Apex Code:

public class  DisplayAllFieldsClass {
 
     public map<string,schema.sobjectfield> data {get;set;}
   
     public  DisplayAllFieldsClass (){
         data = Schema.SObjectType.BISWAJEET__Student__c.fields.getMap();
     }
}

Visualforce Page Code:

<apex:page doctype="html-5.0" showheader="false" controller="DisplayAllFieldsClass">
    <apex:datatable value="{!data}" var="d">
             <apex:column headervalue="Field Name">
                 {!d}
             </apex:column>         
         </apex:datatable>

<apex:page sidebar="false" id="TestPage">
    <p>Inner Visualforce Page Before</p>
        <apex:include pagename="TestChart"></apex:include>
    <p>Inner Visualforce Page After</p>
</apex:page>

Note: Here in above sample visualforce page “TestPage” is the main page and “TestChart” is another visulaforce page within “Testpage”.

Use of immediate attribute of commandbutton & commandlink in visualforce page.

Biswajeet April 30, 2015 No Comments

Basically we used immediate="true" in CommandButton & CommandLink, when we don’t want our validation rules to be fired during any server request.

It is a Boolean value that specifies whether the action associated with this component should happen immediately, without processing any validation rules associated with the fields on the page. If set to true, the action happens immediately and validation rules are skipped. If not specified, this value defaults to false.

We generally use it to make functionality of “Cancel” button or “Back” button, where we don’t want validation rule to get executed. If we don’t use immediate=true then on click of cancel button also, validation rules will get executed.

Here is the sample code:

<apex:commandlink action="{!cancel}" value="Cancel" styleclass="btn" id="btnCancel" immediate="true">
</apex:commandlink>

Here is an example to highlight the selected row in a page block table in visualforce page. To do this add the below code snippet to your visualforce page to highlight the selected row color among the rest of the rows in same page block table.

Visualforce Page:

<apex:page standardController="Account" recordSetVar="Accounts" sidebar="false" showHeader="false">  
    <apex:includeScript value="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"/>  
    <style>
        .ui-state-active{
        border: 1px solid #fbd850;
        background: rgb(199,199,199);
        font-weight: bold;
        color: #eb8f00;
        }
    </style> 
    <script>  
    function highlightRow(row){  
        $('tr').removeClass('ui-state-active');  
        $(row).parent().addClass('ui-state-active');  
    }  
    </script>  
    <apex:form >  
        <apex:pageBlock >  
            <apex:pageBlockTable value="{!accounts}" var="a">  
                <apex:column value="{!a.Name}" onclick="highlightRow(this)"/>  
                <apex:column value="{!a.AccountNumber}" onclick="highlightRow(this)"/>
                <apex:column value="{!a.Type}" onclick="highlightRow(this)"/>  
                <apex:column value="{!a.Industry}" onclick="highlightRow(this)"/>  
                <apex:column value="{!a.Phone}" onclick="highlightRow(this)"/>  
            </apex:pageBlockTable>  
        </apex:pageBlock>  
    </apex:form>    
</apex:page>

Output:

Note: If you want to change the Highlighted color, you can write your won style class.
