Hello Greg,

This problem has been reported a couple of times - indeed it does not occur regularly and it is difficult to duplicate. That said, we have changed the code so that the problem does not occur anymore. Hence, the reason for the problem would seem that you are using an older Telerik.Web.UI version. I suggest you try either the current Q1 2009 or (in case you are not able to upgrade to it for some reason) - the older Q3 2008 SP2.

I'm running into an issue when attempting to use a RadConfirm from inside a simple repeater. I've used Xcalibur's technique with great success outside of a repeater.

Its a simple LinkButton with an OnClick C# event. As I'm binding the repeater I'm setting up the OnClientClick event for the button.

Javascript:

    
            <script type="text/javascript"> 
        
            var btnName = ""; 
        
            function setButtonClientID(clientID, text, title)  
        
            { 
        
                btnName = clientID; 
        
                radconfirm(text, ClientCallback, 480, 180, '', title);  
        
            } 
        
            var ClientCallback = function (arg)   
        
            { 
        
                alert('btnName: ' + btnName + ' arg: ' + arg); 
        
                if (arg)  
        
                { 
        
                    __doPostBack(document.getElementById(btnName), ''); 
        
                } 
        
            } 
        
            </script>

ASPX:

    
            <asp:LinkButton ID="btnRemove" runat="server" CommandArgument='<%#  Eval("ElementID") %>' CommandName="Remove" CssClass="button_100"> 
        
            <span class="cancel">Remove</span> 
        
            </asp:LinkButton>

C#:

    
            btnRemove.OnClientClick = "setButtonClientID('" + btnRemove.ClientID + "', 'Remove this Element?' , 'Confirm Remove?'); return false;";

You'll notice in my Javascript that I'm using

var ClientCallback = function (arg)

according to the "post-confirmation" logic stated in Reply #3

The radconfirm comes up after pressing the btnRemove as expected along with the cancel button canceling the postback correctly. The alert that I call returns the expected variable strings, however when I press the 'OK' button I receive an error "Microsoft JScript runtime error: Object doesn't support this property or method" with "_uniqueIDToClientID:function(a){return a.replace(/\$/g,"_")}" highlighted in my Telerik.Web.UI.WebResource.axd

Thanks in advance for any help!

-Daniel

Hello again Daniel,

After receiving your project I noticed the problem in the code that I have missed in my previous reply - sorry about that.
The _doPostBack() function accepts as a first parameter the ID of the element, not the object itself. If you change your code to
__doPostBack(document.getElementById(btnName).id, '');
it will work as expected.

Hi Georgi,

I am intercepting RadAjaxManager ClientEvents-OnRequestStart with the following ...

function

OnRequestStart(ajaxControl, eventArgs) {

    var eventTarget = eventArgs.EventTarget;

    var element = document.getElementById(eventTarget);

    var iframe = document.frames[iframeids[0]];

    var latestStepIndex = 0;


    if (typeof iframe != 'undefined')

        latestStepIndex = iframe.latestStepIndex;

    if (typeof latestStepIndex != 'undefined' && latestStepIndex > 0) {

        var complete = confirm('Are you sure?');

        if (!complete) {

            if (element.type == 'select-one') {

                if (eventTarget != 'lstType')

                    element.selectedIndex = controlValues[eventTarget];

                else

                    element.selectedIndex = -1;

            }

            else if (eventTarget == 'rblOriginator')

                setRadioButtonListSelectedIndex(element, controlValues[eventTarget]);

         }


        return complete;

    }

    else {

        if (element.type == 'select-one')

            controlValues[eventTarget] = element.selectedIndex;

        else if (eventTarget == 'rblOriginator')

            controlValues[eventTarget] = getRadioButtonListSelectedIndex(element);

        return true;

    }

}

The page with ajax manager has a menu which then loads a different page (living in a different application) into an iframe. If the user is so far through the wizard in the iframe and then clicks a menu option. Menu selection fires of ajax call (and method above) and I ask the user if they are sure they want to reload page in iframe. If not sure then I cancel request and reinstate the menu control previous value. This works like a dream using the standard confirm box. Is it possible to use the RadConfirm in this scenario and if so how would this be done?

Thanks
John

Hello John,

I'm afraid this is not possible. As noted in this code library, radconfirm, radalert and radprompt cannot block the execution thread like the standard popups. The solution that is provided here mimic such behavior, but it cannot be applied to your case.

I'm using this code with success to catch if a page is dirty before navigating away and displaying the radconfirm instead of the default IE javascript confirmation dialog.

My question is, we're using a ConfirmDialogType="RadWindow" on a Telerik GridButtonColumn, which seems to map to the radconfirm call. Throughout other places in our app, I had to change all previous references from radcofirm to "oldRadConfirm" (as demonstarted in the example).

Is there anyway to map the RadWindow in ConfirmDialogType to oldRadConfirm, so this works?

Thanks.

Hi David,

If you use RadControls for ASP.NET AJAX, then I recommend you to use this simple approach in order to block the execution thread with radconfirm.

I hope this helps.

Hello,

My environment is VS 2010 with Telerik Telerik.Web.UI version 2009.3.1314.35.

I managed to reproduce the beahviour has expeted in IE, ie, I have a remove button, when I press the button I get the confirmation window.

But in FF 3.6.3 the behaviour is somewhat unexepected: when I press the button I get the confirmation window but if I press "OK" nothing happens, but when I press a second time than the browser doesn't show any confirm message and immediately execute the code-behind code. Thus the steps in FF are: 1) Press button remove; 2) Press OK in the radalert window; 3) Press button remove again; 4) Browser executes automatically the code-behind.

Here is the code:

    
            <telerik:radwindowmanager id="radInfoWindow" runat="server" > 
        
                        </telerik:radwindowmanager> 
        
                        <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">   
        
                            <script type="text/javascript"> 
        
                                //MAKE SURE THAT THE FOLLOWING SCRIPT IS PLACED AFTER THE RADWINDOWMANAGER DECLARATION 
        
                                //Replace old radconfirm with a changed version.    
        
                                var oldConfirm = radconfirm; 
        
                                //TELERIK 
        
                                //window.radconfirm = function(text, mozEvent) 
        
                                //We will change the radconfirm function so it takes all the original radconfirm attributes

Hi Regula,

As noted in all articles that reference the workaround that you are using, this code is considered a hack and we do not guarantee that it will work in all cases.
What I can suggest in your case, is to use RadAjaxManager and its ajaxRequestWithTarget() function - please find attached a small sample that shows how to achieve the desired result.

Best wishes,

Hi All,

has this "blocking" behaviour been implemented yet as a standard feature in the radconfirm method ?

or do we still have to use the "workaround" as provided in this thread ?

Hello Dr. Evil,

There is no "ultimate" solution that would produce consistent result in all browsers and in all scenarios, like the standard confirm popup. That is why the approach, described here, hasn't been implemented in radconfirm - as noted before, the approach is considered a hack and it works in certain scenarios only.

All the best,

Hello,

I took this callback blocking exec solution and implemented into a project. But I work when the page is "ajaxified".

I have the following ajaxsetting in my radajaxmanager:

   <telerik:AjaxSetting AjaxControlID="btnUpdate">
   <UpdatedControls>
   <telerik:AjaxUpdatedControl ControlID="btnUpdate" />
   <telerik:AjaxUpdatedControl ControlID="ResponseControl1" />
   </UpdatedControls>
   </telerik:AjaxSetting>

ResponseControl1 is a custom control on our side.

Here is what btnUpdate looks like:

   <asp:Button ID="btnUpdate" Text="Submit" runat="server" OnClientClick="return blockConfirm('Are you sure you want to submit?', event, 250, 100,'','Submit?');"
   Visible="false" CommandName="Update" SkinID="MPPSkin" OnClick="btnUpdate_Click" />

Note the visible="false" is set back to true on page_init. When I tried to execute the button click, I get the confirmation window. But when I click yes in the confirm window, the code behind of the button click doesn't get executed. But if I remove the ajaxsetting for btnUpdate, everything executes.

How can I make this code "ajaxified"?

thanks,
Luis

BTW - i'm using the blocking execution code that is posted on the telerik demo website for radwindow:

Hello Luis,

I recommend you to use this very simple approach in order to achieve the desired result:

ASPX:

<head id="Head1" runat="server">

    <title></title>

    <script type="text/javascript">

        function blockConfirm(clickedButton)

        {

            function confirmHandler(args)

            {

                if (args == true)

                {

                    __doPostBack(clickedButton.name, "");

                }

            }

            radconfirm('Are you sure you want to submit?', confirmHandler, 250, 100, null, 'Submit?')

            return false;

        }

    </script>

</head>

<body>

    <form id="form1" runat="server">

    <asp:ScriptManager ID="Scriptmanager1" runat="server">

    </asp:ScriptManager>

    <telerik:RadWindowManager ID="RadWindowManager1" runat="server">

    </telerik:RadWindowManager>

    <telerik:RadAjaxManager IS="RadAjaxManager1" runat="server">

        <AjaxSettings>

            <telerik:AjaxSetting AjaxControlID="btnUpdate">

                <UpdatedControls>

                    <telerik:AjaxUpdatedControl ControlID="btnUpdate" />

                    <telerik:AjaxUpdatedControl ControlID="ResponseControl1" />

                </UpdatedControls>

            </telerik:AjaxSetting>

        </AjaxSettings>

    </telerik:RadAjaxManager>

    <asp:Button ID="btnUpdate" Text="Submit" runat="server" OnClientClick="return blockConfirm(this);"

        Visible="false" CommandName="Update" SkinID="MPPSkin" OnClick="btnUpdate_Click" />

    <asp:Label ID="ResponseControl1" runat="server"></asp:Label>

    </form>

</body>

</html>

Codebehind:

protected void Page_Init(object sender, EventArgs e)

{

    btnUpdate.Visible = true;

}

protected void btnUpdate_Click(object sender, EventArgs e)

{

    ResponseControl1.Text = DateTime.Now.ToString();

}

I hope this helps.

Hi there,

I use the code snipped which was here provided to block the excecution within the RadConfrim.

But it seems that this is not longer working with firefox 5.
Can you confirm this?
On FF5 just nothing happens - no javascript error or something like this.

Thank you!
Felix

Hello Felix,

The original post and code have been prepared for older versions of the .NET framework and the RadControls for ASP. As noted in previous replies this approach is generally considered to be a hack and it is not guaranteed that it will work in all cases.

Please try using the newer version which only uses a callback function instead of overriding the entire radconfirm() method.

That being said the following code seems to work fine under FF5 as well:

<asp:Button ID="Button1" Text="text" runat="server" OnClientClick="return blockConfirm(this);" OnClick="Button1_Click" />

function blockConfirm(clickedButton)

{

    function confirmHandler(args)

    {

        if (args == true)

        {

            __doPostBack(clickedButton.name, "");

        }

    }

    radconfirm('Are you sure you want to submit?', confirmHandler, 250, 100, null, 'Submit?')

    return false;

}

Please note that in the case of a link button you would need to pass its id and not its name to the __doPostBack() function.

All the best,
Marin

Consider using RadControls for ASP.NET AJAX (built on top of the ASP.NET AJAX framework) as a replacement for the Telerik ASP.NET Classic controls, See the product support lifecycle here.

Hi Marin,

thank you for your quick response.

The solution you provided looks fine but we implemented about 50 radconfirm-calls in our software.
So this is a whole bunch of time we had to spend on re-implementing this.

Is there any other soloution?
Or could you tell us if there is a fault on mozillas side causing this problem or is this a problem on your side?
If found this bug according to FF5 (https://bugzilla.mozilla.org/show_bug.cgi?id=666955) and Telerik Ajax.
Could this have something to to with our problem?

Thanks again,
Felix

Hello Felix,

This code has been created years ago for the RadControls for ASP suite, which is not designed to work with AJAX. Therefore when AJAX is introduced you will experience some unexpected behavior with it - namely - it does not work when the initiators perform an AJAX request and not a postback.

What I would advise is that you do not use this hack, but move to using the callback function as shown in the later posts.

That being said - I cannot confirm if this issue with FF5 is related to this case, but it seems that the guys from Mozilla are changing the behavior related to the client-side click() method for links and it is yet to be seen and tested what will come of it.

Greetings,
Marin

Consider using RadControls for ASP.NET AJAX (built on top of the ASP.NET AJAX framework) as a replacement for the Telerik ASP.NET Classic controls, See the product support lifecycle here.

try this:

var originalRadConfirm = radconfirm;

window.radconfirm = function(text, mozEvent, oWidth, oHeight, callerObj, oTitle) {

    var ev = mozEvent ? mozEvent : window.event;

    ev.cancelBubble = true;

    ev.returnValue = false;

    if (ev.stopPropagation) ev.stopPropagation();

    if (ev.preventDefault) ev.preventDefault();



    var callerObj = ev.srcElement ? ev.srcElement : ev.target;



    if (callerObj) {

        var callBackFn = function(arg) {

            if (arg) {

                callerObj["onclick"] = "";

                var isFF = false;

                if (window.$telerik && window.$telerik.isFirefox) {

                    isFF = true;

                }

                if (callerObj.click && !isFF) {

                    callerObj.click();

                }

                else if (callerObj.tagName == "A")

                {

                    try {

                        eval(callerObj.href)

                    }

                    catch (e) { }

                }

            }

        }

        originalRadConfirm(text, callBackFn, oWidth, oHeight, callerObj, oTitle);

    }

    return false;
