As suggested in this help article
if you want to achieve smooth items sliding you should ensure that the size of the RadRotator's view port can fit the number of items you want to display at a time. If the properties Width
are set according to the instructions in the help article and the problem persists, most probably there are global CSS styles that are modifying the size of the rotator items or adding padding/margin thus breaking the correct behavior of the rotator. Please check if there are such styles and try removing them from your page.
If you want to display only one frame at a time the value of Width
should be equal to ItemWidth
should be equal to ItemHeight
The online demo Slider / Custom Scrollbar
will be useful for implementing the behavior from the page you linked.
You can handle the server-side event OnItemClick
of RadRotator to maintain the control's current index. Check the linked article for an example.
All the best,
