Hii

You don't need to add trigger.isUpdate if you don't have any specific requirement 
this all code you can be replaced with mine 

    if(Trigger.isInsert){
        for(OpportunityLineItem objOppLineItem : Trigger.new){
            setOfOppLineItems.add(objOppLineItem.OpportunityId);
            oppIdToSet = objOppLineItem.OpportunityId;
        }
    }
    
    if(trigger.isDelete){
        
        for(OpportunityLineItem objOppLineItem : Trigger.old){
            setOfOppLineItems.add(objOppLineItem .OpportunityId);
            oppIdToSet = objOppLineItem .OpportunityId;
            
        }
    }
    
    //In this isUpdate only i am not getting what to do..
    if(trigger.isupdate){
        
        for(OpportunityLineItem objOppLineItem : Trigger.old){
          //  OpportunityLineItem objOppLineItemOldValue = Trigger.oldMap.get(objOppLineItem.Id);
            setOfOppLineItems.add(objOppLineItem .OpportunityId);
            oppIdToSet = objOppLineItem .OpportunityId;
            
        }
    }
  
// Here is My code 

List<OpportunityLineItem ​> allbulkdata = trigger.isdelete ? trigger.old : trigger.new ;

for(OpportunityLineItem objOppLineItem : allbulkdata ){
            setOfOppLineItems.add(objOppLineItem.OpportunityId);
            oppIdToSet = objOppLineItem.OpportunityId;
        }​


 I hope this will work fine if still, you have any problem let me know else mark as best 

Thank you

Hii Prem Chauhan
I write a trigger for you according to your scenarios you have to copy the code and use it 
Here I used three fields as per your requirements 
name as  Price1__c, Price2__c, Price2__c
and for their value Max_Price__c and Min_price__c
  
trigger OpporutinityPriceUpdate on Opportunity (after insert) {
    
    List<Opportunity> bulkOpp = new List<Opportunity>();
  
          for(Opportunity opp: Trigger.new)
          {
            if(opp.Price1__c !=NULL && opp.Price2__c !=NULL && opp.Price3__c !=NULL)
            {  
              Opportunity o = new Opportunity();
              o.Id = opp.Id;
              o.Name = opp.Name;  
              o.CloseDate  = opp.CloseDate;
              o.StageName =opp.StageName;
              
              if(opp.Price1__c >= opp.Price2__c && opp.Price1__c >= opp.Price3__c )
              {
                   o.Max_Price__c = opp.Price1__c;
                   if(opp.Price2__c <= opp.Price3__c )
                   {
                      o.Min_price__c = opp.Price2__c;
                   }else
                   {
                      o.Min_price__c = opp.Price3__c;
                   }
              }else if(opp.Price2__c >= opp.Price1__c && opp.Price2__c >= opp.Price3__c)
              {
                  o.Max_Price__c = opp.Price2__c;
                  if(opp.Price1__c <= opp.Price3__c )
                   {
                       o.Min_price__c = opp.Price1__c;
                   }else
                   {
                       o.Min_price__c = opp.Price3__c;
                   }
              }else
              {
                 o.Max_Price__c = opp.Price3__c;
                  if(opp.Price1__c <= opp.Price2__c )
                   {
                       o.Min_price__c = opp.Price1__c;
                   }else
                   {
                       o.Min_price__c = opp.Price2__c;
                   }
              }
            bulkOpp.add(o);
          }
        }
    
       if(bulkOpp.size()>0)
       {
           update bulkOpp;
       }
    
    
    
}

if you still have any problem then let me know and if this was good please don't forget to mark as best answer

Hii Prem 
You can also use this trigger they both are the same working .Chose any one you want cheer's 
trigger OpporutinityPriceUpdate on Opportunity (after insert) {
    
    List<Opportunity> bulkOpp = new List<Opportunity>();
    List<Double> priceList = new List<Double>();
  
          for(Opportunity opp: Trigger.new)
          {
            if(opp.Price1__c !=NULL && opp.Price2__c !=NULL && opp.Price3__c !=NULL)
            {  
              Opportunity o = new Opportunity();
              o.Id = opp.Id;
              o.Name = opp.Name;  
              o.CloseDate  = opp.CloseDate;
              o.StageName =opp.StageName;
               priceList.add(opp.Price1__c);
               priceList.add(opp.Price2__c);
               priceList.add(opp.Price3__c); 
               priceList.sort();
              o.Min_price__c = priceList[0];// after sort first index will be minmum 
              o.Max_Price__c = priceList[2];  // and last index will be maximum
              
            bulkOpp.add(o);
          }
        }
    
       if(bulkOpp.size()>0)
       {
           update bulkOpp;
       }
    
    
    
}

Hello Avaneesh !

        if(setOfOppLineItems.size() > 0){
          update listOfUpdatedOpp;
        }
        
    }
}

working of this code is :- when i add Product to their related object Opportunity then added product details will be shown in the below which is in Opportunity related List.
Have a look once for your reference.
insert and delete operation is working Fine but m lacking with isUpdate..
Thanks in Aadvance.

This is Position__CJob_Posting__c
When i click on new job Posting button it will ask me to select employment website when i select any one among multiple website then Price Per Post Maximum Budget  is added Automatically, when i do update for inserted job posting the fields on the position won't get update for that perticular position,
In this case also Update is not working.. i had tried previous code but dosen't work .. Don't know why ? 
AvaneeshAvaneesh
Hii
I think it should work but you can use debug Why this was not working but seems to look correct 
did you get any error 
Prem ChauhanPrem Chauhan
I din't get any error but fields on Position__c are not getting update,
Only related list is getting updated ..

Hii Avaneesh,
Will you able to solve my problem or not ??

Hi Prem,
i tried but I'm Stuck with your code didn't  get any solution post your code as a new Question somebody will definitely be resolved
