Yes you can update opportunity stage picklist value on pageload using Action attribute of page tag call function from apex which will update.Note you can not perform this in constructor.

<apex:page  controller="Changestatus"   action="{!updatestatus}" >
=================================================================
 //function in Changestatus class
  
  public void updatestatus(){
     Id opportunityid;
    if(Apexpages.currentPage().getParameters().containsKey('opportunityid'))
       opportunityid= Apexpages.currentPage().getParameters().get('opportunityid');
    if(opportunityid!=null){
	      Opportunity opp=[Select Id,stage from opportunity where Id=:opportunityid];
	       if(opp!=null){
		       opp.stage='New status';
		       update opp;
	       }
	}

@Ajay This code update Opportunity record  Stage value, but my requirment is update the Stage picklist value. I replace Stage picklis value with custom value.
Ajay Nagar 7Ajay Nagar 7
Schema.DescribeFieldResult fieldResult = Opportunity.stage.getDescribe();
List<Schema.PicklistEntry> picklistEntries = fieldResult.getPicklistValues();
for(Schema.PicklistEntry pi: picklistEntries){
   if(pi.getValue()=='selected value')
   { pi.getValue()='updated value';
   }
 }
update picklistEntries;

Try this code.

@ Ajay When i run this code am getting error "Expression cannot be assigned"

Hi kumar tanwar,

This error is comming in line no 5 , i try to find out a way to assign this value but did not find any function or code to do so.As it is an ordered list you can try assigning this value using index of list in line no 5.

Thanks
Ajay
