ReserveImageSpace Property

Gets/sets whether or not to reserve space for an image for nodes that do not have an image.
Syntax
'Declaration
 
Public Property ReserveImageSpace As Infragistics.Win.DefaultableBoolean
public Infragistics.Win.DefaultableBoolean ReserveImageSpace {get; set;}
Remarks

When true, nodes will reserve a space for an image.

When false, nodes without an image will not leave a space.

Note: This applies only to the image of a node as part of an Appearance. It does not apply to LeftImages or RightImages.

Example
The following sample code illustrates how to specify the image size to use for node images.

Imports Infragistics.Win

Private Sub button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button5.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.

    ' Reserve space for images even if a node doesn't have one.
    Me.ultraTree1.Override.ReserveImageSpace = DefaultableBoolean.True

    ' Use the tree's Override property to
    ' set the default for all nodes.

    ' Set the default for nodes that are at level 2 
    ' (i.e. grandchild nodes of root modes).
    ' This overrides the default setting above.

    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.
