onclose and onbefore close are firing onopen???

[John]

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" %>
<telerik:RadWindowManager 
    runat="server" 
    RestrictionZoneID="offsetElement" 
    EnableShadow="true" 
    ShowOnTopWhenMaximized="false" 
    VisibleStatusbar="false"
    Behaviors="Close, Move, Resize, Maximize" 
    Opacity="99" 
    Height="400" 
    Width="400" >
</telerik:RadWindowManager>
 
<script type="text/javascript">
    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.SetTitle(title);
        wnd.setSize(width, height);
        wnd.set_modal(modal);
        if (onBeforeCloseEvent != null) {
            wnd.add_beforeClose(onBeforeCloseEvent);
        }
        if (onCloseEvent != null) {
            wnd.add_onClose(onCloseEvent);
        }
 
        return false;
    }
</script>

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", 765, 500, true, null, alert("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.SetTitle(title);
    wnd.setSize(width, height);
    wnd.set_modal(modal);
    if (onBeforeCloseEvent != null)
    {
        wnd.add_beforeClose(onBeforeCloseEvent);
    }
    if (onCloseEvent != null)
    {
        wnd.add_close(onCloseEvent);
    }

    return false;
}

Kind regards,

Thanks Martin. Everything's working as it should now.
