Hi Manas Rastogi,

Well, updating the values in this manner could introduce some serious problems. If you are dealing with many rows some of them might not be available bacause of the virualization techniques that RadGridView uses - as a result some rows will not be updated.

A better approach is to update the actual data that the grid is bound to. If your grid is boud to customer objects and the column that you would like to update displays the age of all customers just update the property Age of all your objects (your data items should implement INotifyCollectionChanged interface).

public void UpdateAge()
{
   foreach(Customer customer in this.myGrid.Items)
   {
       customer.Age++;
   }
}

I have also attached a sample project that demonstrates the approach.

Kind regards,
