ASPX Page inside RadPageView

[Nelis]

I have a .ASPX page that is loaded server side using the ContentURL= property, server side when the user clicks on a tab using the RadTabStrip click event:

 protected void RadTabStrip1_TabClick(object sender, RadTabStripEventArgs e)
    {
        RadPageView pageView = AddPageView(e.Tab);
       
        switch (e.Tab.PageViewID)
        {
            case "DriverList":
                pageView.ContentUrl = "DriverList.aspx";
                break;
        }

        e.Tab.PageView.Selected = true;
    }

Inside the DriverList.aspx page I have a javascript function which I would like to call from the parent page where the MultiPage/PageView control is situated using client-side javascript.

    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">

            $(window).load(function () {
                window.parent.parent.HideLoadingPanel('DataPane');
            });

            function showAlert() {
                alert("Here");
            }
        </script>

I'm trying to call this javascript function from the onTabSelected client side event on the parent page:

function onTabSelected(sender, args) {
    var tab = args.get_tab();
    var value = tab.get_value();
    if (tab.get_pageViewID()) {

        var pageView = document.getElementById(tab.get_pageViewID());
        var contentWindow = pageView.getExtContentElement();
        contentWindow.showAlert();

    }
}

This is not working. Any advice ?

Hi Nelis,

When you have a PageView with ContentURL , the content of the website is situated in an iframe on the main page. You could call a function from DriverList.aspx with the following code:

function onTabSelected(sender, args) {


    var tab = args.get_tab();
    var pageview = tab.get_pageView();

    if (pageview.get_contentUrl() == "/TestWebSite3/DriveList.aspx") {
        $telerik.getChildrenByTagName(pageview.get_element(), "iframe")[0].contentWindow.showAlert()
    }
}

All the best,
