ItemHeight Property

Gets/sets the height of an UltraTreeNode.
Syntax
'Declaration
 
Public Property ItemHeight As Integer
public int ItemHeight {get; set;}
Remarks

To reset the ItemHeight to the default value, call the ResetItemHeight method.

To ensure a clean display, the actual height of the node may vary from the specified value by up to one pixel.

Example
The following sample code illustrates how to specify the height of nodes.

Private Sub button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button6.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.ItemHeight = 20

    ' 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).ItemHeight = 30

    ' Set the default for nodes at the root level. 
    ' This overrides the default settings above.
    Me.ultraTree1.Nodes.Override.ItemHeight = 15

    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")

    ' Set the property for that specific node only.
    ' This overrides any default settings above.
    node.Override.ItemHeight = 40

    ' Set the property for that specific node's child nodes
    node.Nodes.Override.ItemHeight = 35

End Sub
private void button6_Click(object sender, System.EventArgs e)
{

	// 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

	this.ultraTree1.Override.ItemHeight = 20;
		
	// Set the default for nodes that are at level 2

	// This overrides the default setting above.
	this.ultraTree1.NodeLevelOverrides[2].ItemHeight = 30;

	// Set the default for nodes at the root level. 
	// This overrides the default settings above.
	this.ultraTree1.Nodes.Override.ItemHeight = 15;

	// 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

	UltraTreeNode node = this.ultraTree1.GetNodeByKey("child node 1");

	// Set the property for that specific node only.
	// This overrides any default settings above.
	node.Override.ItemHeight = 40;

	// Set the property for that specific node's child nodes
	node.Nodes.Override.ItemHeight = 35;
