Hi Rajendran,

below some detail that you want:

1) Syncfusion version details: 
2) details of script error if any occurred in the browser console: in my browser I don't have grid but when I debug my code witch breakpoint in EJSGRID bloc, the cursus break this bloc and I have this error message 
 
you can that when my condition is ok (when moData != null) normally the EJSGRID should display data but it's not the case. 
normally without Data the grid should display the scheme.
N.B: in the other case the same grid display the local data.

3) External source data




my grid is in the condition  as you can see

Hi Roland, 

Thanks for the details. 

We request you to share the details regarding the type of data you are getting from the oResponse.Response(like whether it’s a List of objects or IEnumerable etc.). And also, as Grid is not rendered in the browser(not even the schema), we suspect that there may be some script errors in the browser’s console window. So please share the details of script error if you face any script errors in browser’s console window. 

And also we would like to inform you that, we have support “Custom way of binding” data to Grid, which is a recommended way for binding data from external service links to Grid. So we suggest you to try binding the data to Grid through CustomAdaptor and if you facing any difficulties, then kindly get back to us. 

Regards, 
Renjith Singh Rajendran.
