@taani.ax1426 HI,
I read lots of things about standard list controller, but still coudn't understand logic behind that. Just understood one line from chapter VI, "Standard list controllers allow you to create Visualforce pages that can display or act on a set of records.".Couldn't find that whats the need and where it to be used.
Help me to understand.
Thanks,
taani
If i want to Display set of records in one object using vf page.
Without using controller we have to achive that functionality.
See this example....
<apex:page standardController="Account" recordSetVar="accounts" tabstyle="account" sidebar="false">
<apex:pageBlock >
<apex:pageBlockTable value="{!accounts}" var="a">
<apex:column value="{!a.name}"/>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:page>
And we can edit Multiple Opportunities records on a Single Page...
<apex:page standardController="Opportunity"
recordSetVar="opportunities"
tabStyle="Opportunity" sidebar="false">
<apex:form >
<apex:pageBlock >
<apex:pageMessages />
<apex:pageBlockButtons >
<apex:commandButton value="Save"
action="{!save}"/>
</apex:pageBlockButtons>
<apex:pageBlockTable value="{!opportunities}"
var="opp">
<apex:column value="{!opp.name}"/>
<apex:column headerValue="Stage">
<apex:inputField value="{!opp.stageName}"/>
</apex:column>
<apex:column headerValue="Close Date">
<apex:inputField value="{!opp.closeDate}"/>
</apex:column>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form>
</apex:page>
