    Hi Berrabah,

    In case you don't want to use a WebService, I would suggest utilizing the control's client-side method addRotatorItem, which will allow you to dynamically create and add  new items to the RadRotator's client-side item collection. The example below demonstrates how to utilize the mentioned method in order to add a new item at the end of the collection:
    var rotator = $find("<%=RadRotator1.ClientID %>");
    var radRotatorItemData = [];
    radRotatorItemData.Html = "<div>Item's content</div>";
    rotator.addRotatorItem(radRotatorItemData);

    You can use the RadRotator's client events OnClientItemShowing and OnClientItemShown to implement the loading of the new items at the desired moment during the sliding of the control.

    If your scenario includes removing the items of the RadRotator on the client, the removeRotatorItem (deletes a particular item) or clearItems (deletes all items) function will help you achieve this.

    Note that in the examples above I have referenced a rotator control with ID, set to RadRotator1, which may be different in your case.

    Reviewing the online demo Rotator / Client-side Items Management is also recommended, as it shows in action the methods, described above.

    I hope the provided information will help you incorporate the desired feature into your actual project.

    Kind regards,
