confirm if radwindow must be close. (Showing a radconfirm on close of a window )

[nenita]

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)
        {
            sender.remove_beforeClose(onBeforeClose);
            sender.close();
        }
    }
arg.set_cancel(true);
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
//wnd.add_beforeClose(onBeforeClose);
//sender.add_beforeClose(onBeforeClose);

//but this work. its a closing event not before close
wnd.add_close(onBeforeClose);
}

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:
http://www.telerik.com/community/code-library/aspnet-ajax/window/confirm-closing-of-a-radwindow-by-using-radconfirm.aspx

        function OpenWindow(sender, eventArgs)
        {
            radopen("http://www.google.com","RadWindow2");
            //Make sure to pass the correct window name as
            //an argument when calling the ConfirmClose() function

            ConfirmClose("RadWindowWrapper"+"_"+"RadWindow2",sender,eventArgs);
        }

        function ConfirmClose(WinName,sender,eventArgs)
        {
            var oManager = GetRadWindowManager();
            var oWnd = oManager.GetWindowByName(WinName);
            var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");


            $("a.closebutton").click(function(){
            // prompt box code
                alert('x');
                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);
                    oWnd.Close();
                }
        }

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)){
_24.set_cancel(true);

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.

before:

<li>
<a class="closebutton" href="javascript:void(0);" title="Close">
<span>Close</span>
</a>
</li>

later: I see this using an inspector,  this is the result:

<a 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:

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

it's that the problem?

Any idea its helpful.
Very thank you in advance.

Nenita.

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:

http://www.telerik.com/community/forums/aspnet-ajax/window/close-the-rad-window.aspx

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,
