  • With RadTreeView you can customize the look and feel of each single TreeNode.

    The TreeNodes expose the following properties that can be used to apply certain CSS classes to the nodes:

    CssClass
    DisabledCssClass
    HoveredCssClass
    SelectedCssClass

    Each of the above properties determines the CSS class to be applied to the TreeNode when it is in the respective mode (normal, disabled, hovered and selected).

    This example shows how to use the CssClass properties of the nodes to make them look unique.
