ChartWebControl accesses null pointer at load time

[Adam Bruss]

Hello and thanks for syncfusion.

I have an asp.net website with a ChartWebControl on it. A null pointer is accessed in the syncfusion chart code at page load time. I've tried setting a datasource and a series to the chart, but still get a null pointer access at page load time.

Here's the error message.

"Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

What do I have to do to get the chart to load?

Thanks!

Hi Adam,

Could you please let us know whether you are using AJAX ScripManager or not? If not, we suggest you to use ScripManager in the web form to avoid the “Object reference not set to an instance of an object” error during in run-time.
