How to view and edit visio files in

I have a .net web application where I need to show the visio file and view and edit the files online, How can I use the aspose dll to view the file and edit online?

where can I see the code for view and edit the visio files in web page?

Hi Jiju,

Thank you for contacting support. Please note, Aspose.Diagram is a class library for working with Microsoft Visio files. It allows developers to work with VSD, VSDX, VSS, VST, VSX, VTX, VDW and VDX files on C#, VB.NET, ASP.NET web applications, web services, Mono and Windows applications. Please refer to the help topics there:

So in short, it allows to manage Visio diagrams in background. However, it does not provide UI document editor tool or control. Our GroupDocs brand may help you in this regard. Please checkout GroupDocs at

in the below url

it is mentioned that "The contents of the diagram can be manipulated through the Aspose.Diagram API. After making the required changes to the Visio file, the file can then be written to disk in VDX, VSX or VTX formats"

How is it possible without a UI editor?

Hi Jiju,

Thank you for the inquiry. Please note, it is a class library project and we provide Aspose.Diagram libraries. Users add reference of these libraries in their .NET projects and finally can manipulate diagram elements programmatically through its rich API support. Furthermore, you can download and use Aspose Examples Dashboard app to quickly learn how to use Aspose products.

Please refer to the help topic, where we’re generating an empty diagram and saving it in VDX format.

Please also refer to the appropriate download page and blog post:

I have looked at GroupDocs component and seeking for a Visio Editor (like the one you are using in your demo but I couldn’t find anything like that. Do you have any suggestion, Imran?
