Hello josephine shirley,
Thank you for writing.
The
SmallImageList has no concrete functionality in the context of the RadToolStrip control. It exists, because RadToolStrips inherits from RadControl. However, you can always implement dynamically image changing through code at run-time.
A bit off topic, I would like to remind you that your subscription package has expired, which means that you are not etitled to support services. I would highly recommend upgrading your license to the latest version in order to continue getting product updates and uninterrupted support services. Please, contact sales@telerik.com or visit your account for your upgrading options.
Greetings,
Martin Vasilev
