I use Tree Importer to draw diagram from database and then I use a NTextShape for writing header title in my document. But the diagram covers my TextShape because it's in front of it. How can I move down my Tree so I can see the title into TextShape?

Hi,
Create and insert the text shape first and then import the diagram from the database. If the shapes still overlap then you can use one of the tree layouts to layout them, for example:
NLayeredTreeLayout layout = new NLayeredTreeLayout();
layout.VertexSpacing = 50;
layout.LayerSpacing = 50;
layout.Layout(document.ActiveLayer.Children(null), new NDrawingLayoutContext(document));

I've tried with NTipOverTreeTayout but i've still the same problem.
Probably there is an error in my code:
Private Sub InitDocument()
m_Dict = New Dictionary(Of NTableShape, clsDipendente)()

NDrawingDocument1.Style.TextStyle.TextFormat = TextFormat.XML

NDrawingDocument1.ShadowsZOrder = ShadowsZOrder.BehindDocument
NDrawingDocument1.ActiveLayer.Name = "Org"
' Dim text As NTextShape = New NTextShape("Company Structure", New NRectangleF(NDrawingDocument1.Bounds.Width + 5, NDrawingDocument1.Bounds.Y + 5, 200, 50))
Dim text As NTextShape
If p_Funzioni Then
text = New NTextShape("ORGANIGRAMMA FUNZIONALE REPARTO " & p_Titolo, New NRectangleF(NDrawingDocument1.Width * 2 / 3, 0, NDrawingDocument1.Width / 3, 100))
Else
text = New NTextShape("ORGANIGRAMMA REPARTO " & p_Titolo, New NRectangleF(NDrawingDocument1.Width * 2 / 3, 0, NDrawingDocument1.Width / 3, 100))
End If
text.Style.TextStyle = New NTextStyle(New Font("Times New Roman", 20, FontStyle.Bold))
text.Style.TextStyle.StringFormatStyle.HorzAlign = HorzAlign.Right
NDrawingDocument1.ActiveLayer.AddChild(text)
Dim treeLayer As New NLayer()
treeLayer.Name = "Organigramma"
NDrawingDocument1.Layers.AddChild(treeLayer)
NDrawingDocument1.ActiveLayerUniqueId = treeLayer.UniqueId
' ''Dim layout As NLayeredTreeLayout = New NLayeredTreeLayout()

End Sub

By default layouts arrange the drawing relatively to the upper-left corner of the drawing.Bounds. That is why the tree/graph data importers arrange the drawing at the 0,0 origin. - provided that you have not modified the drawing.Bounds . The easiest way to place a header on top of your arranged drawing:
1. Import the data first,
2. Add the header text shape on top of the drawing.Bounds rectangle (for example with bounds new NRectangleF(0, -20, 1000, 20)).
3. Call the document.SizeToContent() method.
