visualforce tag

Most of the users have no clear idea about the usage of <apex:actionRegion> visualforce tag.In this post I will give a brief idea

<apex:actionRegion> :

         An area of a visualforce page that demarcates which components should be processed by the force.com server when an Ajax request is generated .

The <apex:actionRegion> component specifies the components to be processed on force.com server.If no <apex:actionregion> is defined the whole view functions as a region .
Here component means ,all visualforce tags like InputField,InputText,outputPanels etc.

Component processing includes

Conversion: converting from user inputted strings to date,numbers etc.
Validation :running validations like checking required fields.
model update :updating apex bindings i.e controller variables binded to visualforce page merge fields.


Note: Even when using <apex:region/>, the whole form is submitted but only part taken into region will be processed.

The example below will give an idea.

The following is the controller logic
public class regioncontroller {
    public String text1{ get; set; }
    public String text2{ get; set; }
}

The following is the visualforce page code.

<apex:page controller="regioncontroller ">
<apex:form >
   <apex:pageMessages id="messages1"/>
   <apex:pageBlock>
   <apex:pageBlockSection columns="2" >
      <apex:outputText value="name" />
      <apex:inputText value="{!text1}">
         <apex:actionSupport event="onkeyup" reRender="outname,messages1" />
      </apex:inputText>
      <apex:outputText value="Job" />
      <apex:inputText required="true" id="job2" value="{!text2}" />
   </apex:pageBlockSection>
<apex:outputText id="outname" style="font-weight:bold" value="Typed Name: {!text1}" />
</apex:pageBlock>
</apex:form>
</apex:page>


Now if u run the page and type something in the name textfield, u will get validation error because the entire form is submitted and everything in it goes for processing in server and since another inputtext field is made required,we are getting validation error as below

Now modify the visualforce page code as below

<apex:page controller="regioncontroller ">
<apex:form >
   <apex:pageMessages id="messages1"/>
   <apex:pageBlock>
   <apex:pageBlockSection columns="2" >
   <apex:actionRegion >
      <apex:outputText value="name" />
      <apex:inputText value="{!text1}">
         <apex:actionSupport event="onkeyup" reRender="outname,messages1" />
      </apex:inputText>
   </apex:actionRegion >
      <apex:outputText value="Job" />
      <apex:inputText required="true" id="job2" value="{!text2}" />
   </apex:pageBlockSection>
<apex:outputText id="outname" style="font-weight:bold" value="Typed Name: {!text1}" />
</apex:pageBlock>
</apex:form>
</apex:page>

Now when we run the page and type something in name text field,we will not get any validation errors because even though entire form is submitted,only the content present in <apex:actionRegion> will be sent for processing in server and  since no required field present in <apex:actionRegion> ,we donot get validation errors.The required field is present outside the <apex:actionRegion> .

How to access picklist values in Apex?

Sometimes we may have a requirement to get all the values of a picklist field in apex.
For example in account object ,active__c is a picklist field with values low,medium and high.
In this type of scenarios ,we need to use dynamic apex.

Dynamic apex allow us to interrogate a field or sObject, and  describe their characteristics.

The first thing we need to do, within our controller is use the getDescribe() method to obtain information on the  active__c  field:

Schema.DescribeFieldResult fieldResult = account.active__c.getDescribe();

We know that active__c is a picklist, so we want to retrieve the picklist values:

List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();

If we want to get picklist values in list do the following

 List<String> lstPickvals=new List<String>();

 for (Schema.PicklistEntry a : ple ) {
      lstPickvals.add(a.getValue());//add the value  to our list
   }
thats it,the lstPickvals  contains all the picklist field values 
i.e here low,medium,high.
 

 

How to display error message from trigger? (or) display validation error from trigger

We can display error messages from trigger.

field.addError(string):
     It places the specified error message on that field in the salesforce user interface and prevents any DML operation from occuring .
When used in visualforce controllers,if there is any inputfield component bound to field,the message is attached to the component.

This method is special because the field identifier is not actually the invoking object---the sobject record is the invoker.
 The following trigger example shows how to display error messages.

trigger testing2 on Account (after insert,after update) {

for (Account newOpp : Trigger.new) {
   
       newOpp .addError('See error  message will appear when u insert or update an account');
   

}
}

. 


  

How to activate or deactivate a trigger in production?

step1 :
              Open your eclipse IDE and choose your project.

step 2:
            choose the trigger which u want to activate or deactivate.Below that you can see xml file related to that trigger.for example  testtrigger-meta.xml  file.The xml file  looks like this

<?xml version="1.0" encoding="UTF-8"?>
<ApexTrigger xmlns ="http://soap.sforce.com/2006/04/metadata">
<apiVersion >24.0 </apiVersion>
<status>Active</status> ---->  change this to Inactive or active as u require.


</ApexTrigger>

step 3:
            In the xml tag you can set inactive or active as required.Then deploy the trigger to server.

        

SALESFORCEA

What is SalesforceA?


It is a mobile based admin application or administrators that allows them to take actions such as remotely resetting passwords, deactivating users and receiving information about scheduled maintenance from Salesforce.com. Now you can reset password while walking on road, traveling on bus/train.

Android:- https://play.google.com/store/apps/details?id=com.salesforce.chatter&hl=en

Functionality

Frozen Users
In Winter ’14 Salesforce introduced the “Freezing” function around a user which prevents that user from logging in, but isn’t deactivating them. This feature is useful if the user that needs to be deactivated is the default lead owner, has workflow rules, or an approval process associated to them. With The Salesforce Mobile Admin App this feature grows legs because now the Salesforce Admin on the go can quickly ‘freeze’ a user on their mobile device without the heavy lift of deactivating them. It’s almost like this feature was developed for the mobile app- and kudos for that.
Locked Out users
We all know that passwords and login attempts happen for users and they can lock themselves out. Having a locked out user can have an impact on key business functionality. With the Salesforce Mobile Admin App unlocking users is a couple taps away.

Viewing User Information

Viewing a User record is as simple as searching and tapping on Finally some fun returns to Salesforce and in this app it comes in the form of a rocket. Scrolling to the bottom of the homepage, holding the rocket till launches- opens the pillars of success for any Salesforce Admin: Ideas, User Groups, MVP Blog, Events, and Answers.the user. From the user record you can view and edit standard fields, reset the users password- how awesome is that- and assign permission sets. Having access to that many fields and that functionality is a game changer for any Admin who has had to wrestle a laptop out in an emergency and fuss with wifi to do those simple functions. The app also gives you the ability to view Login History- which is useful if HR or an executive is emailing you.

Permission Sets
This incredibly powerful and underused feature gets a spotlight in this app. Now your pre-defined permission sets can quickly be assigned or unassigned to a user. You can’t create a permission set yet in the app, so you will need to define your permission sets in the web interface. But having this ability again moves the power to manage your users from your desk to your pocket.


Release Notes
Critical to any Salesforce Admin’s day is the ability to quickly access the most recent release notes. With the Salesforce Mobile Admin app that is just 1 tap away from the home screen. Now, with over 300+ pages of release notes I don’t anticipate this being your only source to digest the notes, so I recommend using the search feature to find the topic that is of interest. But without a doubt, this features lets you respond to questions/ emails and keeps your laptop snuggled away.


Finally some fun returns to Salesforce and in this app it comes in the form of a rocket. Scrolling to the bottom of the homepage, holding the rocket till launches- opens the pillars of success for any Salesforce Admin: Ideas, User Groups, MVP Blog, Events, and Answers.

How to Use:

Once you Downloaded SalesforceA application from iTtune, double click on icon to open it, First time it will ask you to set the password, everytime you have to enter this passcode to access this application.

Now you are in, You can see  similar screen like below one .

 Launch the rocket and see the magic, it will open doors of success for you.Hold the rocket til launch.It will open Success community, Idea, User groups< MVP Blogs, Events and Answers Tab for you.

Batch processing

Batch Processing

why is it used?

 When there are large number of records(for ex thousands of records) to

process at a time,there may be problem of hitting governor limits.So,to avoid

this,we use batch processing in salesforce.

Advantage:

1)A large number of records can be processed.

2) Result of one batch cannot affect other batch.It means every batch is descrite.

How to use:

In order to use batch processing, first we need to create a class that implements

Database.Batchable<sObject> interface, then call that class in visualforce page.

Database.Batchable<sObject> interface has 3 methods

1) Global (Database.QueryLocator | Iterable<subject>)

 start(Database.BatchableContext bc){}

2)global void execute(Database.BatchableContext bc,list<p>){}

3) global void finish(Database.BatchableContext bc){}

The start() is used to get the records to be processed which are then passed as

parameter to execute().the processing is done in execute().

Finish() is used to send confirmation mails.

For example below is an example of processing all contacts and updating one

custom field in it to some value.

First is a class implementing the Database.Batchable<sObject> interface.

global class ContactReassignment implements Database.Batchable<sObject> {

 String query;

 String email;

 global Database.querylocator start(Database.BatchableContext BC) {

 query='Select id ,Rich_Text__c from Contact ';

 system.debug('QUERY'+query);

 system.debug('hai');

 return Database.getQueryLocator(query);

 }

 global void execute(Database.BatchableContext BC, List<sObject> scope) {

 system.debug('hai');

 system.debug('QUERY'+query);

 List<contact> accns = new List<contact>();

 for(sObject s : scope) {

 contact a = (contact)s;

 a.Rich_Text__c='testing';

 accns.add(a);

 }

 update accns;

 system.debug('#############3'+accns);

 }

 global void finish(Database.BatchableContext BC) {

 system.debug('hai');

 AsyncApexJob a = [SELECT Id, Status, NumberOfErrors,

JobItemsProcessed,

 TotalJobItems, CreatedBy.Email FROM AsyncApexJob WHERE Id

=:BC.getJobId()];

 system.debug('ksk'+a);

 String UserEmail = 'Any EMAIL';

Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

 mail.setToAddresses(new String[] {UserEmail});

 mail.setReplyTo('ANY EMAIL');

 mail.setSenderDisplayName('Batch Processing');

 mail.setSubject('Batch Process Completed');

 mail.setPlainTextBody('Batch Process has completed');

 Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });

 }

 Public Pagereference Updatecon() {

 ContactReassignment ACB = new ContactReassignment();

 Database.executeBatch(ACB);

 system.debug('***************'+ACB);

 return null;

 }

Next is the page calling that class.

<apex:page controller="ContactReassignment" action="{!Updatecon}">

 batch processing successful

</apex:page>

we can also schedule batch apex.

In order to schedule batch class,we need to write schedulable batch class

global class ContactReassignmentBatchSchedular implements schedulable
{
    global void execute(SchedulableContext sc)
    {
    ContactReassignment b = new ContactReassignment (); //ur batch class
     
        database.executebatch(b);
   }   
    
}

If u want to specify batch size,we can specify  in executebatch() as below

database.executebatch(b,100);

Once u wrote schedulable batch class,u need to schedule it as follows :

step 1:

Go to Setup--> develop--> apex classes

step 2:

click on  schedule   apex

step 3:

Here U can select schedulable batch class,date and time.

Thats it.Based on ur selection,the schedul apex runs..

How to escape special characters in formula?(or) How to escape special characters in javascript written in salesforce?

When we are writing  formulas or javascript code, if the values contains special symbols like aphostrope('),&(ampersand) etc sometimes we won't get expected results.

For example

account name contains O'Henry.Notice that  ' is a special character.When ever u r writing javascript if we write {!account.name}.It will give an error.



So to escape special symbols use JSENCODE function.


JSENCODE() :

                              Encodes text and merge field values for use in javascript by inserting escape characters ,such as a backslash( \ ), before unsafe javascript characters ,such as the apostrophe ( ' ).

Use:

              {!JSENCODE(text)}   and replace text with the merge field  or text string that contains the unsafe javascript characters
