NodeDoubleClickAction Enumeration

Determines what happens when double-clicking on a node.
Syntax
'Declaration
 
Public Enum NodeDoubleClickAction 
   Inherits System.Enum
public enum NodeDoubleClickAction : System.Enum
Members
MemberDescription
DefaultUse Default. Walks up the parent chain of the Override.
NoneNone.
ToggleExpansionToggle Expansion.
ToggleExpansionWhenExpansionIndicatorVisibleToggle Expansion only when the node has an Expansion Indicator. This is useful for loading child nodes on demand.
Example
The following sample code illustrates how to set some node behavior options.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTree

Private Sub button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button7.Click

    ' Note: the Override objects are exposed as properties off
    ' the tree, the node and the nodes collection as well as
    ' items in the NodeLevelOverrides collection. This allows
    ' default settings to be specified for the tree, a node, 
    ' a node's children or for a level in the tree.

    ' set the default for all nodes.
