Hello Shailesh,
Please, check your references.
Are there all needed files and especially the “jqx.base.css” file?
You could try to add the mentioned one and the “jqx-all.js” file for testing purposes.
It will be better if you could provide us with whole source code – one simple jseditor or jsfiddle example will be better.
Also, I would like to suggest you try to use our jqxPopover with the jqxGrid.
Please, take a look at our page with integration with the Bootstrap.
Best Regards,
