I am evaluating the Nevron Chart for Sharepoint 2009 Vol 2 version and I am impressed and excited at what I have been able to achieve through the web part. After running the 'Run Chart Designer' and connecting to my datasource, I can create the charts I need and preview them. However the problem I have is when I am finished and want to 'publish/display' the chart on my Sharepoint site (by clicking the apply or ok button) the Nevron Webpart display a box with an error message in it that says;
" The following error occurred while updating the chart: ConnectionString cannot be an empty string."
Can someone help me with this?
Hello Peter,
Thank you for your evaluation and your interest in Nevron Chart for SharePoint.
Can you check if you have administrator rights on the SharePoint server? Also, did you managed to run the Chart Samples which are distributed with the Chart for SharePoint installation package?
When you click on the “Apply” button from the designer, do you have any specific error message in the bottom of the page? Which browsers are you working with?
We will do our best to assist you.
Best Regards,Nevron Support Team
