    I'm adding a jqplot chart to a page that has a RadTabStrip and a RadMultiPage on it. If I put the target <div> for the plot outside of the RadMultiPage, the chart gets rendered. If I put the target <div> inside the RadMultiPage, however, it doesn't get rendered. This makes me think the JavaScript that's attempting to render the chart in the <div> can't find it.

    How should I refer to the <div> in my JavaScript?

    Here's how my <div> is defined?
    <div id="chartdiv" style="height:300px; width:600px; border: none;"></div>

    Here's the JavaScript that references the <div> and how it's placed in the RadPageView:
    <telerik:RadPageView ID="Achievement" runat="server">
        <div class="responseDiv"><asp:Label ID = "AchievementLabel" runat="server"></asp:Label></div>
        <script type="text/javascript">
            (function ($) {
                $(window).load(function () {
                    var exceedPoints = [['3rd', 218], ['4th', 223]];
                    var plot1 = $.jqplot('chartdiv', [exceedPoints], {
                        seriesDefaults: { pointLabels: { show: true } },
                        series: [{ label: 'Exceed' }],
                        grid: { drawGridlines: false },
                        seriesColors: ['#666699'],
                        title: 'Reading Scores'

    Hi Bryan,

    By default the RadPageView is rendered as a div element so it should not prevent the "chartdiv" to be found.  After further testing it seems that the chart is not rendered when the div is placed inside a hidden container such as the RadPageView before it's shown. If the pageview is set as selected upon initial load then the chart is properly rendered.

    Since I presume that the RadMultiPage is being used with RadTabStrip control, I've prepared a sample page showing how to deal with the experience problem.

    All the best,
