Hi Abhiman,

In this case use below code: 
  
public class ParamBlogController 
{
 private ApexPages.StandardController stdCtrl {get; set;}
  
 public List<position__c> conts {get; set;}
 public position__c pos {get;set;}
 
 public ParamBlogController(ApexPages.StandardController std)
 {
  stdCtrl=std;
  this.pos = (position__c)std.getRecord(); 
 }
  
 public void setupContacts()
 {
  conts=[select Name,city_state__c,Department__c,Position_Id__c,Position_Type__c from position__c where Position_Type__c=:pos.Position_Type__c and Location_Name__c=pos.Location_Name__c ];
 }
}

Thanks,

Hi Abhiman,

Try following.

Your Class: 
public with sharing class ParamBlogController 
{
public List<position__c> conts {get; set;}
 
 public ParamBlogController(){
     setupContacts();
 }
 
 public void setupContacts()
 {
   conts=[select Name,city_state__c,Department__c,Position_Id__c,Position_Type__c from position__c where Position_Type__c=:stdCtrl.getId()];
 }
}

VF Page:
  
<apex:page controller="ParamBlogController">
 <apex:outputPanel id="all">
  <apex:form >
    <apex:pageBlock title="Account Detail">
      <apex:pageBlockSection title="Account">
            
           
     
      </apex:pageBlockSection>
      <apex:pageBlockSection title="Contacts" columns="1">
        <apex:pageBlockTable value="{!conts}" var="cont" rows="10">
          <apex:column value="{!cont.Id}"/>
          <apex:column value="{!cont.Name}"/>
           <apex:column value="{!cont.city_state__c}"/>
          <apex:column value="{!cont.Position_Type__c}"/>
          
      
        </apex:pageBlockTable>
      </apex:pageBlockSection>
    </apex:pageBlock>
  </apex:form>
 </apex:outputPanel>
</apex:page>
Other changes you can make according to your requirements.

its not working properly. what exact u mean to say?
i try it but its not work

ThanksOnce you create a list at your Class by querying the object you just need your list at VF page like following  
<apex:pageBlockTable value="{!conts}" var="cont>

          <apex:column value="{!cont.Id}"/>

          <apex:column value="{!cont.Name}"/>

           <apex:column value="{!cont.city_state__c}"/>

          <apex:column value="{!cont.Position_Type__c}"/>
      

        </apex:pageBlockTable>
First you need to create a correct list at your Class.  This code is working for me.

you can debug your class data using system.debug(), and check is your list return the correct data or not in debug log.

anyway... what Error you are getting when you use my code ?

Hi Abhiman,

use below class code:  
public class ParamBlogController 
{
 private ApexPages.StandardController stdCtrl {get; set;}
  
 public List<position__c> conts {get; set;}
 public position__c pos {get;set;}
 
 public ParamBlogController(ApexPages.StandardController std)
 {
  stdCtrl=std;
  this.pos = (position__c)std.getRecord();

 
 }
  
 public void setupContacts()
 {
  conts=[select Name,city_state__c,Department__c,Position_Id__c,Position_Type__c from position__c where Position_Type__c=:pos.Position_Type__c];
 }
}

Please let me know if it helped or you need any more assistance.

Please mark this is as the solution if it solved your purpose.

Thank You,

in my position object i have this much fields and i want to insert records through the VF pages using Apex class.
in my position object i have two lookups fields one is positon_type__c and another is Location_Name__c when i want to insert records in position that time it will give me an error .

public class NextPage{
     private ApexPages.StandardController stdCtrl {get; set;}
     public List<position__c> conts {get; set;}
     public Position__c pos{get;set;}
    
    public NextPage(ApexPages.StandardController std) {
          stdCtrl=std;
          this.pos = (position__c)std.getRecord();
         }    
      
      public string position_type{get;set;}
      
 public String save() 
 {   
       Position__c newObj = new Position__c(); 
       newObj .position_type__c= [SELECT id FROM position_types__c WHERE Name =:pos.Position_Type__c LIMIT 1].id;
       insert newObj ;
       return 'success';
 }
 }

And this is my Apex class code
Sohan Raj GuptaSohan Raj Gupta
Hi Abhiman,

If positon_type__c is a lookup filed then it will give record ID apex class, so no need to get again ID in save function.

In save function you again create a new instance of Postion object and insert that. You should try below code:
  
public String save() 
 {   
       insert pos;
       return 'success';
 }
Try above code and if will face again issue then let me know.

Thanks,
Sohan Raj Gupta
