visualforce auto fill based on lookup result

I want to present a summary of a child object on the VF screen of the parent.

On the parent I select the child using a lookup type input field and up on selection I want to show properties of the child on the screen in a summary div.

Any idea on how to do this?

Bill,

Investigate the Rerender attribute of the apex tag outputPanel. 

Using the outputPanel, along with re-render you can set it up to update the contents of the panel (essentially a div or span tag) when an action occurs. Your panel should display the details you want to display, and have it setup so that it's re-rendered whenever your lookupfield changes.

I am working with Bill on this.  We already tried that and the panel is not updated.  I had a status label hooked up to the output panel and it was saying it was called and completed, but nothing changed.  Here is the code:

<apex:page standardController="Booking__c" extensions="BookingExtensionController">
<h1>Booking for {!theBooking.Opportunity__r.Name} on {!theBooking.Opportunity__r.CloseDate}</h1>
  <apex:form >
      <apex:pageBlock >
          <apex:pageBlockSection title="Customer Information" columns="2">
              <apex:pageBlockSectionItem >
                  <apex:inputField id="contact" value="{!theBooking.Contact__c}">
                      <apex:actionSupport event="oncomplete"
                          rerender="customerInfo" />
                  </apex:inputField>
              </apex:pageBlockSectionItem>
              <apex:pageBlockSectionItem >
                  <apex:outputPanel id="customerInfo" rendered="true">
                      <h1>Provider Info</h1><br/>
                      {!theBooking.Contact__r.Name}<br/>
                      {!theBooking.Contact__r.MailingStreet}<br/>
                      {!theBooking.Contact__r.MailingCity}, {!theBooking.Contact__r.MailingState}  {!theBooking.Contact__r.MailingPostalCode}
                  </apex:outputPanel>
              </apex:pageBlockSectionItem>
          </apex:pageBlockSection>
      </apex:pageBlock>
  </apex:form>
</apex:page>


Public Class BookingExtensionController{
        
    public Booking__c theBooking { get; set;}
    private Apexpages.standardcontroller myController;
    
    Public BookingExtensionController(Apexpages.standardcontroller controller){
        myController = controller;
        
        List<String> fields = new List<String>();
        fields.add('Contact__c');
        fields.add('Contact__r');
        fields.add('Contact__r.Name');
        fields.add('Contact__r.MailingStreet');
        fields.add('Contact__r.MailingCity');
        fields.add('Contact__r.MailingState');
        fields.add('Contact__r.MailingPostalCode');
        fields.add('Opportunity__r');
        fields.add('Opportunity__r.Name');
        fields.add('Opportunity__r.CloseDate');
        myController.addFields(fields);
        
        this.theBooking = (Booking__c)myController.getRecord();
    }
}

I have been working on this and still have not solved it.  I have read MANY posts and I am at least to the point where my controller method is being called but I cannot get the ID of the contact selected to come through so I can load that contact.  I have completely rewritten this to start at the Opportunity level and here is the code.  WHAT AM I MISSING????


I have a custom Booking object that has a Contact field on it that is a lookup type to Contact.


<apex:page standardController="Opportunity" extensions="OpportunityExtension">
    <h1>Create booking for {!opportunity.Name} on {!opportunity.CloseDate}</h1>
    <apex:form >
        <apex:pageBlock >
            <apex:pageBlockSection title="Provider Information">
                <apex:actionRegion >
                    <apex:inputField value="{!theBooking.Contact__c}">
                        <apex:actionSupport event="onchange" action="{!updateContactInfo}" status="queryStatus" reRender="providerInfo">
                            <apex:param name="selectedContactId" value="{!theBooking.Contact__r.Id}" />
                        </apex:actionSupport>
                    </apex:inputField>
                </apex:actionRegion>
                <apex:outputPanel id="providerInfo">
                    Name: {!theContact.Name}<br/>
                </apex:outputPanel>
            </apex:pageBlockSection>
            <apex:pageBlockSection title="Dates">
                <apex:inputField value="{!theBooking.StartDate__c}"/>
                <apex:inputField value="{!theBooking.EndDate__c}"/>
            </apex:pageBlockSection>
        </apex:pageBlock>
      <apex:actionStatus id="queryStatus" startText="(Updating...)" stopText="(done)" />
    </apex:form>
</apex:page>


Public class OpportunityExtension
{
    public Booking__c theBooking { get; set;}
    public Contact theContact { get; set;}
    private Apexpages.standardcontroller myController;
    
    Public OpportunityExtension(Apexpages.standardcontroller controller){
        myController = controller;
        theBooking = new Booking__c();
    }
    
    Public void updateContactInfo() {
        String id = Apexpages.currentPage().getParameters().get('selectedContactId');
        system.debug('in updateContactInfo and about to load' + id);
        theContact = [SELECT Name FROM Contact WHERE Id = : id];
    }
}

fyi, I have also tried creating a property on the controller and using assignTo in the apex:param line but it was never set either.  I prefer NOT creating properties on my controller simply to pass method parameters.

P.S. fyi, I just tried entering a hard-coded contact ID and it worked just fine.  So my entire problem is getting the currently selected contact ID of the contact that was just selected in the search dialog.

I FIGURED IT OUT!!!  This works to update the Contact name field when a contact is selected.  Now to add more fields.

<apex:page standardController="Opportunity" extensions="OpportunityExtension">
    <h1>Create booking for {!opportunity.Name} on {!opportunity.CloseDate}</h1>
    <apex:form >
        <apex:pageBlock >
            <apex:pageBlockSection title="Provider Information">
                <apex:actionRegion >
                    <apex:inputField value="{!theBooking.Contact__c}">
                        <apex:actionSupport event="onchange" action="{!updateContactInfo}" status="queryStatus" reRender="providerInfo" />
                    </apex:inputField>
                </apex:actionRegion>
                <apex:outputPanel id="providerInfo">
                    Name: {!theContact.Name}<br/>
                </apex:outputPanel>
            </apex:pageBlockSection>
        </apex:pageBlock>
      <apex:actionFunction name="reQuery" action="{!updateContactInfo}" onComplete="rerenderprovider();">
          <apex:param name="contactId" value="{!theBooking.Contact__r.Id}" assignTo="{!selectedContactId}"/>
      </apex:actionFunction>
      <apex:actionFunction name="rerenderprovider" reRender="providerInfo" />
      <apex:actionStatus id="queryStatus" startText="(Updating...)" stopText="(done)" />
    </apex:form>
</apex:page>


Public class OpportunityExtension
{
    public Booking__c theBooking { get; set;}
    public Contact theContact { get; set;}
    private Apexpages.standardcontroller myController;
    
    Public OpportunityExtension(Apexpages.standardcontroller controller){
        myController = controller;
        theBooking = new Booking__c();
    }
    
    Public PageReference updateContactInfo() {
        theContact = [SELECT Name FROM Contact WHERE Id = :theBooking.Contact__c];
        return null;
    }
}
