Can't get RadAjaxManager onload when not localhost

Hello,

Let me try to explain the subject. I have a page with RadAjaxManager and need to get hold of it when application initially loads. I am doing it like that:

var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(this).ClientID %>");

problem is that it works fine when I open page in localhost, like http://localhost. However, when I change localhost to something else (like http://sameMachine), it can't get it and returns null.

Here is sample page:

<html lang="en">

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

<meta charset="utf-8" />

<title>Blah</title>

</head>

<body>

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

<telerik:RadScriptManager ID="ScriptManager" runat="server" EnablePageMethods="True"

EnableTheming="True">

</telerik:RadScriptManager>

<div id="Div1" class="page" runat="server">

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel" runat="server" Skin="Sitefinity" />

<telerik:RadAjaxManager ID="RadAjaxManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="testButton">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="testButton" UpdatePanelHeight="" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<asp:Button ID="testButton" runat="server" Text="Test Me" OnClientClick="TestMe('button');" />

</div>

<script type="text/javascript">

function TestMe(argument) {

var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(this).ClientID %>");

if (ajaxManager == null) {

alert('NULL. called by ' + argument);

}

else {

alert('Got it from ' + argument);

}

window.attachEvent("onload", function () {

// will work fine if run on localhost

TestMe('window.onload');

});

</script>

</form>

</body>

</html>

Please advise.

Thanks,
Nick

Image manager xhtml invalid attribute: complete="complete"

Hi,

When I use the Image Manager to insert an image into the contents of the RadEditor a link like <img alt="" style="width: 120px; height: 150px;" src="/CMS/Upload/Media/7038fa0c-61ec-46ae-a397-b899dc3b21e3.jpeg" complete="complete" complete="complete" /> is inserted (when I switch from the design view to the html view).
This is not xhtml compliant.
It is unclear to me why the attribute complete="complete" is inserted and why it's inserted twice.

Please inform me how to avoid such invalid attributes when inserting images.

Regards,

Mink

HowTo: custom resizable "select" button with rounded corners and hover styles

Hi,

Note: it's quick and dirty :)

I needed to customize the "Select" button's view to match UI, it should have had:
1)only button, no 'fake' file input, no file list, nothing, only immediate 1 file upload (to set current picture)
2)round corners
3)different style when hovered
4)resize to match inner text when site's language is changed

Note: when button is hovered in browsers that support Flash/Silverlight cursor doesn't change to 'pointer' type, but does in IE 64-bit.
I didn't investigate much, simple setting cursor: pointer !important; didn't do the trick (admins, any ideas?)

Ok, you will need to create 3 background png images (2 for button's left part (one with active image another passive) and 1 for the right part, the round corner). Note that I use one of left background images as background for ruUploadProgress span when there is an upload happening with a file name being uploaded.

.createContentPageAdditionalOptions .RadUpload

{

width:100px !important;

}

.RadUpload input

{

font-family: verdana !important;

}

.createContentPageAdditionalOptions .RadUpload input.ruFakeInput

{

display: none;

}

.RadUpload input.ruBrowse

{

background: url(/Images/btnLeftPartInactive.png) top left no-repeat !important;

width: auto !important;

line-height:21px;

height:23px;

text-align:left;

margin:0px 3px 0px 0px !important;

padding:0px 8px 3px 18px !important;

}

.createContentPageAdditionalOptions .RadUpload .ruInputs

{

text-align:center;

}

.RadUpload input.ruBrowse,

.createContentPageAdditionalOptions .RadUpload .ruUploadProgress,

.createContentPageAdditionalOptions .RadUpload .ruCancel,

.createContentPageAdditionalOptions .RadUpload .ruRemove

{

color:#fff !important;

}

.createContentPageAdditionalOptions .RadUpload .ruUploadProgress

{

background: url(/Images/btnLeftPartInactive.png) top left no-repeat !important;

margin:0px 3px 0px 0px !important;

height:23px;

overflow:hidden;

width:80px;

}

.RadUpload input.ruButtonHover

{

background: url(/Images/btnLeftPartActive.png) top left no-repeat !important;

color: #d14b35 !important;

}

.RadUpload .ruFileWrap

{

width: auto !important;

padding: 0px !important;

background: url(/Images/btnRightPart.png) top right no-repeat !important;

}

.RadUpload input.ruBrowse,

.createContentPageAdditionalOptions .RadUpload .ruCancel,

.createContentPageAdditionalOptions .RadUpload .ruRemove,

.RadUpload input.ruFileInput

{

cursor: pointer !important;

}

Note createContentPageAdditionalOptions class, I use it here cause I don't want to change the view of all asyncuploads I have, just particular one, next step, on the page where you have the control add following snippet:

var modules = Telerik.Web.UI.RadAsyncUpload.Modules;

if (modules && (modules.Silverlight.isAvailable() || modules.Flash.isAvailable())) {

$(".ruFileWrap").live("mouseover mouseout", function (event) {

$(this).children("input[class != 'ruFakeInput']").toggleClass("ruButtonHover");

});

}

This will enable native hovering to work when browser is using Flash/Silverlight object.

Finally my control:

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUploadImageForNavNode" AllowedFileExtensions="jpg,jpeg,png,gif"

CssClass="divToBeCentered" MaxFileSize="5242880" MultipleFileSelection="Disabled"

OnFileUploaded="RadAsyncUploadImageForNavNode_FileUploaded" EnableInlineProgress="false" Width="120px"

MaxFileInputsCount="1" OnClientFileUploaded="RadAsyncUploadImageForNavNode_OnClientFileUploaded"

Localization-Select="<%$ Resources:PGC, ProjectContentElement_UploadImage %>"

Localization-Cancel="<%$ Resources:PGC, General_Cancel %>"

Localization-Remove="<%$ Resources:PGC, General_Remove %>"

>

</telerik:RadAsyncUpload>

and JS it calls when upload completes:

function RadAsyncUploadImageForNavNode_OnClientFileUploaded(sender, args) {

$("#btnRefreshUploadedImageToCurrentProjectElementStub").click();

}

so that postback happens immediately and picture is set.

That's it, hopefully someone will find this usefull :)

P.S.: attached file has 4 views: default, hovered, uploading and default again (after upload)

2011 Q1 SP1 Features?

Is there a list of features that being added to the RibbonBar control in SP1? I checked the PITS system, but don't see anything there for the RibbonBar at all.

I have mentioned a couple of missing features/bugs in a previous issue which I was told were already on the to-do (Thanks! btw).

Is there by chance going to be a server side OnClick/OnCommand event available for a RibbonBarButton with CommandName and CommandArgument properties? How about a NavigateUrl for RibbonBarButton?

Thanks again! I really love this new control. We aren't planning on going live with it for a few months, but I at least want to make sure some of these features will eventually be added to the control.

DatePicker wrong Tooltip

Hi,

I’ve got a problem using the RadTooltipManager combined with RadDatePicker. I was able to fix the Problem on Firefox but not on IE and I don’t know what to do to get it work.

The problem is that the RadToolTip shows the wrong date as you can see on Screenshot 1.

After adding the Calendar-ClientEvents-OnCalendarViewChanged event to the DatePicker with the following JS-function

function OnCalendarViewChanged(sender, args) {

element = sender.get_element();

tooltipmanager = $find("<%=RadToolTipManager1.ClientID %>");

tooltipmanager.tooltipify(sender.get_element());

the problem is solved in FireFox as you can see on Screenshot 2. But in the IE the problem still exists…

I hope you are able to help me to fix this.

I'm using the Version 2010.3.1502.35

Show only the days of the current month in MonthView

Hey guys,
After looking thru the forums I can't seem to find anything to help me. I am wondering if it is possible to only show the actual month in the MonthView and NOT show the last/next few days of the previous/next month? I have two RadSchedule control on a page to give a 2 month view but the week of the next month is distracting to see twice ( example of month overlap ) Is there an easy way I can suppress the extra days?
Thanks,
Bryan Smouse

Problems with using CustomValidator for client-side validation

Hello, I'm trying to implement custom validation for my web page, but having problem. I want my ComboBox to be populated asynchronously from Web Service. So, here's the code of my page:

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

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

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

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

<head runat="server">

<title>

RadComboBox Sample Page

</title>

</head>

<body>

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

<script type="text/javascript">

function validatePerson(source, args) {

if ($find("<%=cbPersons.ClientID %>").get_value() > 0) {

args.IsValid = true;

} else {

args.IsValid = false;

}

</script>

<div>

<asp:ScriptManager runat="server" ID="scriptManager1"></asp:ScriptManager>

<table>

<tr>

<td>

<asp:Label runat="server" ID="lbl1">Select something</asp:Label>

</td>

<td>

<telerik:RadComboBox EmptyMessage="Select a person..." runat="server" ID="cbPersons" AllowCustomText="true" EnableLoadOnDemand="true">

<WebServiceSettings Method="GetPersons" Path="~/SampleWebService.asmx" />

</telerik:RadComboBox>

<asp:CustomValidator runat="server" ID="customValrPerson" ValidationGroup="Sample" ControlToValidate="cbPersons" ErrorMessage="Required" ClientValidationFunction="validatePerson"></asp:CustomValidator>

</td>

</tr>

<tr>

<td colspan="2">

<asp:LinkButton runat="server" ID="lnkSubmit" ValidationGroup="Sample" CausesValidation="true">Submit</asp:LinkButton>

</td>

</tr>

</table>

</div>

</form>

</body>

</html>

And here's the code of the web service that I use for generating ComboBox items:

<%@ WebService Language="C#" Class="SampleWebService" %>

using System;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.Web.Script.Services;

using Telerik.Web.UI;

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[ScriptService]

public class SampleWebService : System.Web.Services.WebService {

static string[] persons = { "Person Number 1", "Person Number 2", "Person Number 3", "Person Number 4", "Person Number 5" };

[WebMethod]

public RadComboBoxItemData[] GetPersons(RadComboBoxContext context)

{

RadComboBoxItemData[] result = null;

result = new RadComboBoxItemData[persons.Length];

for (int i = 0; i < persons.Length; i++)

{

result[i] = new RadComboBoxItemData { Text = persons[i], Value = i.ToString() };

}

return result;

}

So, I have number of problems.

1) When I load the page and click "Submit" link, validation doesn't happen and page gets post back. Obviously, that's wrong because ComboBox doesn't have any item selected.
2) When I select an item I see "Required" text. That happens because when validation function is called, this code:

$find("<%=cbPersons.ClientID %>").get_value()

returns "undefined". Sure, that's not how I expect things to work. When I click "Submit" link everything works properly.

P.S. It can seem that I would use RequiredFieldValidator in this example, but sometimes I will need to change the way selection is validated, so I would prefer to use CustomValidator for this.
