Visualforce Action Region Example.

Visualforce Action Region <apex:actionRegion> Example.

Hi,
In this post i am giving an example of <apex:actionRegion> usage in visualforce. it will use to achieve AJAX functionality to partial page refresh.

Controller Class:

public class ActionRegionCLS{

 public String reqAccNumber{get;set;}

 public Account accObj{get;set;}

 public ActionRegionCLS(){

  accObj = new Account();

 }

 public void fillRecord(){

  if(reqAccNumber !=null && reqAccNumber !=''){

    List<Account> accLst = new List<Account>();

    accLst = [select id,Name,AccountNumber,Type,AnnualRevenue from Account where AccountNumber =:reqAccNumber];

    if(accLst !=null && accLst.size()>0){

     accObj = accLst[0];

    }

    else{

   

     ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.Info,' No Records found with this Account Number:'+reqAccNumber);

     ApexPages.addMessage(myMsg);

     accObj  = null;

  

    }

  }

 }

 }

Visualforce Page :

<apex:page controller="ActionRegionCLS" >

 <apex:pagemessages id="msgs"></apex:pagemessages>

 <apex:form >

  <apex:pageblock id="pb">

   <table>

     <apex:actionRegion >

      <tr>

        <td> <apex:outputLabel value="Enter Account Number"> </apex:outputLabel> </td>

        <td>

        

         

          <apex:inputtext value="{!reqAccNumber}"/>

          <apex:commandButton value="Retrive" action="{!fillRecord}" rerender="pb,msgs"/>

          </td>

       </tr>  

     </apex:actionRegion>

     <tr>

      <td> <apex:outputLabel value="Account Name"> </apex:outputLabel> </td>

      <td>

        <apex:inputField value="{!accObj.Name}"/>

      </td>

     </tr>

     <tr>

     <td> <apex:outputLabel value="Account Type"> </apex:outputLabel> </td>

      <td>  <apex:inputField value="{!accObj.Type}"/> </td>

     </tr>

   </table>

  </apex:pageblock>

 </apex:form>

</apex:page>

Output :




once you enter account number value in Account Number text box and click on Retrive button it going to get the details of "Account Name", "Account Type" with out reloading entire page.using action region we are updating particular HTML area section with Rerender Tag.

          <apex:commandButton value="Retrive" action="{!fillRecord}" rerender="pb,msgs"/>

Visualforce Action Function Example.

Visualforce Action Function Example.

Hi, 
In this post i am giving an example of simple usage of <apex:actionFunction> tag in visualforce page to call a apex method from Java script.

Controller Class:

public class ActionFunctionCLS {

  public Account actObj{get;set;}

   PageReference prf= null;

    public ActionFunctionCLS(){

      actObj = new Account();

    }

 

   

    public pagereference Saverec(){

   if(actobj.Name !=''){

    insert actobj;

   

   }

   else{

     ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Error: Please Enter Name.');

     ApexPages.addMessage(myMsg);

   

   }

   if(actobj.id !=null){

  

      // Send the user to the detail page for the new account.

      prf = new PageReference('/'+actobj.id);

      prf.setRedirect(true);

   

   }

   return prf;

    }

}

Visualforce Page:

<apex:page controller="ActionFunctionCLS" id="pg" >

  <script>

   function recSave(){

    var accountType = document.getElementById('pg:fm:pb:pbs:actType').value;

    alert('accountType -->'+accountType);

    if(accountType != 'Prospect'){

     alert('You Should Select Prospect to Save the Record');

     return false;

    }

    else{

     saveAccount(); //this is the function name which calls our action function from java Script.

     return true;

    }

   }

 

  </script> 

 <apex:form id="fm">

  <apex:actionfunction name="saveAccount" action="{!Saverec}" />

   <apex:pageBlock id="pb">

     <apex:pagemessages ></apex:pagemessages>

     <apex:pageblockButtons >

      <apex:commandButton value="Save" onclick="recSave();return false;"/>    

     </apex:pageblockButtons>

    

     <apex:pageblockSection id="pbs">

       <apex:inputField value="{!actobj.Name}" id="actName"/>

       <apex:inputField value="{!actobj.type}" id="actType"/>

     </apex:pageblockSection>

   </apex:pageBlock>

 </apex:form>

</apex:page>

              

Once you select Account Type as "Prospect" Javascript method will call the <apex:actionfunction name="saveAccount" action="{!Saverec}" /> and controller method is going to execute.



That's it..
