Hi Anderson,
We deeply regret for the inconvenience caused.
At present the Multiline support is provided for MultiColumnTreeview only. We have notified our documentation team to move the Multiline support document under MultiColumnTreeview control.
The feature 'Ability to display multiline Text in TreeNodeAdv' is not available with our current library. We have already logged a feature request for this. We will implement this feature in our forthcoming new version releases or service pack releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We will get back to you once the feature is implemented.
As a workaround you can use TextBox as CustomControl in TreeNodeAdv and when TreeViewAdv width is changed you can set Multiline property of TextBox to true as follows.
Me.treeViewAdv1.Width = 124
Me.textBox1.Multiline = True
Me.textBox1.BorderStyle = BorderStyle.None
Me.treeViewAdv1.Nodes(1).Text = ''
Me.treeViewAdv1.Nodes(1).CustomControl = Me.textBox1
Me.treeViewAdv1.Nodes(1).Height = 36
