Hi Telerik,

I am experiencing this issue on Google Chrome 15.0.874.106 m using Telerik.Web.UI.dll v 2011.2.915.35

I have a RadWindow which points to a separate .aspx page. While this window is loading I take the liberty of setting the state of some controls. I am experiencing something very quirky when I enable my input control, though.

I have attached a 'before' and 'after' picture to this thread, but I've got some explaining to do, too. I put this through a couple of hours of testing and discovered some pretty weird discrepancies in functionality, which I would like to draw attention to.

Alright, so, here's the code-behind for the page the RadWindow points to:

<%@ Page Language="C#" EnableViewState="False" AutoEventWireup="True" CodeBehind="CustomLocalSettings.aspx.cs" Inherits="CableSolve.Web.Dashboard.Dialog.Windows.CustomLocalSettings" %>

<%@ Import Namespace="CableSolve.Web.Controllers.Managers" %>

</div>

</form>

</body>

</html>

Note that for my example the most-relevant portion of the code is located within the "RefreshProperties" div.
In addition, note that I am able to reproduce this issue with the CSS file commented out. I'll provide it at the end of this document just for the sake of it, but you should not need it.

//SharedSettingsFunctionality.js

//Contains functionality that all the dialog windows share in common. I found that I was maintaing a lot of code in multiple places unnecessarily.

function GetRadWindow() {

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow;

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;

return oWindow;

}

function OnGetDockAttributesFailure(errors) {

alert(errors);

}

function SetAutoRefreshState() {

var autoRefreshNumericTextBox = $find(window.autoRefreshNumericTextBoxID);

var wrapperElement = $get(autoRefreshNumericTextBox._wrapperElementID);

var label = $(wrapperElement.getElementsByTagName("label")[0]);

if ($('#' + window.autoRefreshCheckBoxID).is(':checked')) {

autoRefreshNumericTextBox.enable();

label.addClass("LabelEnabled");

label.removeClass("LabelDisabled");

}

else {

autoRefreshNumericTextBox.disable();

label.addClass("LabelDisabled");

label.removeClass("LabelEnabled");

}

//CustomLocalSettings.js

function pageLoad() {

var oWindow = GetRadWindow();

var dockID = oWindow.argument;

if (dockID) {

InitializeForm(dockID);

}

oWindow.argument = null;

}

function InitializeForm(dockID) {

SetAutoRefreshState();

$('#' + window.autoRefreshCheckBoxID).click(SetAutoRefreshState);

window.PageMethods.GetDockAttributes(dockID, OnGetDockAttributesSuccess, OnGetDockAttributesFailure);

}

//Pass the dialog data back to Dashboard.

function CloseAndSave() {

var oWindow = GetRadWindow();

var customAttributes = {};

customAttributes["RefreshEnabled"] = $('#' + window.autoRefreshCheckBoxID).is(':checked');

customAttributes["RefreshInterval"] = $find(window.autoRefreshNumericTextBoxID).get_value();

customAttributes["ChartType"] = $find(window.chartComboBoxID).get_value();

oWindow.argument = customAttributes;

oWindow.close();

oWindow.argument = null; //Important because pageLoad gets called once more after oWindow closes.

}

function OnGetDockAttributesSuccess(result) {

var dockData = $.parseJSON(result);

//Change the initial loading state based on the dock's known settings.

if (dockData["RefreshEnabled"]) {

$('#' + window.autoRefreshCheckBoxID).attr('checked', true);

var autoRefreshNumericTextBox = $find(window.autoRefreshNumericTextBoxID);

autoRefreshNumericTextBox.set_value(dockData["RefreshInterval"]);

autoRefreshNumericTextBox.enable();

var wrapperElement = $get(autoRefreshNumericTextBox._wrapperElementID);

var label = $(wrapperElement.getElementsByTagName("label")[0]);

label.addClass("LabelEnabled");

label.removeClass("LabelDisabled");

}

$find(window.chartComboBoxID).findItemByValue(dockData["ChartType"]).select();

$('#Content').show();

GetRadWindow().autoSize();

}

Okay, once again, most of this is not necessary -- but if it came down to it I wanted Telerik to be able to build easily.

Anyway, the following code executes:

CustomLocalSettings - pageLoad (calling InitializeForm);
CustomLocalSettings - InitializeForm (calling SetAutoRefreshState );
SharedSettingsFunctionality - SetAutoRefreshState: This method sets my input controls to disabled initially on default behavior.

At this point the code relevant to this discussion has fired, the window loads, and looks fine. AutoRefreshNumericTextBox is disabled, as well as it's associated CheckBox. The user then clicks the CheckBox to enable the AutoRefreshNumericTextBox. When it becomes enabled, the input holds its location but the label and arrow-adjuster break from their div and drop.

This in itself wasn't that weird, bugs happen, but there's some other weird things to mention:

I have this exact same code on another dialog window which uses ContentTemplate instead of directing to a separate page. It does not experience this issue. Only having the FormDecorator on a page which is loading seems to cause the issue.
If I tell FormDecorator to use DecorationZoneID = "Content" then I see a change in the error. Instead of arising when the input control becomes enabled (the control enables fine..), I see the div break out when I press the 'Up' arrow on the RadNumericTextBox.
Similarly, if I tell the control to skip decorating TextBox's, the control renders fine until I press the 'Up' arrow.

If I disable the FormDecorator I do not see any issues.

I performed a diff of the HTML mark-up being rendered before/after the control breaks from the div. The only change I saw, other than the CssClass changing from LabelEnabled to LabelDisabled, was that the RadNumericTextBox gained maxlength="524288"

The control does not gain this property when it is loaded inside of the ContentTemplate RadWindow.

Hi Sean,

I have tried to reproduce the issue, but to no avail. Find attached a sample project with my test. In Chrome and in disabled and enabled mode everything works as expected.

I have modified a little the project in order to run it. Could you check what I missed in order to reproduce the issue?

All the best,

Hi Bozhidar,

Thank you for your quick response. After looking at the project you provided I was able to find the root cause. I believe the error lies on Telerik's shoulders, though. I will explain and provide a simplified, running sample project with this thread.

TL;DR: (Something's) not conforming to the HTML5 spec.

http://dev.w3.org/html5/spec/syntax.html#the-doctype

8.1.1 The DOCTYPE

A DOCTYPE is a required preamble.

DOCTYPEs are required for legacy reasons. When omitted, browsers tend to use a different rendering mode that is incompatible with some specifications. Including the DOCTYPE in a document ensures that the browser makes a best-effort attempt at following the relevant specifications.

A DOCTYPE must consist of the following components, in this order:

A string that is an ASCII case-insensitive match for the string "<!DOCTYPE".
One or more space characters.
A string that is an ASCII case-insensitive match for the string "html".
Optionally, a DOCTYPE legacy string or an obsolete permitted DOCTYPE string (defined below).
Zero or more space characters.
A U+003E GREATER-THAN SIGN character (>).

In other words, <!DOCTYPE html>, case-insensitively.

Here's a sample project demonstrating incorrect behavior. I've removed as many dependencies as I can. I left the need for jquery-1.6.4.js, but moved all other css and javascript into the markup files.

<NumberFormat DecimalDigits="0" AllowRounding="False" />

</telerik:RadNumericTextBox>

</div>

</fieldset>

</form>

</body>

</html>

both .cs files are blank.

Run the above code and observe that a RadWindow pops up with one fieldset, checkbox, and input control. They all look properly formatted. Yet, if you check the checkbox the input controls breaks free.

Now, observe that if you modify the DOCTYPE tag away from the HTML5 standard to the "obsolete permitted DOCTYPE string" which is used in Default.aspx, the bug goes away.

A DOCTYPE containing an obsolete permitted DOCTYPE string is an obsolete permitted DOCTYPE. Authors should not use obsolete permitted DOCTYPEs, as they are unnecessarily long.

Thanks for looking into this.

Hi Glen,

Thank you for your time to explain the details of the issue. I succeeded to reproduce and found that that bug is already fixed and the fix is available in the latest internal build. However, if you do not want to download it, here I`m providing a simple JavaScript fix that will allow you to use FromDecorator on your pages in Chrome and Safari and to have nicely decorated form elements:

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

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

<html xmlns="http://www.w3.org/1999/xhtml">

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

<title></title>

<style type="text/css">

td, table

{

border: 1px solid #555;

border-collapse: collapse;

}

</style>

</head>

<body>

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

<telerik:RadScriptManager ID="RadManager" runat="server" />

<telerik:RadFormDecorator runat="server" ID="rfd1" DecoratedControls="All" Skin="Forest" />

<table cellpadding="2" cellspacing="0">

<tr>

<td>ASP TextBox</td>

<td><telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" Value="99.99" Type="Currency" LabelCssClass="MyLabel" />

</td>

</tr>

</table>

</form>

<script type="text/javascript">

var oldIsApplicableToUnifyWidth = Telerik.Web.UI.RadFormDecorator.prototype.isApplicableToUnifyWidth;

Telerik.Web.UI.RadFormDecorator.prototype.isApplicableToUnifyWidth = function (element) {

return oldIsApplicableToUnifyWidth.apply(this, arguments) && (!this.ancestorWithCssClass(element, "RadInput"));

};

Telerik.Web.UI.RadFormDecorator.prototype.ancestorWithCssClass = function (element, className) {

for (var parent = element.parentNode; parent.tagName; parent = element.parentNode)

if (Sys.UI.DomElement.containsCssClass(parent, className))

return parent;

return null;

};

</script>

</body>

</html>

Let us know if this works for you.
