Get Data From Visualforce Controller Extension Without SOQL Query

Biswajeet   December 21, 2017   No Comments on Get Data From Visualforce Controller Extension Without SOQL Query

When a Visualforce page is loaded, the fields accessible to the page are based on the fields referenced in the Visualforce markup. But we can use StandardController.addFields(List fieldNames) method, which adds a reference to each field specified in fieldNames so that the controller can explicitly access those fields as well.

public with sharing class AccountControllerExt {
    public Account acc {get; set;}
    
    public AccountControllerExt(ApexPages.StandardController controller) {
        List<String> accFieldList = new List<String>();
        //Passing a list of field names to the standard controller
        controller.addFields(new List<String>{'Id', 'Name', 'AccountNumber', 'Website', 'Phone','Type', 'Industry'});
        //Standard controller to retrieve the field data of the record
        acc = (Account)controller.getRecord();
    }
}

Visualforce Pages with Lightning Experience Stylesheets

Biswajeet   December 20, 2017   No Comments on Visualforce Pages with Lightning Experience Stylesheets

In Winter’18 release, Salesforce has introduced lightningStylesheets attribute. To style the Visualforce page to match the Lightning Experience UI when viewed in Lightning Experience or the Salesforce app, We can set lightningStylesheets="true" in the apex:page tag. When the page is viewed in Salesforce Classic, it doesn’t get Lightning Experience styling.

Here is a standard Visualforce page with the lightningStylesheets="true" attribute in Classic View and Lightning View.

Visualforce Page:

<apex:page standardController="Account" lightningStylesheets="true">
    <apex:form> 
        <apex:pageBlock>
            <apex:pageblockButtons location="bottom">
                <apex:commandButton action="{!Save}" value="Save"/>
                <apex:commandButton action="{!Cancel}" value="Cancel"/>
            </apex:pageblockButtons>
            <apex:pageBlockSection columns="2" title="Create Account">
                <apex:inputField value="{!Account.Name}"/>
                <apex:inputField value="{!Account.AccountNumber}"/>
                <apex:inputField value="{!Account.Phone}"/>
                <apex:inputField value="{!Account.Website}"/>
                <apex:inputField value="{!Account.Type}"/>
                <apex:inputField value="{!Account.Industry}"/>                
            </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>

jQuery Data Tables in Visualforce Page

Biswajeet   December 15, 2017   2 Comments on jQuery Data Tables in Visualforce Page

Here is an example of ‎jQuery Data tables using in Visualforce. It will give you the pagination and search functionality in Visualforce page. Here I’m displaying list of account records.

Apex Class:

public class SampleController{
    public List<Account> accList {get; set;}
    
    public SampleController(){
    accList = [SELECT Name, AccountNumber, Phone FROM Account LIMIT 10000];
    }

}

Visualforce Page:

<apex:page Controller="SampleController" readOnly="true" tabStyle="Account" sidebar="false">
    <head>
        <apex:includescript value="//code.jquery.com/jquery-1.11.1.min.js"/>
        <apex:includescript value="//cdn.datatables.net/1.10.4/js/jquery.dataTables.min.js"/>
        <apex:stylesheet value="//cdn.datatables.net/1.10.4/css/jquery.dataTables.css"/>
        <script>
        j$ = jQuery.noConflict();
        j$(document).ready( function () {
            var accTable = j$('[id$="accTable"]').DataTable({
                
            });
        });
        </script>
    </head>
    <body>
        <table id="accTable" class="display">
            <thead>
                <tr>
                    <th>Name</th>
                    <th>Account Number</th>
                    <th>Phone</th>
                </tr>
            </thead>
            <tbody>
                <apex:repeat value="{!accList}" var="acc">
                    <tr>
                        <td>{!acc.Name}</td>
                        <td>{!acc.AccountNumber}</td>
                        <td>{!acc.Phone}</td>
                    </tr>
                </apex:repeat>
            </tbody>
        </table>
    </body>
</apex:page>
