Hi Hong,
Thank you for contacting Telerik support.
In order to display the image, you need to set the
DropDownStyle property to
DropDownList. Please refer to the attached sample demo demonstrating how you can achieve it.
If I did not understand correctly your case, please describe with more details what you want to achieve.
Let me know if I can assist you further.
Regards,
