Hello Robson L,

Here is a sample code snippet that achieves the desired effect:

ASPX:

<asp:ScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadCodeBlock ID="cb1" runat="server">

<script type="text/javascript">

function pageLoad() {

window.setTimeout(refresh, 1000);

}

function refresh() {

var ajaxPanel = $find("<%= RadAjaxPanel1.ClientID %>");

ajaxPanel.ajaxRequest("");

}

</script>

</telerik:RadCodeBlock>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" OnAjaxRequest="RadAjaxPanel1_AjaxRequest">

<telerik:RadChart ID="RadChart1" runat="server">

</telerik:RadChart>

</telerik:RadAjaxPanel>

C#:

private Random rand = new Random(DateTime.Now.Millisecond);

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

RadChart1.DataSource = new int[] { rand.Next(10, 100), rand.Next(10, 100), rand.Next(10, 100) };

RadChart1.DataBind();

}

protected void RadAjaxPanel1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

RadChart1.DataSource = new int[] { rand.Next(10, 100), rand.Next(10, 100), rand.Next(10, 100) };

RadChart1.DataBind();

}
