See Also  Example
Infragistics.Win.UltraWinTree Namespace > UltraTree Class : BorderStyle Property

Determines whether the tree has a border and if so, how it displays.

Syntax

Visual Basic (Declaration) 
Public Property BorderStyle As UIElementBorderStyle

public UIElementBorderStyle BorderStyle {get; set;}

Example

The following sample code initializes various properties on an UltraWinTree control and illustrates how to populate the tree.
