I have implemented CoverFlowMode using Radrotator, as there are huge records I am implemeting paging manually using RadAjaxManager Ajax Request on button click.

But the RadRotator is not getting updated with next records using RadAjaxManager. How can I update Radrotator CoverFlowMode with RadAjaxManager.

Below is the code
aspx file code

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function ClientClicked() {

$find(

<%= rmStudentList.ClientID %>").ajaxRequest("NEXT");
return false;

}
</script>
< /telerik
:RadCodeBlock >

<div class="mainDiv">
<asp:Panel ID="RotatorWrapper" runat="server" CssClass="rotWrapper">

<telerik:RadRotator ID="RadRotator1" runat="server" Width="748px" ItemWidth="150"

ScrollDirection="Left, Right" Height="233px" ItemHeight="113" ScrollDuration="500"

FrameDuration="2000" PauseOnMouseOver="false" RotatorType="CoverFlow" InitialItemIndex="4"

OnClientItemShown="OnClientItemShown" OnClientItemClicked="OnClientItemClicked"

CssClass="RemoveRotatorBorder">
<ItemTemplate>

<asp:Image ID="Image1" runat="server" ImageUrl='<%# GetImagePath(Eval("ImagePath")) %>'

AlternateText='<%# Eval("LastName") %>' />

</ItemTemplate>

</telerik:RadRotator>

<input id="Button1" type="button" runat="server" value="Next" onclick="ClientClicked(); return false;" />

</asp:Panel>

</div>

cs file

protected void rmStudentList_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

ConfigureRadRotator(RotatorType.CoverFlowButtons);

}

Hello Neeraj,

Please check the support ticket on the same problem, in which I have provided a solution to the problem at hand. For your convenience I will post the answer here as well:

Overall, your approach for updating the RadRotator seems to be correct - you are rebinding it with new data of every Ajax request. Please check if the data that is loaded in the RadRotator after the Ajax request isn't the same as before.

Also, when Ajaxifying a rotator control in CoverFlow mode, you should register the animation options script on every request to the server in order to preserve the CoverFlow animation effects:
protected void rmStudentList_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    ViewState["PageIndex"] = "4";
    ConfigureRadRotator(RotatorType.CoverFlowButtons);
    string script = "Telerik.Web.UI.RadRotatorAnimation.set_scrollAnimationOptions('" + RadRotator1.ClientID + "', {minScale: 0.8, yO: 60, xR: -30, xItemSpacing: 50, matrix: { m11: 1, m12: 0, m21: -0.1, m22: 1 }, reflectionHeight: 0.5, reflectionOpacity: 1 });";
    ScriptManager.RegisterStartupScript(Page, Page.GetType(), "setupAnimation", script, true);
}

I have prepared a sample project that uses your code in order to implement the core functionality that you want to achieve. Please use it as a reference for incorporating this feature into your actual project.

For future use of our support system I would suggest sending a separate ticket for every problem that you want to report. This will ease our correspondence and we'll be able to provide a working solution much faster if there is only one ticket to follow. That being said, let's continue our discussion in your support ticket on the matter.
