C# .NET - Apply CSS for aspxTreelist

There are multiple options.

a) To style the ASPXTreeList controls, you need to use the inbuilt style properties.  And also I read that you need to set the  EnableDefaultAppearance  property to true for these styles to render. 

b) You can also set the CSSFilePath to a valid css, where you can choose to override the default styles.

c) Also note that, you can apply the style properties from code-behind as well. 
sampleASPxTreeList.Styles.Header.Assign(
new TreeListHeaderStyle () { 
BackColor = Color.LightBlue,
ForeColor = Color.Gray,
});

Hope this helps.
