    Ok I'm kinda new to the Telerik tools so hope this doesn't sound too strange...

    I created a user control with the RadWindowManager and a jscript function to open the window as below:

    <%@ Control Language="VB" AutoEventWireup="false" CodeFile="RadWindowManager.ascx.vb" Inherits="Controls_RadWindowManager" %>
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
        Behaviors="Close, Move, Resize, Maximize" 
        Width="400" >
    <script type="text/javascript">
        function OpenRadWindow(urltitlewidthheightmodalonBeforeCloseEventonCloseEvent) {
            if (url == null) { url = "" }
            if (title == null) { title = "" }
            if (width == null) { width = 400 }
            if (height == null) { height = 400 }
            if (modal == null) { modal = true }
            var wnd = window.radopen(urlnull);
            if (onBeforeCloseEvent != null) {
            if (onCloseEvent != null) {
            return false;

    The idea was to not have to declare it all over the place as we have many popups in our system and some require different variables than others.

    Anyways Part 2:

    In one of my pages I have a popup that requires some inputs and such and needs to refresh the main page when it closes.

    <%@ Register Src="~/Controls/RadWindowManager.ascx" TagName="RadWindowManager" TagPrefix="uc3" %>
    <uc3:RadWindowManager ID="RadWindowManager" runat="server" />
    function OpenAddProduct() {  
                var url = <%= """" & ResolveUrl("~/Levels/Products.Aspx?Popup=1") & """" %>;
                OpenRadWindow(url"Manage Products"765500truenullalert("This is supposed to be a close event..."));

    Obviously what I am expecting is when the window is closed an alert to popup with that message, however what I am getting is that as soon as the window opens it is firing the OnClose event the same goes for the OnBeforeClose as well.

    Am I just doing something wrong here declaring the window or is there more to it???

    Hi John,

    You need to feed a variable of type function to the methods of the RadWindow that handle its events. In your current code the object that is the onCloseEvent variable is actually a call to the alert, not to a function, so once it gets accessed it gets executed.

    Another problem is that the add_close() method is misspelled in your case to add_onClose. The list with the available methods is available in this help article.

    That being said, the following syntax should get things going:
    function OpenAddProduct()
        function someFunction() { alert("This is supposed to be a close event..."); }
        OpenRadWindow(url, "Manage Products", 765, 500, true, null, someFunction);

    function OpenRadWindow(url, title, width, height, modal, onBeforeCloseEvent, onCloseEvent)
        if (url == null) { url = "" }
        if (title == null) { title = "" }
        if (width == null) { width = 400 }
        if (height == null) { height = 400 }
        if (modal == null) { modal = true }
        var wnd = window.radopen(url, null);
        wnd.setSize(width, height);
        if (onBeforeCloseEvent != null)
        if (onCloseEvent != null)
        return false;

    Kind regards,
