Custom list view of case object using custom controller

• Display the custom list view of case object using visualforce page and custom controller.
• Here <apex:pageMessages/>'  tag is used to show message on page when no case founds in object.  And to display message, code is written in else block in constructor.

Visualforce Page:

<apex:page controller="CaseList" sidebar="false">

    <apex:pageMessages/>

    <apex:pageBlock>

        <apex:pageBlockTable value="{!lstCase}" var="c">

            <apex:column width="20px">

                <apex:facet name="header">Case Number</apex:facet>

                <apex:outputText value="{!c.CaseNumber}"/>

            </apex:column>

            <apex:column width="20px">

                <apex:facet name="header">Account Name</apex:facet>

                <apex:outputText value="{!c.Account.Name}"/>

            </apex:column>

            <apex:column width="20px">

                <apex:facet name="header">Contact Name</apex:facet>

                <apex:outputText value="{!c.Contact.Name}"/>

            </apex:column>

        </apex:pageBlockTable>

    </apex:pageBlock>

</apex:page>

Apex Class(Controller) :

public class CaseList

{

    public List<Case> lstCase{get;set;}

    public CaseList()

    {

        List<Case> caseList = [SELECT Id,CaseNumber,Account.Name,Contact.Name FROM Case order by createddate desc];

        if(caseList!=null && caseList.size()>0)

        {

            lstCase=caseList;

        }

        else

        {

            ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'No Case found.');

            ApexPages.addMessage(myMsg);

        }

    }

    

}
