    Hi, me again, I need to do the same like its exposed on the forum:
    some similar
    but I have different mistakes, this is the scenario:

    function onBeforeClose(sender, arg)  
        function callbackFunction(arg)  
            if (arg)  
    radconfirm("Are you sure", callbackFunction, 300, 100, null"Close RadWindow");  
    //this function call a window when I click a menu item 
    function menuClick(sender,arg)  
    //show window .... 
    //this comment lines not work, I try both 
    //but this work. its a closing event not before close 

    and when i close this its the message error: arg.set_cancel is not a function,
    I  read on the forum something like if its no the right method this error shows but, 'add_beforeClose' dont work to me yet.
    there another way to call this event?
    I'm a litle confused.
        Thanks in advance.

    I solve a litle piece of my problem. I do the following
    include a jquery script and  found the class called when I click the close button because this dont have Id its something like this:
    I adapt one example from here:

            function OpenWindow(sender, eventArgs) 
                //Make sure to pass the correct window name as  
                //an argument when calling the ConfirmClose() function 
            function ConfirmClose(WinName,sender,eventArgs) 
                var oManager = GetRadWindowManager();            
                var oWnd = oManager.GetWindowByName(WinName); 
                var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");     
                // prompt box code 
                    eventArgs.set_cancel(true);//dont work. 
                    radconfirm("Are you sure", confirmCallBackFn, 300, 100, null"Cerrar Ventana?");  
                    //cancelar cierre de ventana 
            function confirmCallBackFn(arg) 
                if (arg == true
                        var oManager = GetRadWindowManager(); 
                        var oWnd = oManager.GetWindowByName(CurrentWinName); 

    but my problem now its the argument come empty, I dont kwon well how to request them.
    I found this code maybe generate automaticly  inside my page I think if I know well what are the parameter maybe I can stop the close execution  RadAjaxRequestEventArgs seems to request the arguments and later cancels, but I dont kwon really well.

    var evt=new Telerik.Web.UI.RadAjaxRequestEventArgs(this.__EVENTTARGET,_23._form["__EVENTARGUMENT"].value,this._enableAJAX); 
    var _2b=this.fireEvent(this,"OnRequestStart",[evt]); 
    if(evt.get_cancel()||(typeof (_2b)!="undefined"&&!_2b)){ 

    There are any function to overwrite like when we try to change the appereance skin?

    By any help Thanks in advance.
    pd: sorry for my english

    I progress a litle, using Jquery, replace many atributes from the button,
    1. I remove the span tag inside a.closebutton 
    2. I replace the href atribute: before: javascript:void(0); later:""
    3. I change the name of the button and put them "cerrar"
    4. put in my css a new class for the new button.

    <class="closebutton" href="javascript:void(0);" title="Close"

    later: I see this using an inspector,  this is the result:
    <class="cerrar" href="" title="cerrar" onclick="javascript:cerrar();"/> 

    but anyway when I click the result its the same -> close the window.

    inside my code I found this:
                    <a  onclick="$find('{0}').close();" 
                    class="radwindowbutton" href="javascript:void(0);"
                        <span class="outerspan"
                            <span class="innerspan">##LOC[OK]##</span> 

    it's that the problem?

    Any idea its helpful.
    Very thank you in advance.

    Hi nenita,

    Your initial approach should work in the common case - I prepared for you a sample demo based on it which works as expected - please see the attached demo. One possible problem could be that you are using a very old version of RadWindow where the OnClientBeforeShow event is still not implemented (the event is introduced in the 2008.3.1314 release). If so, I suggest to upgrade to the latest release. If this is the case and you do not want to upgrade, you can override the default close function as shown below:

    In case you are using a later version than the mentioned one, please examine the attached demo which I prepared for you - just modify it in order to reproduce the problem, open a new support ticket and send it to me along with detailed reproduction steps and explanations.

    Kind regards,
