Please copy the below code (as it is) in page "VFviewcontact" and see it it works


<apex:page standardcontroller="account" >
<apex:form >
   <apex:pageBlock title="Hello {!$User.FirstName}!">
      You are viewing the account.{!account.name}
   </apex:pageBlock>
   <apex:pageBlock title="Contacts">
      
      <apex:pageBlockTable value="{!account.contacts}" var="con">
              
      <apex:column value="{!con.Name}" />
         <apex:column value="{!con.Email}"/>
         <apex:column value="{!con.Phone}"/>
      </apex:pageBlockTable>
   </apex:pageBlock>
   </apex:form>
</apex:page>

Hi,

Just check you are using Acc in pageblock table but the visualforce page don't bind with controller in which  you have written acc in ViewContacts class. 
<apex:page Controller="ViewContacts" >
<apex:form >
   <apex:pageBlock title="Hello {!$User.FirstName}!">
      You are viewing the account.
   </apex:pageBlock>
   <apex:pageBlock title="Contacts">
      
      <apex:pageBlockTable value="{!acc}" var="con">
              
      <apex:column value="{!con.Name}" />
         <apex:column value="{!con.Email}"/>
         <apex:column value="{!con.Phone}"/>
      </apex:pageBlockTable>
   </apex:pageBlock>
   </apex:form>
</apex:page>

-Thanks

Hi,

After putting extension ="ViewContacts" same view its showing
Abhishek_DEOAbhishek_DEO
Tanya,
You don't need to use extension as you are not extending any standard controller in apex:page component. As AKG has mentioned, you should use Controller.

For eg. 
<apex:page Controller="ViewContacts" >

It should work

Hi abhishek,

Thanks for pointing out my mistake.It worked.

But I want it to be on Account object, which will redirect user to VF page populating all the contacts, associated with the Account.
That was the reason behind using standardController 

 
Abhishek_DEOAbhishek_DEO
Hi Tanya,

For that you don't need to write any extension/controller class. It all can be done with standard controller only. 
Look at below eg.

<apex:page standardcontroller="account" >
<apex:form >
   <apex:pageBlock title="Hello {!$User.FirstName}!">
      You are viewing the account.{!account.name}
   </apex:pageBlock>
   <apex:pageBlock title="Contacts">
      
      <apex:pageBlockTable value="{!account.contacts}" var="con">
              
      <apex:column value="{!con.Name}" />
         <apex:column value="{!con.Email}"/>
         <apex:column value="{!con.Phone}"/>
      </apex:pageBlockTable>
   </apex:pageBlock>
   </apex:form>
</apex:page>

To see the page, acces follwoing url: https://<yourserverURL>.visual.force.com/apex/<pagename>?id=00120000018cZJx

Remember, you have to pass an accountID as a paremeter in page

Hi Abhishek,

I have created a custom button on account detail page as "view contact" which will show all the contacts associated with it.

My VF page code is now :-
<apex:page standardController="Account" extensions="ViewContacts">
<apex:form >
   <apex:pageBlock title="Hello {!$User.FirstName}!">
      You are viewing the account.
   </apex:pageBlock>
   <apex:pageBlock title="Contacts">
   <apex:pageBlockButtons >
      <apex:commandButton value="Delete Contacts" action="{!Delete}"/>
   </apex:pageBlockButtons>
   
      <apex:pageBlockTable value="{!acc}" var="con">
              
      <apex:column value="{!con.Name}"/>
       <apex:column value="{!con.Email}"/>  
         <apex:column value="{!con.Phone}"/>
      </apex:pageBlockTable>
   </apex:pageBlock>
   </apex:form>
</apex:page>

Apex code being same as above.

Then also it is not fetching the data.

what URL you are accessing?

You have to pass an ID in URL

for eg. if page name is "showcontact" the it should be /showcontact?id=15digitaccountID

Also, you don't need to use any custom code(extension/controller). It can be achieved by using standard controller as I mentioned in my previous post. just use the same code.

account

This is wat its getting re-directed to
https://c.ap2.visual.force.com/apex/VFviewcontact?scontrolCaching=1&id=0012800000Ch52j

I even tried your way
https://c.ap2.visual.force.com/apex/VFviewcontact?id=0012800000Ch52j

Its giving same output as the screenshot above.

I am assuming that you are still using "ViewContacts" in your vf page. It has no use . To access related contact you can use relationship fields "{!account.contacts}"
