Finding contacts for certain case

hi guys ,
i need help to devolp the code for finding contact from case list .
there will a picklist of cases we will have to choose a certain case and click on custom button find which will give contacts under that case 

thanks in advance 
Hi Rahul,

I am assuming it to be a VF page.
You may need to use here action function on change event of picklist field, through below JS script you can get the record id of case record that is selected which can be queried to get the contact associated with it.

Code Snippet I used  - 

<script> function getcaseId(elemid) {
var lkfield = document.getElementById(elemid + '_lkid').value;               --> gives u case record id
fetchCaseID(lkfield); }  

VF pape
<apex:actionFunction name="fetchCaseID" action="{!populateContact}" reRender="<contact display field> status="fetchCaseID"> <apex:param name="a" value="" assignTo="{!caseID}" /> </apex:actionFunction>
<apex:inputfield value="{!casepicklist}" onchange="getcaseId(this.id)" required="true"/>

public void populateContact()
            List<case> casecontact = [select <contact> from Case where id=:caseID];
           //logic to print this contact name in VF page back

let me know if you have any other issues here.
