In Salesforce, How to call parametrized function from Visualforce?

Hi Tanu,

The <apex:param> standard component allows parameters to be defined for a parent component, which can be assigned to a controller property.

VF Page:-

<apex:commandButton value="Del" action="{!delCont}" rerender="all">
<apex:param name="contIdParam" value="{!cont.id}" assignTo="{!contIdChosen}"/>
</apex:commandButton>

Controller:-

public String contIdChosen {get; set;}

...

...

public PageReference delCont()
{
Contact toDel=new Contact(id=contIdChosen);
delete todel;
setupContacts();
return null;
}

Hope this will help you.

Thanks.
