     We are using Telerik.web.chart charts and then convert them to images using chart.Save()

    I works fine when I use from web application, however if I invoke using windows service it throws an

    "Object reference not set to an instance of an object." error.

    Stack trace suggests   at Telerik.Web.UI.RadChart.Save(Stream stream, ImageFormat imageFormat). 

    however radchart object itself is not null but scriptmanager property is 

    Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request

    is there a way to generate images using telerik.web.UI outside http context or is it a completely different error. 

    cheers Vijay

    Hello Vijay,

    Can you please provide more details about the problem? As mentioned in my reply to the other message you have posted it seems to work correctly on our end.

    Best regards,
