  <apex:form >
   <apex:actionFunction name="passValueToController" action="{!testvalues}" reRender="frm">
            <apex:param name="selectedValue" value="selectedValue" assignTo="{!selectedValue}"></apex:param>
        </apex:actionFunction>
  <apex:repeat value="{!wrapclasslist}" var="a" >
 
        <li style="padding:5px;cursor:pointer;" onclick="passValueToController('{!a.value}'); return false;" > 
                {!a.stateName}
            </li>
        </apex:repeat>
  
   
   <apex:outputPanel id="frm">
   
     statename is: <apex:inputText value="{!wrpclas.stateName}"/> <br/><br/>
   value is: <apex:inputText value="{!wrpclas.value}"/> <br/><br/>
    active is: <apex:inputText value="{!wrpclas.active}"/> <br/><br/>
   
    </apex:outputPanel>
    
  
  </apex:form>
</apex:page>

Apex class: 
public class testclass7 {
 public list<wrapperclass> wrapclasslist{get;set;}
 public list<wrapperclass> wrapclassaddedlist {get;set;}
 
  public wrapperclass wrpclas{get;set;}
  public string selectedValue{get;set;}
  
 public testclass7 (){
 wrapclasslist = new list<wrapperclass>();
 wrapclassaddedlist = new list<wrapperclass>();
     string  teststring= ' { "sucess":1,"data": [ {"stateName": "Andrapradesh",  "value": "apx" ,"active":"yes"}, { "stateName": "Telangana",  "value":"tsx","active":"processing-no"}, {"stateName": "Banglore",  "value": "bngx","active":"processing-yes"} , {"stateName": "Maharastra",  "value":"mhx" , "active":"no" }  ] } ';
     Map<String, Object> maptest =   (Map<String, Object>) JSON.deserializeUntyped(teststring);
     system.debug('Afterdeserilizing the values are:'+maptest);
     Object ob = (Object)maptest.get('data');
     system.debug('Afterdeserilizing get the data values are:'+ob);
     String srlze   = System.JSON.serialize(ob);
     system.debug('done serilization of the values:'+srlze);
     wrapclasslist = (list<wrapperclass>)System.JSON.deserialize(srlze,list<wrapperclass>.class);
     system.debug('After binding to the wrapper class the values is:'+wrapclasslist); 
 }
 
  /*
  public void testvalues(){
    system.debug('for Datatable functionality:'+ selectedValue);
    
    for(wrapperclass e: wrapclasslist){
      if(e.value==selectedValue){
      wrapclassaddedlist.add(e);
      
         }
     } 
     */

Hi deepika,
You are binding correctly but getting null values in vf page because you are not assigning any value to wrapclas in apex.So it is displaying as null.Assign value to wrapclas.then it will work.
I added a line in testvalues().Try below code 
public class testclass7 {
 public list<wrapperclass> wrapclasslist{get;set;}
 public list<wrapperclass> wrapclassaddedlist {get;set;}
 
  public wrapperclass wrpclas{get;set;}
  public string selectedValue{get;set;}
  
 public testclass7 (){
 wrapclasslist = new list<wrapperclass>();
 wrapclassaddedlist = new list<wrapperclass>();
     string  teststring= ' { "sucess":1,"data": [ {"stateName": "Andrapradesh",  "value": "apx" ,"active":"yes"}, { "stateName": "Telangana",  "value":"tsx","active":"processing-no"}, {"stateName": "Banglore",  "value": "bngx","active":"processing-yes"} , {"stateName": "Maharastra",  "value":"mhx" , "active":"no" }  ] } ';
     Map<String, Object> maptest =   (Map<String, Object>) JSON.deserializeUntyped(teststring);
     system.debug('Afterdeserilizing the values are:'+maptest);
     Object ob = (Object)maptest.get('data');
     system.debug('Afterdeserilizing get the data values are:'+ob);
     String srlze   = System.JSON.serialize(ob);
     system.debug('done serilization of the values:'+srlze);
     wrapclasslist = (list<wrapperclass>)System.JSON.deserialize(srlze,list<wrapperclass>.class);
     system.debug('After binding to the wrapper class the values is:'+wrapclasslist); 
 }
 
  /*
  public void testvalues(){
    system.debug('for Datatable functionality:'+ selectedValue);
    
    for(wrapperclass e: wrapclasslist){
      if(e.value==selectedValue){
      wrapclassaddedlist.add(e);
      
         }
     } 
     */
     
     
    public void testvalues(){
    system.debug('for Datatable functionality:'+ selectedValue);
    for(wrapperclass e: wrapclasslist){
      if(e.value==selectedValue){
       wrpclas = e;  //added this line
      system.debug(e);
     
      }
     }
  
  }
   public class wrapperclass{
   public string stateName{get;set;}
   public string value{get;set;}
   public string active{get;set;}
    
   }
}
Hope this helps you
