    Hello Rajendar,

    What you can try is to add an additional property of type boolean in your object. After building your source, you can traverse it and set the "duplicate" flag with your own code. In this way, you will have an additional column in the grid which will hold an information whether the row is duplicated. Then you can benefit from our RowStyleSelector. You can use it in order to style the duplicate rows. It will be something similar to this:

    public override Style SelectStyle(object item, DependencyObject container)
               if (item is MyObject)
                   MyObject myObject = item as MyObject;
                   if (myObject.IsDuplicate)
                       return DuplicateStyle;

    I hope this will work for you.
