I'm trying to implement pie chart from demo link: http://demos.telerik.com/aspnet-mvc/razor/chart/piechart
I'm using .NET 4.5/MVC4/ with Telerik version (TelerikControlPanel_2012_3_1214 and Telerik_Extensions_for_ASPNET_MVC_2012_3_1018_Commercial)
Two questions:
1) I'm getting below error:
Error! Data binding failed. Unexpected server response - see console
How can I troubleshoot this error?where is telerik console?
2) Can I implement server side binding with pie chart. Any samples would be great!
Here is my code:
Thank you!!!

Hello. Anyone from Telerik support monitoring this forum?

Hi,

The error should be visible in the browser console. The console is accessible in a manner specific for each browser:
- Internet Explorer - Open the developer tools (F12) and choose the Script tab. The console is visible on the right.
- Firefox - Install Firebug and enable the Console tab.
- Chrome - Open the JavaScript console (Ctrl + Shift + J).
- Safari - Enable the Develop menu from the Preferences / Advanced dialog. Open the error console from the Develop menu.
A pie chart demo with server binding is available here: http://demos.kendoui.com/dataviz/pie-charts/remote-data.html
The full code for the MVC version is available in the offline demos.
Response time for the forums is around 72 hours. Please, use the support ticketing system if you require response within 24 hours.
