How to manage the uitableviewcell after being scrolled?

Question

Hi all.
I manipulated the cell of the table view to be a custom one, which will be expanded(from height=50 to height=100) on selection and will be srinked to original(from height=100 to height=50) on second click or deselction. Now my problem is that i am selecting a row and without deselecting it or without clicking it for second time if i am scrolling the table ,the cell should reload to the original(height=50) srinked one. Here the view is reloading but the height for that row is not srinking(still height for that row remains to be 100). Can anyone have tried like this? Plz help me to sort out the problem.
Tanks in advance.
Satya.

Well sorry for late responsse, here is the code:_
@interface HomeControl : UIViewController<UIScrollViewDelegate,UITableViewDelegate,UITableViewDataSource >
          IBOutlet UITableView *newsTable;
          NSArray *dataArray;
          NSMutableArray *selectedRowArray,*clickedCountArray;
          CGRect frame;
@property (nonatomic,retain) UITableView *newsTable;
@property (nonatomic,retain) NSArray *dataArray;
@property (nonatomic,retain) NSMutableArray *selectedRowArray,*clickedCountArray;
@end
@implementation HomeControl
@synthesize newsTable,dataArray,selectedRowArray,clickedCountArray;
- (void)viewDidLoad
          //table view section
                    NSDictionary *row1=[[NSDictionary alloc] initWithObjectsAndKeys:@"News",@"newsCatagory",@"News Title",@"newsTitle",nil],*row2=[[NSDictionary alloc] initWithObjectsAndKeys:@"News'it",@"newsCatagory",@"News Title",@"newsTitle",nil],*row3=[[NSDictionary alloc] initWithObjectsAndKeys:@"News",@"newsCatagory",@"News Title",@"newsTitle",nil],*row4=[[NSDictionary alloc] initWithObjectsAndKeys:@"Fashion",@"newsCatagory",@"Good Deal Title",@"newsTitle",nil],*row5=[[NSDictionary alloc] initWithObjectsAndKeys:@"News",@"newsCatagory",@"News Title",@"newsTitle",nil];
                    NSArray *a=[[NSArray alloc] initWithObjects:row1,row2,row3,row4,row5,nil];
                    self.dataArray=a;
                    [row1 release];[row2 release];[row3 release];[row4 release];[row5 release];[a release];
                    selectedRowArray=[[NSMutableArray alloc] initWithCapacity:dataArray.count];
                    clickedCountArray=[[NSMutableArray alloc] initWithCapacity:dataArray.count];
                    for(int i=0; i<[dataArray count]; i++)
                              [selectedRowArray addObject:[NSNumber numberWithInt:0]];
                              [clickedCountArray addObject:[NSNumber numberWithInt:0]];
- (void)viewDidUnload
          // Release any retained subviews of the main view.
          // e.g. self.myOutlet = nil;
          self.newsTable=nil; self.selectedRowArray=nil;          self.clickedCountArray=nil;
          self.dataArray=nil;
          [super viewDidUnload];
- (void)dealloc
          [newsTable release]; [selectedRowArray release]; [clickedCountArray release];
          [dataArray release];
    [super dealloc];
