如何使用命令链接和输出链接重定向到新的VF页面？

Question

I have a list of Assets

Name:  column 2:  etc

A1      C1        b1
A2      c2        b2

When I click on A1, I call action="{! assetClicked}" within to do some logic, but I cannot redirect it to another Visual Force Page If I use I can link to another VF page, but cannot do action="{! assetClicked}"

Is there a way to combine them together or some other way around?

Page Code:

<apex:form >
  <apex:commandLink action="{! assetClicked}" value="{!wn.name}" id="theCommandLink"> 
    <apex:param value="{!wn.name}" name="id" assignTo="{!selectedAsset}" ></apex:param>
    <apex:outputLink value="/{!wn.id}" id="eventlink">{!wn.name}</apex:outputLink>
  </apex:commandLink> 
</apex:form>

Answer 1

You would need to use the PageReference class.

Here's a modified example from the documentation:

// selected asset property
public string selectedAsset {get;set;}

public PageReference assetClicked() 
{
    // Your code here

    PageReference redirect = new PageReference('/apex/PageName'); 

    // pass the selected asset ID to the new page
    redirect.getParameters().put('id',selectedAsset); 
    redirect.setRedirect(true); 

    return redirect;
}

Alternatively, you could use Page.PageName; instead of new PageReference('/apex/PageName'); as described here .

Answer 2

You didn't indicate how to retrieve the parameter in the desintation Visualforce page controller. I found this in a different forum:

// Assuming the parameter is 'id' after redirecting to page2 you can retrieve the paramter thus
public customcontrollerpage2() {
    String ID = ApexPages.currentPage().getParameters().get('id');
}

In button method add something like this at the end of the method:

PageReference pr = new PageReference('/apex/YOUR_PAGE_NAME');

return pr;
