How to make multiselect checkboxes in searched results of any Salesforce sObject?

Hi Pranav,

You have to create a Visualforce page to show data and you have to make controller for it to perform operation.

Here is Visualforce page:-
<apex:page standardController="Opportunity" extensions="OpportunityProductsearch">
<apex:form id="theForm">
<apex:pageBlock title="Search the Product" >
<apex:inputText value="{!searchtext}"/>
<apex:commandButton value="search" action="{!search}" />
<apex:pageMessages />
<apex:pageBlockSection Title="List of Product" id="table" collapsible="false" rendered = "{!toshow}">
<apex:pageBlockTable value="{!listofproductselected}" var="p" >
<apex:column title="Select" >
<apex:inputCheckbox value="{!p.checked}" ></apex:inputcheckbox>
</apex:column>
<apex:column headervalue="Name" value = "{!p.pro.Name}" />
<apex:column headervalue="Product Code" value="{!p.pro.ProductCode}"/>
<apex:column headervalue="Description" value="{!p.pro.Description}" />
</apex:pageBlockTable>
</apex:pageBlockSection>
<apex:commandButton value ="Submit" action ="{!submit}" rendered="{!toshow}" />
<apex:pageBlockSection Title="List of Product in Update" id="table2" collapsible="false" rendered = "{!!toshow}">
<apex:pageBlockTable value="{!showprod}" var="s" >
<apex:column headervalue="Name" >
<apex:inputField value = "{!s.Name}" />
</apex:column>
<apex:column headervalue="Product Code">
<apex:inputField value="{!s.ProductCode}"/>
</apex:column>
<apex:column headervalue="Description">
<apex:InputField value="{!s.Description}" />
</apex:column>
</apex:pageBlockTable>
</apex:pageBlockSection>
<apex:commandButton value ="save" action ="{!autoupdate}" rendered="{!!toshow}" />
<apex:commandButton value ="cancel" action ="{!search}" rendered="{!!toshow}" />
</apex:pageBlock>
</apex:form>
</apex:page>

and Now the Controller:-
public with sharing class OpportunityProductsearch {
public String searchText{get;set;}
public boolean toshow{get;set;}
public List<Product2> prod{get;set;}
public list<ProductWrapper> listofproductselected{get;set;}
public list<Product2> selectedproduct;
public list<Product2> showprod{get;set;}

public class ProductWrapper{
public Product2 pro{get;set;}
public Boolean checked{get; set;}
public ProductWrapper(Product2 p,boolean b){
pro = p;
checked = b;
}
}
public OpportunityProductsearch(ApexPages.StandardController con){
toshow = true;
prod = new List<Product2>();
prod.clear();
}
public void search(){
prod.clear();
toshow = true;
listofproductselected = new list<ProductWrapper>();

if(!String.isBlank(searchText)){
String s = '%'+searchText+'%';
prod =[select Name,ProductCode,Description,family from Product2 where name like :s ];

if(prod!=null){
for(Product2 p : prod){
ProductWrapper pw = new ProductWrapper(p,false);
listofproductselected.add(pw);
}
}
}
}
public void submit(){
toshow = false;
selectedproduct = new list<Product2>();
for(ProductWrapper p : listofproductselected ){
if(p.checked == true){
selectedproduct.add(p.pro);
}
}
System.debug('the select product to be printed : '+selectedproduct);
showprod = selectedproduct;
}
public void autoupdate(){
update showprod;
search();
}
}
