UltraTreeState Enumeration

Bit flags that describe the state of the control. For example,
Syntax
public enum UltraTreeState : System.Enum
Members
MemberDescription
ActiveCellThe UltraTree.ActiveCell property returns a non-null value.
ActiveCellIsInFirstLogicalColumnThe UltraTree.ActiveCell is in the first logical column of cells displayed by the UltraTree.ActiveNode.
ActiveCellIsInLastLogicalColumnThe UltraTree.ActiveCell is in the last logical column of cells displayed by the UltraTree.ActiveNode.
ActiveCellIsOnFirstLogicalRowThe UltraTree.ActiveCell is on the first logical row of cells displayed by the UltraTree.ActiveNode.
ActiveCellIsOnLastLogicalRowThe UltraTree.ActiveCell is on the last logical row of cells displayed by the UltraTree.ActiveNode.
ActiveNodeDisplaysCellsThe UltraTree.ActiveNode displays cells.
AllowCopyDetermines if the UltraTree.SelectedNodes can be copied to the clipboard.
AllowCutDetermines if the UltraTree.SelectedNodes can be cut to the clipboard.
AllowPasteDetermines if the nodes from the clipboard can be pasted into the UltraTree.ActiveNode's UltraTreeNode.Nodes collection.
CellInEditModeThe UltraTree.ActiveCell property returns a non-null value, and that cell is in edit mode.
FirstCellActiveThe UltraTree.ActiveCell property returns a non-null value, and that cell belongs to the first logical column displayed by the UltraTreeNode to which it belongs.
FirstNodeActiveThe first visible, enabled node displayed by the control is the UltraTree.ActiveNode.
HasNodeChangesPendingThe UltraTree.ActiveNode has pending changes to cell values that have not yet been committed.
InEditActive Node is in edit mode
IsCheckboxActive Node has a check box
IsOptionButtonActive Node's NodeStyle property is set to OptionButton
LastCellActiveThe UltraTree.ActiveCell property returns a non-null value, and that cell belongs to the last logical column displayed by the UltraTreeNode to which it belongs.
LastNodeActiveThe last visible, enabled node displayed by the control is the UltraTree.ActiveNode.
NextNodeDisplaysCellsThe next visible, enabled node relative to the UltraTree.ActiveNode displays cells.
NodeChildActive Node is a child Node
NodeExpandableActive Node is expandable
NodeExpandedActive Node is expanded
NodeFirstActive Node is first Node
NodeHasChildrenActive Node has Children
NodeLastActive Node is last Node
NodeNotExpandableActive Node is not expandable
NoFocusRectThe tree does not draw focus rectangles around the active node. This is probably because UltraTree.DrawsFocusRect is resolving to false.
PreviousNodeDisplaysCellsThe previous visible, enabled node relative to the UltraTree.ActiveNode displays cells.
TabKeyNavigatesToNextCellThe control's UltraTreeColumnSettings.TabNavigation property resolves to 'NextCell'
TabKeyNavigatesToNextControlThe control's UltraTreeColumnSettings.TabNavigation property resolves to 'NextControl'
Example
The following code illustrates how to add a custom key/action mappings to the tree that will toggle the expanded state of the active node when the user presses the ‘X’ key (unless the ‘alt’ key is also pressed).

Imports Infragistics.Win.UltraWinTree

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    Dim newAction As TreeKeyActionMapping

    ' Add 2 KeyActionMappings so that if the user presses
    ' the 'X' key (without also pressing the 'Alt' key)
    ' the active node will toggle its expanded state.

    ' The first mapping states that if the node is expandable
    ' and its not already expanded or in edit mode and the
    ' user presses the 'X' key then expand the node.
    newAction = New TreeKeyActionMapping( _
       Keys.X, _
       UltraTreeAction.ExpandNode, _
       UltraTreeState.InEdit Or UltraTreeState.NodeExpanded, _
       UltraTreeState.NodeExpandable, _
       Infragistics.Win.SpecialKeys.Alt, _
         0)

    Me.ultraTree1.KeyActionMappings.Add(newAction)

    ' The first mapping states that if the node is expanded
    ' and its not in edit mode and the user presses the 'X' 
    ' key then collapse the node.
    newAction = New TreeKeyActionMapping( _
       Keys.X, _
       UltraTreeAction.CollapseNode, _
       UltraTreeState.InEdit, _
       UltraTreeState.NodeExpanded, _
       Infragistics.Win.SpecialKeys.Alt, _
         0)

    Me.ultraTree1.KeyActionMappings.Add(newAction)

End Sub
