I know this is weird I can achieve this using Roll up summary .But what I want is to achieve this using trigger.
I want to write a trigger on Account ,which is having a field named Count__c .I want to autopopulate the nos of Contacts associated with that Account .
I have a situation,i want extended some of my standard controller property to my cusom controller ,when using my code i got following,here is my code anybody tell me ,where i did my mistake.
Code:
VF page:
<apex:page standardController="Account" extensions="myFirstController" showHeader="true" tabStyle="Account">
<apex:pageBlock title="Accounts">
<apex:form >
<apex:dataTable value="{!accountList}" var="account" cellpadding="4" border="1">
<apex:column >
<apex:commandLink >
<apex:outputText value="{!account.name}"/>
</apex:commandLink>
</apex:column>
</apex:dataTable>
</apex:form>
</apex:pageBlock>
<apex:pageBlock title="Contacts">
</apex:pageBlock>
</apex:page>
Code:
public class myFirstController{
public myFirstController(ApexPages.StandardController stdController){ }
public Account[] getAccountList() {
/* return [select id,name from Account where id = :System.currentPageReference().getParameters().get('id') ]; */
return [select id,name from Account limit 25];
}
public String getName()
{ return 'My First Custom Controller';
}
}
