Hi Sutthipong,
Thank you for contacting Syncfusion Support,
We have analyzed your screenshot (“This command is not supported in IE8”) and tried to reproduce the reported issue. We have created a sample and this issue occurs in IE8 “SCRIPT5009: 'jQuery' is undefined” which leads to no control created in the webpage. This issue might be occurred if you have referred jQuery 2.x or higher version in your application since jQuery 1.7.1 to 1.12.4 only supported in Internet Explorer 6, 7, or 8.
If still you are facing the issue, please revert the sample to replicate the issue at our end. This will be helpful for us to analyze and provide an exact solution at the earliest.
Regards,
Sureshkumar P
