance of the page.
Answer
  • apex:outputLabel
  • apex:actionRegion
  • apex:facet
  • apex:emailPublisher

Question 39

Question
A link that executes an action defined by a controller, and then either refreshes the current page, or navigates to a different page based on the PageReference variable that is returned by the action. An <apex:commandLink> component must always be a child of an <apex:form> component. To add request parameters to an <apex:commandLink>, use nested <apex:param> components.
Answer
  • apex:dataList
  • apex:enhancedList
  • apex:commandLink
  • apex:include

Question 40

Question
A timer that sends an AJAX update request to the server according to a time interval that you specify. The update request can then result in a full or partial page update. You should avoid using this component with enhanced lists.
Answer
  • apex:dataList
  • apex:actionPoller
  • apex:inlineEditSupport
  • apex:image
