public enum SelectType : System.Enum
Members
MemberDescription
DefaultUse Default. The setting of the object's parent will be used.
ExtendedExtended Select. Multiple objects may be selected at once. Selecting and Dragging will select a range of nodes.
ExtendedAutoDragExtendedAutoDrag Select. Multiple objects may be selected at once. Selecting and then dragging will fire the SelectionDragStart event to allow the beginning of a DragDrop operation.
NoneNo Select. Nodes cannot be selected.
SingleSingle Select. Only one object may be selected at any time. Selecting and Dragging will select the node under the mouse pointer.
SingleAutoDragSingleAutoDrag Select. Only one object may be selected at any time. Selecting and then dragging will fire the SelectionDragStart event to allow the beginning of a DragDrop operation.
Example
The following sample code illustrates how to specify the selection strategy for nodes.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTree

Private Sub button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button9.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.

    ' Use the tree's Override property to
    ' set the default for all nodes.
    Me.ultraTree1.Override.SelectionType = SelectType.Extended

    ' Set the default for nodes that are at level 2 
    ' (i.e. grandchild nodes of root modes).
    ' This overrides the default setting above.
    Me.ultraTree1.NodeLevelOverrides(2).SelectionType = SelectType.None

    ' Set the default for nodes at the root level. 
    ' This overrides the default settings above.
    Me.ultraTree1.Nodes.Override.SelectionType = SelectType.Single

    Dim node As UltraTreeNode

    ' Get a specific node by its key value. 
    ' Note: this will return the node that has that key
    ' from anywhere in the tree structure since keys are
    ' unique across the entire tree.
    node = Me.ultraTree1.GetNodeByKey("child node 1")

    ' Note: Setting this property for a specific node is
    ' ignored since selection (e.g single/multi) is governed
    ' by the setting on the nodes collection that the node 
    ' is contained in. Therefore, the following commented
    ' out line would have no effect.
    'node.Override.SelectionType = SelectType.SingleAutoDrag

    ' Set the property for that specific node's child nodes
    node.Nodes.Override.SelectionType = SelectType.ExtendedAutoDrag
