The SaveLoad sample project shows how to transfer the diagram to the server. On the server side add a reference to the common, diagramming, pdf and diagramming.export.pdf assemblies form this package:
https://www.mindfusion.eu/NetDiagramTrial.zip

Then following the SaveLoad approach, load the string submitted from the client side and export it -

var str = Page.Request.Form["serializedDiagram"];
if (str.Length > 0)
{
	var d = new Diagram();
	d.LoadFromString(str);
	new PdfExporter().Export(d, "test.pdf");
}
 

I hope that helps,

Hi,

You can do that by calling Diagram.CreateImage to get a System.Drawing.Image representing the diagram, and then call the Image.Save method. Image.Save supports BMP, PNG, JPG and GIF formats.

I hope that helps,

This is available only in the diagramming.dll on the server side.

Here is an example that exports to PDF and PNG:

Hi,

There is no Jpeg or Bmp encoder available in the Silverlight API, so you can't export in these formats on the client side. There is only the diagram.SaveToPng method that lets you save to PNG files.

You might be able to export to Xaml using these tools, but we haven't tried them:

Hi,

This is shown in the SaveLoad example that comes with DiagramLite. There the diagram content is saved as a string in a HIDDEN html element and reloaded after postback, using the SaveToString and LoadFromString methods.

Of course you can do that without a postback, but by calling a service method that takes the SaveToString result as an argument, loads it inside a server-side Diagram and exports to image / PDF, and finally returns an URL to the exported file. Thus you could export the diagram and open the result without reloading the page.

Hi,

Could you email to support@mindfusion.eu your modified SaveLoad example? Have you defined the custom classes on the server side too?
