Hi Stefan,

 Thanks for helping me out. I went through the Online Documentation for creating a theme Pack and did the 5 steps explained there. But i get err on the 2nd step where we need to inherit the ResourceSet. The err  says "DataPresenter.Locator" doesn't exist  . I have added all references as mentioned there.I have given the snippet for reference.

public class DataPresenter : DataPresenterResourceSet<DataPresenter.Locator>
        {
            private static DataPresenter g_Instance;

            public static DataPresenter Instance
            {
                get
                {
                    if (g_Instance == null)
                        g_Instance = new DataPresenter();
                    return g_Instance;
                }
            }
        }
  public class Locator : ResourceSetLocator
  {
      public override Assembly Assembly { get { return this.GetType().Assembly; } }
      public override string Theme { get { return "OrangePeel"; } }
      public override string Grouping { get { return DataPresenterGeneric.Instance.Grouping; } }
      public override string ResourcePath { get { return @"ResourceSets\DataPresenter\DataPresenter.xaml"; } }
  }
