Can I call another VF page from a VF page ?

I have a VF page ( VF page1)  that is using a extention Controller to display case history. I have another VF page ( VF page2 )  that will render a printable version of the Case history. I would like to add a command button ( <apex:commandButton) to allow VF page1 to call VF Page2. Is this possible or is there a better way to acomplish this?

Sorry, just realised that the first page should, of course, reference a standardController, not a controller...

 

 

i.e.

 

 <apex:page standardController="Case" extensions="MyExtension" >

Bind your button to a method that returns the PageReference for your second page...

 

e.g.

 


<apex:form>

  <apex:commandButton action="{!NavigateToPrintablePage}" value="Printable Page" />

</apex:form>
 
 
then in the controller for VF1,
 
 

public PageReference NavigateToPrintablePage() {

 PageReference pageRef = new PageReference('/apex/vf2');
 return pageRef;

}
 
Of course, you can use parameters to pass the Id of the Case to be rendered in your second page...
 
 
Hope this helps :)

Ian... Question please.... in your example how would I pass the case Id?
 
Thanks.

OK,
 
So I'm assuming you are passing an instance of the ApexPages.StandardController object in your extension constructor - you need to set your Controller to be 'Case' in your first Page
 

<apex:page controller="Case" extensions="MyExtension" >


</apex:page>
 
 
then in your extension class:
 

class MyExtension {

  private Case thisCase;

  public MyExtension(ApexPages.StandardController stdController) {
    thisCase = (Case)stdController.getRecord();
  }

  public PageReference NavigateToPrintablePage() {

    PageReference pageRef = new PageReference('/apex/vf2');

    pageRef.getParemeters().put('caseId', thisCase.Id);

    return pageRef;
  }

}
 
so you have put a parameter called 'caseId' into the page reference.
 
Then in the controller for your second page, you can use ApexPages.currentPage().getParameters().get('caseId') to retrieve the Case Id, which you can use to query the database and build your printable view,
 
 
HTH :)
