Persisting RadRotator's CoverFlow Animation Through an AJAX Request

In some scenarios you may need to Ajaxify the RadRotator control on your page. Please keep in mind that if you have set the rotator control in CoverFlow mode (RotatorType=”CoverFlow”), the script that configures its animation options should be registered from the code-behind in order to persist the animation through the Ajax request.

The following example demonstrates how to set the animation options if a RadRotator in CoverFlow mode is placed in an UpdatePanel control.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <telerik:RadRotator RenderMode="Lightweight" ID="RadRotator1" runat="server" RotatorType="CoverFlow" ScrollDirection="Left,Right"
            Height="233px" ItemHeight="113px" Width="490px" ItemWidth="150px">
            <ItemTemplate>
                <img src="........" alt="" />
            </ItemTemplate>
        </telerik:RadRotator>
        <asp:Button ID="Button1" Text="Send Request" runat="server" />
    </ContentTemplate>
</asp:UpdatePanel>

protected void Page_Load(object sender, EventArgs e)
{
    string script = "var animationOptions = {" +
     "minScale: 0.8," +
     "yO: 60," +
     "xR: -30," +
     "xItemSpacing: 50," +
     "matrix: { m11: 1, m12: 0, m21: -0.1, m22: 1 }," +
     "reflectionHeight: 0.5," +
     "reflectionOpacity: 1" +
    "};" +
    "Telerik.Web.UI.RadRotatorAnimation.set_scrollAnimationOptions('" + RadRotator1.ClientID + "', animationOptions);";

    ScriptManager.RegisterStartupScript(this, this.GetType(), "registerCoverFlowAnimation", script, true);
}

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
    Dim script As String = "var animationOptions = {" +
     "minScale: 0.8," +
     "yO: 60," +
     "xR: -30," +
     "xItemSpacing: 50," +
     "matrix: { m11: 1, m12: 0, m21: -0.1, m22: 1 }," +
