Hi Salem,
Thanks for the update.
In SfRotator control, SfRotatorItem's Image API can be used by assigning Image name as string values as shown below.
Code example:
SfRotatorItem item =new SfRotatorItem ();
item.Image="image.png";
Due to some stability issues, we had postponed the Custom View support for the Rotator control and it will be available in our upcoming 2016 Volume 2 release which is expected to be roll out by the mid of June, 2016. By using this custom View support, you can achieve your requirement of assigning the Images via URL. Please visit our website periodically for updates regarding releases.
Regards,
Paul Anderson
