Hi,

You can use the following code for the reference in your Apex class of the VF page

 

list<invoice> invoiclist=[select amount from invoice];
integer sum=0;
if(invoiclist.size()>0)
{
for(invoice inv:invoiclist)
{
if(inv.amount!=null)
{
sum=sum+inv.amount;
}
}
}

 

Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.

How to add this list information in visualforce page? which component is used

Hi,

 

Hi,

If you want to display the list information on the page you can either <apex:pageblocktable> or<apex:repeat>

Example of <Apex:pageblocktable>

 

<apex:pageBlockTable value="{!invoiclist}" var="invoiclistobj">

 <apex:column ><apex:facet name="header">Amount</apex:facet> {!invoiclistobj.amount}</apex:Column>

 

 </apex:pageBlockTable>

  </apex:pageBlock>

 

 

You can print the value of “sum property using the <apex:outputtext> on VF page

 

For example

 

<apex:outputText value="{!sum}"></apex:outputText>

Take a look at summary formula fields which you could use to create a total field on the invoice object.  Then you wouldn't need any apex code....
