I am using Diagram control as shown below
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
        <ndiag:DiagramView runat="server" ID="diagramView" ClientSideMode="Canvas" Width="1900px" Height="1050px" NodeDoubleClickedScript="onNodeDoubleClicked" Behavior="DoNothing">
        </ndiag:DiagramView>
    </ContentTemplate>
</asp:UpdatePanel>

We have collection of nodes in the Diagram
Based on some conditions we update the text of the node in the diagram in the server side as

For Each node As DiagramNode In diagramView.Diagram.Nodes
              If node.Tag.ToString.ToUpper = "TEST" Then
CType(node, ShapeNode).Text = myValue
  End If
Next

Now I need to update this node text value in client side which is received by web service. There is timer function
function myTimer() {

        $.ajax({

            url: webServiceURL,
            type: "POST",
            dataType: "xml",
            data: soapRequest,
            processData: false,
            contentType: "text/xml; charset=\"utf-8\"",
            success: OnSuccess,
            error: OnError
        });
    }

function OnSuccess(data, status, req) {
        if (status == "success") {
           //Here I need to put the code to update the node text.
        }
    }

Diagram object methods like Diagram.nodes not available in client side. Could you please provide sample code to achieve this?

Hi,
When I try to get nodes using Digram.GetNodes() like below
function OnSuccess(data, status, req) {
if (status == "success")
{
var Diagram = document.getElementById('<%= diagramView.ClientID%>');
var obj = Diagram.getNodes();
}
}
It did not work and I get error as
TypeError: Diagram.getNodes is not a function
Is there mistake in my code?

Also
for (var node of diagram.getNodes())

doesn't compile.

Regards

Hi,
I tried with both methods as
MindFusion.Diagramming.Diagram.find(id) or $find(id) but still no luck. It is null somehow.

function OnSuccess(data, status, req) {
if (status == "success")
{
var Diagram = MindFusion.Diagramming.Diagram.find('diagramView');
var diagram1 = $find('diagramView');
var obj = Diagram.getNodes();
}
}

This gives me following errors as
Uncaught Sys.ArgumentException: Sys.ArgumentException: MindFusion.Diagramming.Diagram does not derive from Sys.Component.
Parameter name: type

and

Uncaught TypeError: Cannot read property 'getNodes' of null
at Object.OnSuccess [as success]

Hi Slavcho,
Sorry for late reply.
The issue was that, I was using control in .ascx page. It works OK in .aspx page. Thanks a lot for your help.
