Jai Prakash Gupta count of checkboxes selected
Hi All,
I am new to coding and I have created a VF page with wrapper class and I want to count no of check box seleted.
VF Page:
<apex:page controller="myController2" sidebar="false">
<apex:form >
<apex:pageBlock >
<apex:pageBlockTable value="{!Pubs}" var="p" id="table">
<apex:column >
<apex:inputCheckbox value="{!p.selected}" onchange="updateSelectCount(this);"/>
</apex:column>
<apex:column value="{!p.con.Name}" />
<apex:column value="{!p.con.Type__c}" />
<apex:column value="{!p.con.Circulation__c}" />
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form>
</apex:page>
Class:
public class myController2 {
public list<pPublication> mypub{set;get;}
public List<pPublication> getPubs() {
if(mypub == null) {
mypub = new List<pPublication>();
for(Publication__c p: [select id,name,Circulation__c,Hit_Rate__c,Type__c from Publication__c limit 10 ]) {
mypub.add(new pPublication(p));
}
}
return mypub;
}
public PageReference processSelected() {
List<Publication__c> selectedPubs = new List<Publication__c>();
for(pPublication cPub: getPubs()) {
if(cPub.selected == true) {
selectedPubs.add(cPub.con);
}
}
for(Publication__c con: selectedPubs) {
system.debug(con);
}
mypub=null;
return null;
}
public class pPublication {
public Publication__c con {get; set;}
public Boolean selected {get; set;}
public pPublication(Publication__c p) {
con = p;
selected = false;
}
}
}
I am not able to count the selected checkboxes.
Please help.
Thanks in advance!!

public class myController2
{
public List<pPublication> lstPubs { get;set; }
public myController2()
{
lstPubs = new List<pPublication>();
for(Publication__c p: [select id,name,Circulation__c,Hit_Rate__c,Type__c from Publication__c limit 10 ])
{
lstPubs.add(new pPublication(p));
}
}
public PageReference processSelected()
{
List<Publication__c> selectedPubs = new List<Publication__c>();
for(pPublication cPub: lstPubs)
{
if(cPub.selected)
{
selectedPubs.add(cPub.con);
}
}
for(Publication__c con: selectedPubs)
{
system.debug(con);
}
/* Ypu can get selected checkbox count in 2 ways
1. Use selectedPubs.size()
OR
2. Use int variable and increment if cPub.selected == true
*/
system.debug('======selected Checkbox count====='+ selectedPubs.size());
// if you want to clear list then use : lstPubs.clear();
return null;
}public class pPublication
{
public Publication__c con {get; set;}
public Boolean selected {get; set;}
public pPublication(Publication__c p)
{
con = p;
selected = false;
}
}
}
But I want to display count of selected checkboxes at the top of the top of the page like 'Selected Checkboxes:4'(OutputTest) whenever any checkbox is selected to deselected.
For Example if I select 1 checkbox, it should display 1, when i select next checkbox it should update to 2.
Thanks in Advance!!
