Hi PLST,
Thanks of the interest in Syncfusion products.
You can change the non-client area of the gird using grid backcolor property. Please refer the following code snippet that
shows how you can change the non-client area of the grid.
this.gridControl1.Properties.BackgroundColor = Color.Yellow;
Please refer the sample in the below link that illustrates the above.
