Hi,

If you want to use the built-in TreeLayout class in this case, you will have to insert some invisible/temporary nodes, so that each leaf node has ancestors in every level above the leaf. Otherwise, I suppose t shouldn't be hard to arrange them yourself using a recursive function that tracks the current level.

after implementing the tree layout if i hide any of the tree node item (item.visible=false) then the chart looses its layout, links are broke n its mess.

After applying the treelayout. I am trying to push down the treenodes depending upon the level they belong to.
Node are pushed down perfectly but the links (Outgoing links from the pushed down node) are not pushed down, whereas (Incoming links are fine)
Please help........

for this i am using following code:

For Each item As DiagramNode In DG.Nodes
If TypeOf item Is TableNode Then
Dim n As TableNode = CType(item, TableNode)

Dim sizeF As RectangleF = item.Bounds
Dim x As Integer = sizeF.X
Dim y As Integer = sizeF.Y

Dim nDistanceToPush As Integer = y
'Some calculation to get how much to push down

y = nDistanceToPush
item.Move(x, y)
End If
Next

This solution is not going to solve my problem.
I found you have a containernode object.

Can i use the containernode object to group all nodes in one level.

I tried to do this but it had no effect/change in the output.

Is it possible to do in this way.
Please help.........

I used following code:

For nLevel As Integer = 1 To 7
Dim nodeContainer As ContainerNode = Nothing

For Each item As DiagramNode In DG.Nodes
If TypeOf item Is TableNode Then
Dim n As TableNode = CType(item, TableNode)
If n.Tag IsNot Nothing Then
Dim sTags() As String = n.Tag.ToString.Split(","c)
Dim sNodePos As String = sTags(0)
Dim sNodeLevel As String = sTags(1)

If sNodeLevel = nLevel Then
If nodeContainer Is Nothing Then
nodeContainer = New ContainerNode(DG)
End If
nodeContainer.Add(item)
End If
End If
End If
Next
If nodeContainer IsNot Nothing Then
nodeContainer.Foldable = True
nodeContainer.Folded = False
nodeContainer.Caption = "Level " & nLevel.ToString
nodeContainer.ShadowColor = drawing.Color.AliceBlue
nodeContainer.Visible = True
End If
Next

when diagram is exported in Visio its all color formatting is lost where as when exported to PDF its fine.

Please help

FlowChart.NET and NetDiagram provide the same layout classes. I will send you some code for the layout in a few days.

I am using following code to give different background to table captions

newTableNode.CaptionBackBrush = New MindFusion.Drawing.SolidBrush(Color.FromArgb(248, 113, 60))

but when exported to visio this color is lost i.e table caption has no background color.

Other then colors following formatting are lost:
1. Table border color and row line colors
2. Rounded rectangle node loose their rounded corners
