Hi stoyo,

I am using new version of minfussion and working with diagram. I can insert three type of diagram node which are media Chanel , clock and shape node control. For media channel, I have written class which is inherit from "shapenode" class and for clock which is belongs to "ControlNode" and third is diagram shape node. My requirement is zindex of shape node is always less than of zindex media channel and clock control, and media Chanel and clock control maintain zindex automatically as they inserted. I have done it in it's previous version, using this code, when insert shape node in diagram. code is here:-

diagramNode.ZIndex -= diagram.Nodes.Where(Function(x) TypeOf x Is MultimediaControl OrElse TypeOf x Is ControlNode).Count and i am saving all node database by making xml string in which Zindex of node is stored respectively.

this code is automatically maintain the zindex of all node, which is available in diagram because of zindex is unique. But I have analysed it in new version,if media chanel and clock placed at the diagram before shape node and insert shape node in diagram, then shape node is come above of all media chanel and clock control.

How to overcome from this issue, please suggest me something. so that i can meet my requirement.

Thanks in advance

Hi Stoyo,

Thanks for replying back. Your solution is working. Shape node is always behind the media Chanel or clock control. But in my project, There are 4 buttons named "Bring To Front", "Bring Forward" , "Send Backward" and "Send To Back". It's means media Chanel go back to or come front of another media Chanel or clock control and same condition applied for clock control. I maintained through Zindex of Node. So i am using new version now, in new version, layer concept is there. I want to maintain this condition in new version i.e media Chanel go back to or come front of another media Chanel or clock control but not behind the shape node.

How can i do it ? Please suggest me something....

Thanks in advance

Hi Stoyo,

Thanks to reply back. Yes your solution working fine. I am creating New bound with 2 layer. code is here:-

BGBounds = New Rect(0, 0, 1024, 768)
BGNode = diagram.Factory.CreateContainerNode(BGBounds)
Dim lc As New MindFusion.Diagramming.Layer
Dim lc1 As New MindFusion.Diagramming.Layer
diagram.Layer.Add(lc)
diagram.Layer.Add(lc1)

and whenever i place any node in diagram and set LayerIndex of node. For media Chanel and clock , set LayerIndex to 1 and Shape Node is 0. shape node is always behind the media and clock chenel. But i can cut, copy and paste node by code. here is code


For Lop = 0 To CopyNodeList.Count - 1
Dim NewNode As Object
NewNode = CloneControl(CopyNodeList.Item(Lop))
If NewNode IsNot Nothing Then
With NewNode

If X >= 0 Or Y >= 0 Then
Dim r As Rect
r = NewNode.GetBounds
r.X = X
r.Y = Y
NewNode.SetBounds(r, True)

Dim node As ShapeNode
Select Case NewNode.GetType.ToString
Case ShapeTypeName
.Id = "Shape#" & Trim(Str(NodeCountID))
.Name = GetNextValidNodeName("Shape ")
node = CopyNodeList.Item(Lop)
Dim MS As ImageSource = node.Image
.Image = MS

Case ControlTypeName
Dim SplitSt() As String
SplitSt = Split(.ID, "#")
If UBound(SplitSt) < 2 Then ReDim Preserve SplitSt(2)
.Id = "DateTime#" & Trim(Str(NodeCountID)) & "#" & SplitSt(2)
.Name = GetNextValidNodeName("Date & Time ")
'Tag Pos 2
SplitSt = Split(.ID, "#")
Select Case Val(SplitSt(2))
Case 0
Dim CTL As New CTLDigitalClock
.Control = CTL
Case 1
Dim CTL As New CTLAnalogClock
.Control = CTL
End Select

Case AppName & ".MultimediaControl"
.Id = "Media#" & Trim(Str(NodeCountID))
.Name = GetNextValidNodeName("Media ")

Select Case .SubType
Case "Media"
.Image = New BitmapImage(New Uri("/local;component/Content/Images/Office/multimedia.png", UriKind.RelativeOrAbsolute))
End Select
End Select


End With

If Not (TypeOf NewNode Is MultimediaControl OrElse TypeOf NewNode Is ControlNode OrElse TypeOf NewNode Is ControlNodeEx) Then
NewNode.LayerIndex = 0
Else
NewNode.LayerIndex = 1
End If

BGNode.Children.Add(NewNode)
diagram.Nodes.Add(NewNode)

Node:- CopyNodeList is the list which hold all copied node.
after paste node shape node come above of media chenel and clock. i have analyst i.e LayerIndex of Shape node is 0. what i can do? Please suggest me something ......

Thanks in advanced.

Hi syoyo,

Thanks for reply. I have done same task but it didn't worked. Please suggest me another solution.

Thanks in advanced.
