please help me very ugent.

Try instantiating your selectedAccounts and categories in the contructor instead of doing it every time you call ProcessSelected method and getCategories:
You can also create another Case list to prevent updating records repeatedly:
Apex:
public class PagingControllerforCase { public List<CategoryWrapper> wrapaccountList { get; set; } List<CategoryWrapper> categories {get;set;} public List<Case> selectedAccountsToUpdate{get;set;} public List<Case> selectedAccounts{get;set;} public Set<Case> setSelectedAcc {set;get;} // instantiate the StandardSetController from a query locator public PagingControllerforCase() { setSelectedAcc=new Set<Case>(); // Instatiate here selectedAccounts=new List<Case>(); categories = new List<CategoryWrapper>(); wrapaccountList =new List<categoryWrapper>(); for(Case a:[SELECT Id FROM Case LIMIT 10]){ wrapaccountlist.add(new categoryWrapper(a)); } } public ApexPages.StandardSetController con { get { if(con == null) { con = new ApexPages.StandardSetController(Database.getQueryLocator([SELECT Id FROM Case LIMIT 100])); // sets the number of records in each page set con.setPageSize(5); } return con; } set; } // returns a list of wrapper objects for the sObjects in the current page set public List<categoryWrapper> getCategories() { for (Case category : (List<Case>)con.getRecords()) categories.add(new CategoryWrapper(category)); return categories; } // indicates whether there are more records after the current page set. public Boolean hasNext { get { return con.getHasNext(); } set; } // indicates whether there are more records before the current page set. public Boolean hasPrevious { get { return con.getHasPrevious(); } set; } // returns the page number of the current page set public Integer pageNumber { get { return con.getPageNumber(); } set; } // returns the first page of records public void first() { con.first(); } // returns the last page of records public void last() { con.last(); } // returns the previous page of records public void previous() { con.previous(); } // returns the next page of records public void next() { con.next(); } // returns the PageReference of the original page, if known, or the home page. public void cancel() { con.cancel(); } public void ProcessSelected(){ selectedAccountsToUpdate = new List<Case>(); for(CategoryWrapper wrapobj:categories ) { if(wrapobj.checked==true) setSelectedAcc.add(wrapobj.cat); } selectedAccountsToUpdate.addall(setSelectedAcc); selectedAccounts.addall(selectedAccountsToUpdate); System.debug('@@@@@@'+selectedAccounts); update selectedAccountsToUpdate; wrapaccountList=null; } public class CategoryWrapper { public Boolean checked{ get; set; } public Case cat { get; set;} public CategoryWrapper(){ cat = new Case(); checked = false; } public CategoryWrapper(Case c){ cat = c; checked = false; } } }Regards.
Don't forget to mark your thread as 'SOLVED' with the answer that best helps you.
Zuinglio Lopes Ribeiro Júnior,
i will explain correct problem ,
we are in first page i selected two record after that I clicked 'show Selected accounts ' that time selected records are appear in below pageblock.which is good.
