    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim cell As UltraTreeNodeCell = Me.ultraTree1.ActiveNode.Cells("CompanyName")

        '	If the cell's node is selected, use the appearance
        '	to make the cell more visually apparent.
        If cell.Node.Selected = False Then
            cell.Appearance.BackColor = Color.Red
            cell.Appearance.ForeColor = Color.White
        End If

        '	Assign an EditorWithText with a custom EmbeddableEditorOwnerBase
        '	derived implementation.
        cell.Editor = New EditorWithText(New CustomOwner(cell))

        '	Output the cell's displayed value to the debug window
        If cell.Column.NullText.Length = 0 AndAlso Not cell.Value Is Nothing Then
