apex:dataList Component

The apex:dataList component in Salesforce Visualforce allows you to display a list of records in a customized format. This component is particularly useful when you want to display a list of records in a visually appealing manner.

Syntax

The basic syntax for using the apex:dataList component is as follows:

<apex:dataList value="{!records}" var="record">
  <!-- Child elements here -->
</apex:dataList>

Where:

• records is a variable containing the list of records to display.
• record is a variable used to reference each record in the list.

Example

Consider the following example where we will use the apex:dataList component to display a list of accounts:

<apex:dataList value="{!accounts}" var="acc">
  <div class="account-details">
    <p>Name: {!acc.Name}</p>
    <p>Industry: {!acc.Industry}</p>
    <p>Annual Revenue: {!acc.AnnualRevenue}</p>
  </div>
</apex:dataList>

In this example, we are using the apex:dataList component to display a list of accounts. For each account, we are displaying its name, industry, and annual revenue in a visually appealing format.

Output

The output of the above example would be a list of accounts with their details displayed in a customized format.

Explanation

The apex:dataList component works by iterating over the list of records passed to it and rendering the child elements for each record. In the example above, for each account in the list, we are displaying its details in a div element with a class of account-details. The fields of each account are accessed using merge field syntax.
