    I have a RadHtmlPlaceHolder that hosts a local page that contains an ActiveX control. I need to execute a javascript function of that ActiveX control from the main Silverlight project.

    Previously I have used the same control in one of your HtmlPlaceHolders for ASP.NET and had no problem executing a javascript function againt the embedded control like so:

    function SaveChangesBeforePostback() 
        var frame = window.frames["DocViewDock_C_DocView_frmDocView"]; 
        if (frame != null)  
            var frameDocument = frame.document; 
            if (frameDocument != null)  
                var myActiveXControl = frameDocument.getElementById("PageLayout_IrcDocViewer"); 
                if (myActiveXControl != null

    Is there a similar way I can access the embedded iframe like I did previously, thus allowing me to access the ActiveX object?

    Hello Andrew,

    Please have a look at this KB Article: Calling Javascript functions from RadHtmlPlaceholder

    Also, here is more on calling JavaScript from Managed Code.

    Let me know if this helps or your need further assistance on the topic.
