Hi Sitharam,
Please ignore the previous update.
We can acheive your requirements by setting the background property of the grid control.
Code snippet [C#]:
this.grid.Model.TableStyle.Background = Brushes.Red;
this.grid.Model.HeaderStyle.Background = Brushes.Red;
We have prepared a sample based on this and you can find the sample under the following location.
