Hi,

I've run into a problem using standard server side code injecting javascript into a label to close a radwindow. The code works fine in IE and FF.

ASPX

        function GetRadWindow() {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz az well)
            return oWindow;
        }

        function CloseWindow() {
            GetRadWindow().Close();
        }

<body style="background-color: #EDF3FE; font-family: Arial; font-size: 12px; color: Navy;
    padding: 0px; margin: 4px; overflow: hidden">
    <form id="form1" runat="server">
    <asp:Label ID="lblJS" runat="server"></asp:Label>
etc...

aspx.cs

        protected void cmdCancel_Click(object sender, EventArgs e)
        {
            lblJS.Text = "<script language='javascript'>CloseWindow()</script>";
        }

When I execute the button click Chrome just displays "Aw Snap!"

Looking at Chrome's error console I see:

Failed To Load Resource http://localhost:50163/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a3bbfe379-348b-450d-86a7-bb22e53c1978%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2010.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a86f56c91-febb-4172-ae71-6c2ba2372421%3a16e4e7cd%3aed16cbdc%3af7645509%3a24ee1bba%3a1e771326%3aaa288e2d%3a8674cba1%3ab7778d6c%3ac08e9f8a%3aa51ee93e%3a59462f1

Any idea what's going on please?

Regards

Alan

Hello guys,

Can you please send a sample project that reproduces this problem? I tried to reproduce it locally but everything is working as expected. What I can suggest at this point (based on the code excerpt from Alan) is
1. Not to use a Label for outputting the JavaScript, but ScriptManager's RegisterStartupScript.
2. Try to call (in the JS function) GetRadWindow().close() with a small timeout.

I hope this helps.

Same problem here - but it seems to be localized to windows that display pdf's.
When 'DestroyOnClose=true' the AwSnap message appears right away, when false the Aw Snap message appears when navigating away from the page.

Doesn't seem to be an issue w/ Chrome on OSX.

The following code causes the issue as long as there is a 'sample.pdf' available:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

}

Hello again guys,

Another customer of ours just sent a sample project that reproduces the problem with the JavaScript outputted from the server. Again DestroyOnClose was set to true in that project. In such case you need to make sure that the script will be executed only when the content page is completely loaded.
e.g.

function CloseWindow()

{

Sys.Application.add_load(function ()

{

var rWindow = GetRadWindow();

rWindow.close();

});

}

Mike, unfortunately at this point I cannot provide a solution for your scenario. I was able to reproduce the problem and I logged it in our database (and updated your points). We will examine it and do our best to provide a solution as soon as possible.

This may be a workaround for the time being:
Add a OnClientBeforeClose handler and wrap an explicit call to radWindow.close() in a try catch block, stuffing any exceptions.

In Chrome the window will flash black before closing as the method seems to be called more than once - but will eliminate the Aw Snap message. Other browsers seem to close normally. Problem is after repeated openings and closings - eventually the crash returns.

<script type="text/javascript">

//Put your JavaScript code here.

function buttonClicked() {

radopen(null, "rwView");

}

function CloseWindow(sender, args) {

try {

sender.close();

} catch (err) {

//alert("Caught Exception: " + err.description);

return 0;

}

// sender = null;

}

</script>

<input id="button" type="button" value="Click Me!" onclick="buttonClicked();" />

<telerik:RadWindowManager ID="radWindowManager" runat="server" VisibleStatusbar="False"

Behaviors="Close, Move, Resize,Maximize" DestroyOnClose="true" OnClientBeforeClose="CloseWindow" >

<Windows>

<telerik:RadWindow ID="rwView" Width="600px" Height="600px" runat="server"

NavigateUrl="sample.pdf">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

Hi guys,

I just wanted to notify you that we found the reason for the problem - it comes from the new feature in Chrome which provides additional security:
http://blog.chromium.org/2010/05/security-in-depth-html5s-sandbox.html

This new feature interferes with the way we dispose the RadWindow and we are currently investigating the possible fixes. I will write back once we have more information.

Best wishes,
