Editing with ImageMap, applet and SL based tool (Read 3721 times)

	Hi. We are investigating the possibility to have a diagram drawing tool that adapts to the clients capabilities. * Diagrams are persisted on the server side * If the client PC has the Java (or Silverlight) runtime installed, the diagram is opened in a Java applet (or Silverlight) version of our drawing tool. * Otherwise the diagram is opened in an ImageMap-based version of our drawing tool * A diagram that is saved in either version of the tool can be opened and edited with the other version of the tool. Is this scenario technically feasible with the MindFusion components? What are the limitations? Best regards, Jonas

	Hi, There is no built-in detection of the available runtimes coming with the control. You might detect the runtime on some kind of welcome page and then redirect to a page that shows DiagramView in the respective mode. The bigger problem is that the client-side scripting APIs are very different at this time, so if you need to do provide more than simple diagram editing, you might have to implement several sets of JS scripts. I hope that helps, Stoyan

	Thanks Stoyo. How about the XML-document format used by the ImageMap, Java applet and SIlverlight components? Is it possible to save a diagram with DiagramLite SaveToXml, and later open and edit the diagram using NetDiagram LoadFromXml? Best regards, Jonas

	Hi Jonas, Yes, it's possible. The server .NET component sends data to the client side through XML in all modes. Only if you create your own Silverlight control to host the Silverlight Diagram, make sure you don't specify WpfPoint as MeasureUnit - it's not supported in the other modes yet. I hope that helps, Stoyan

	Thanks Stoyo, that sounds promising. There seem to be differences in the version of the XML -format used by the NetDiagram trial version and the DiagramLite trial versions; I found sample XML files with version=11, version=12 and version=13. How can we make sure that we use versions of NetDiagram and DiagramLite that are compatible on the XML-version level? Best regards, Jonas

	You will get version 11 only if using the XmlWriter class, which is obsolete and shouldn't be available in the API anymore. Are you using an older version of NetDiagram by any chance? Now you should use the Diagram.SaveToXml method for XML serialization. The new in format 13 is support for a more compact xml representation where properties with their default values are not saved. You can override this by calling SaveToXml overload that takes a boolean argument. Stoyan
