[Solved] Accessing the Content of the HtmlPlaceHolder

[Andrew]

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)
            {
                myActiveXControl.ExSaveAnnoChanges();
            }
        }
    }
}

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.
