Hi,

Since the ASP.NET process cannot access the printer, you cannot print on the server side. You could either call print() on the client side in JavaApplet mode, or use PdfExporter to create a PDF file and let the user print it. Another option is to run a Windows process that polls a directory for new diagram or PDF files and prints them.

I hope that helps,

Hello, I was reviewing this thread thinking too that there was a diagramView.print() function for NetDiagram. Since October last year has any changes been made to allow printing for NetDiagram? Thanks

Yes, where ever I try to use the method, I receive an error that it does not exist. I tried it in the javascript too:

protected void btnPrint_Click(object sender, EventArgs e)
       {  MindFusion.Diagramming.WebForms.DiagramView.print(); //errors that there is no definition for print()
       }

and I tried

function printDiagram() {
           alert("gothere");
           var dvApplet = document.getElementById("diagramView");
           var dv = dvApplet.getDiagram();
           dv.print(); }
//errors object does not support property or method

I looked in the documentation and believe I am using it correctly. Any thoughts?

Works! Thanks!

The control does not scale automatically the diagram to fit the page. Are you printing to a real printer or some kind of a pdf printer?

Are you changing anything in DiagramView.PrintOptions?

I've added this to the OrgBrowser sample and printed a large tree, the result seems ok:

<button onclick="onPrint();">Print</button>
<script language="javascript" type="text/javascript">
function onPrint()
{
	var fcApplet = <%= fc.AppletElement %>;
	fcApplet.getDiagramView().print();
}
</script>
 

Could you try this with your printer? You might check if there aren't some strange margin and scale values set in the printer properties window as defaults.

Hello,

Yeah my diagram was not fitting within the page like the example you provided works because my units are in pixels.

In OrgBrowser sample in the code behind I added:

d.MeasureUnit = GraphicsUnit.Pixel;

and this replicated the problem I am having printing.

using zoomToFit(); zooms the diagram in the applet in the browser, not the diagram the is printed.

I have messed around with some other setting and have not come up with a solution. I cannot set the units to 'units' instead of pixels right before I print because that would make my images and text positioning and proportions off.

Any ideas?
