In your controller's SaveLeaves method, add a condition to validate the start and end date before resetting isEditable flag. — Raul, Jan 18, 2017 at 12:22
you dont want the record to be saved when there is an error? can you post your controller code? — Preya, Jan 18, 2017 at 12:24
can you edit your question to add the controller instead of posting answer — Preya, Jan 18, 2017 at 13:05

I feel below correction in code will help you to achieve what you desire:

   public Pagereference SaveLeaves(){
    integer counter=0;        
        for(WrapperClass w : listWrapper)
        {
           if(w.le.Start_Date__c >w.le.End_Date__c || w.le.End_Date__c<=system.TODAY() || w.le.Start_Date__c <=system.TODAY()){
                      listWrapper.get(opget).isEditable= false;}
                if(w.le.Start_Date__c >w.le.End_Date__c){
                    counter++;
                    listWrapper.get(opget).isEditable= false;

                    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.Error,'End Date should be greater than or equal to Start Date'));
                }
                if(w.le.End_Date__c<=system.TODAY()){
                    counter++;
                    listWrapper.get(opget).isEditable= false;

                    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.Error,'End Date should be greater than or equal to Today'));
                }
                if(w.le.Start_Date__c <=system.TODAY()){
                    counter++;
                    listWrapper.get(opget).isEditable= false;

                    ApexPages.addmessage(new ApexPages.message(ApexPages.severity.Error,'Start Date should be greater than or equal to Today'));                    
                }

        }
    if(counter==0){
        update listWrapper.get(opget).le;
    }
    else{
     return null;
     }

    // System.debug('Exception caught: ' + e.getMessage());

    system.debug('listWrapper.get(opget).le'+listWrapper.get(opget).le);
    listWrapper.get(opget).isSelected = false;
    listWrapper.get(opget).isEditable= false;
    return null;

}

Your code counts through counter variable for occurrences of errors. If counter is not zero it shoud return back and show the errors. Page state must not be changed in such cases.

See my code I changed the return type to pagereference from void. — Mukesh Verma, Jan 18, 2017 at 13:44
