Refreshing parent page from a child page opened as a modal dialog boxOptions

    Default.aspx is the starting page containing a control(ascx) which
    has
    asp:button control on it. On the button click event it has to open a
    new page as a modal control. Since refreshing a page in a dialog box
    ended up opening up a new browser window with the aspx page, I read
    on
    a forum that I should use the iframe control and since I have to open
    a bunch of pages as diaogboxes, I created a general
    page(Container.aspx) which has an iframe control on it, which I then
    pass a parameter(pageToGoTo) specifying the aspx page that has to be
    opened as a dialogbox.

    Sequence of events and code are as follows:


    On the default.aspx page I have added a control with a button. On the
    button click server side event on that control, I call an aspx page.


    string script = String.Format("window.showModalDialog(\"{0}?
    pageToGoTo=testWebForm01.aspx\", \"testWebForm01.aspx
    \" ,'dialogWidth=520px;dialogHeight=650px;dialogTop=125px;dialogLeft=125px;');­",
    ResolveUrl("~/Container.aspx"));
    Page.ClientScript.RegisterStartupScript(GetType(),
    "test",
    script, true);


    On the Container.aspx I have an iframe control called frameTest which
    I load on Page_Load event as follows


    string pageToGoTo =
    Request.QueryString["pageToGoTo"];
    frameTest.Attributes["src"] = pageToGoTo;


    This is then able to load the testWebForm01.aspx in the iframe
    control.


    Now on a button click event on testWebForm01.aspx I want to close the
    testWebForm01 form and reload default.aspx so that the control on
    default.aspx. I added the following javascript code to
    testWebForm01.aspx


    function refreshParent()
    {
    window.opener.location.href = window.opener.location.href;


    if (window.opener.progressWindow)
    {
    window.opener.progressWindow.close()
    }
    window.close();


    // parent.refresh();
    // self.close();
    }


    and called it on the server side button_click event as follows


    string script = "refreshParent()";
    Page.ClientScript.RegisterStartupScript(GetType(),
    "test",
    script, true);


    I keep getting window.opener is null error.


    I read on another forum that if we have used showModalDialog method
    then window.opener method is not initialized.


    I did play around with trying to initialize it but haven't had any
    success.


    Does anybody have any idea on how refreshing the parent page can be
    accomplished? Please let me know.


    Thanks
