Hi,

 

Can you more elaborate that you want to display the pick list values from the existing picklist or just display lookup selected values in the picklist?Please let me know so that we can resolve the problem

Hi,

 

 

You can have picklist values based on your lookup field as, you have to write a action function in your code and you will have to call JavaScript function of action function on onselect of lookup field then this action will call a controller method in which you will have to add your picklist value in your selectoption list for your picklist based on lookup field value and then rerender your portion that belongs to your picklist field.

 

You can refer the below code 

 

// VF page

<apex:page controller="changemultipicklistvalue" id="page" >
<script>
function callonlookup(val)
{
   // alert('check'+val.value);
    callpicklistmethod(val.value);
    
}
</script>

  <apex:form id="frm" >
  <apex:inputField value="{!con.accountid}" id="lookup" onchange="callonlookup(this)"/>
  <apex:actionFunction name="callpicklistmethod" reRender="outputpanel1" action="{!changepicklistvalue}"><apex:param name="conid" value="" assignTo="{!lookupvalue}"/></apex:actionFunction>
  <apex:outputPanel id="outputpanel1" >
  <apex:selectList size="1" >
<apex:selectOptions value="{!options}"/>
  </apex:selectList>
  
  </apex:outputPanel>
  
  
  
  </apex:form>
</apex:page>

//Controller
public class changemultipicklistvalue
{
    public contact con{get;set;}
    public List<SelectOption> options{get;set;}
    public string lookupvalue{get;set;}
    
public changemultipicklistvalue()
{
    con=new contact();
     options = new List<SelectOption>(); 
     Schema.DescribeFieldResult F = contact.number__c.getDescribe();
      List<Schema.PicklistEntry> ple = f.getPicklistValues();
                     for( Schema.PicklistEntry f1 : ple)
                     {
                          options.add(new SelectOption(f1.getLabel(), f1.getValue()));
                     } 
}


public void changepicklistvalue()
{
    if(lookupvalue=='aa')
    {
        options = new List<SelectOption>(); 
        Schema.DescribeFieldResult F = contact.number__c.getDescribe();
        List<Schema.PicklistEntry> ple = f.getPicklistValues();
        for( Schema.PicklistEntry f1 : ple)
        {
                    if(integer.valueof(f1.getLabel())>5)
                    {
                     options.add(new SelectOption(f1.getLabel(), f1.getValue()));
                     }
        } 
    }
}

}
