# Creating Custom Hierarchy Icons

Learn how to customize hierarchy icons in Spread.NET with the GetImage and SetImage methods in the SpreadView class.

## Content



You can customize the icons used for expanding and collapsing the hierarchy in a hierarchical display by using the [GetImage](/spreadnet/api/latest/online-win/FarPoint.Win.Spread/FarPoint.Win.Spread.SpreadView.GetImage.html) and [SetImage](/spreadnet/api/latest/online-win/FarPoint.Win.Spread/FarPoint.Win.Spread.SpreadView.SetImage.html) methods in the [SpreadView](/spreadnet/api/latest/online-win/FarPoint.Win.Spread/FarPoint.Win.Spread.SpreadView.html) class, which is described in [Customizing the User Interface Images](/spreadnet/docs/latest/online-win/overview/spwin-devguide/spwin-setappearance/spwin-userimages).

An example of how the default hierarchy icons, a simple plus sign and minus sign, appear is shown here.
