Hi rajesh gupta,
We strongly recommend getting to know quite well with the API documentation especially for components such as the jqxGrid.
One of the parameters of the export method is the URL for the export server. By default is hosted by jQWidgets.
When you buy the license of our products you will have access to the export file and you can host on you own server and this will eliminate the message that you get.
Again I strongly recommend to take a look at the exportdata
method and its parameters in the API docs here- https://www.jqwidgets.com/jquery-widgets-documentation/documentation/jqxgrid/jquery-grid-api.htm
Please, do not hesitate to contact us if you have any additional questions.
Best Regards,
Yavor Dashev
