Infragistics2.Win.UltraWinTree.v8.1
ImagePadding Property
See Also  Example
Infragistics.Win.UltraWinTree Namespace > UltraTree Class : ImagePadding Property

Gets/sets the ImagePadding which is the space before images.

Syntax

Visual Basic (Declaration) 
Public Property ImagePadding As Integer
C# 
public int ImagePadding {get; set;}

Remarks

Determines the amount of blank space before each image. This is used to seperate images in the UltraTreeNode.LeftImages and UltraTreeNode.RightImages collections.

Example

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