Questions on UI for ASP.NET AJAX Forum

I was able to successfully build a web form and using the ajax uploader control, upload files to an azure blob container (i.e. MyFiles-Blobs/hsc/so/file.txt). Now I would like the user to come back to the form and view the uploaded files and download the files at a later time. Can the uploaded control do this and if so is there an example I can use. Or is there a better way of doing this task? Thanks for the help with this request!

Sys.InvalidOperationException: Could not find UpdatePanel with ID '...'

Hi,
I have just upgraded an app from RadAjax Classic to the latest version for ASP .NET AJAX. I have been through the process of switching to the RadAjaxManagerProxy, adding ajax settings programatically in Page_Load instead of Page_Init etc.

Now most of my ajax updates are now working but some are not.

After certain updates the page fails to update and I get the following javascript error:

Error: [Exception... "'Sys.InvalidOperationException: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'someAjaxifiedControlPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

The particular control that this error message is complaining about is not part of the current update and is not currently visible. With RadAjax Classic this didn't matter, so I don't think this is the issue.

What causes this error?

Disabling "RowClick" for one column in a grid

I have set <ClientEvents OnRowClick="RowClick" /> to fire when a row is clicked. I have a Server-side checkbox on the row that I would like to exclude from this javascript event. Does anyone know if there is a way to do this and how?

Basically, I am trying to have a checkbox on the Grid row that when checked doesn't fire a server-side or client-side event. When I click on a button on the page, I'd like to cycle through the grid and get the items with a checkmark.

Thanks!

radeditor for foreign languages

I support a C#.net 2012 web form application. I am thinking of adding the radeditor to the application so users can edit letters like a word document on the web. There will be letters that are to be written in several languages like Spanish, Arabic, French, English and a few other languages. When the application is running a 'generic' template letter will be loaded and the user can edit the letter in the various languages. Almost all the users will only know English and Spanish and they do not know the other languages.

Thus my few questions are about the foreign languages are:

1. Can the radeditor handle the different languages? If so, do I need to change any radeditor settings to handle these different languages? If so, what would I need to change?

2. Can the radeditor format date/time that is applicable for the languages? If so, what would I need to do to format the date/time information?

Navigation Problem Error Message

Hi,

in my webapplication I use a RadMenu that contains some RadMenuItems.

The code is the following:

<asp:Content ID="Content2" ContentPlaceHolderID="FolderContent" runat="Server">

<telerik:RadMenu RenderMode="Lightweight" ID="RadMenu1" Flow="Vertical" CssClass="mainMenu" runat="server" ShowToggleHandle="true">

<Items>

<telerik:RadMenuItem Text="Leistungen" NavigateUrl="Views/Office/ServiceListView.aspx" />

<telerik:RadMenuItem Text="Warengruppen" NavigateUrl="" />

<telerik:RadMenuItem Text="Artikel" NavigateUrl="Views/Office/ArticleListView.aspx"></telerik:RadMenuItem>

When I click on MenuItem "Leistungen" the page ServiceListView.aspx in the folder Views/Office/ should be load in the MainContent and in the browser.

But it doesn't work.

I get the following error message:

System.Web.HttpException: "Vorangestellte .. können nicht zum Beenden auf oberster Verzeichnisebene verwendet werden."

How can I adjust the path without errors?

RadCalendar Localization Issue with CultureInfo

Hi,

We tried the examples given in the Telerik site for RadCalendar and implemented Localization for the same successfully. But, it works only for the Culture \ CultureInfo properties (like "en-US", "fr-FR") for both RadScheduler and RadCalendar. But, in our application we are using only "CurrentUICulture", which has the value of only neutral culture (like en, fr etc ...) . When this is assigned to the RadCalendar, we are getting the following error:

Message: Culture 'fr' is a neutral culture. It cannot be used in formatting and parsing and therefore cannot be set as the thread's current culture.
Stack trace:
at System.Globalization.

CultureInfo.CheckNeutral(CultureInfo culture)
   at System.Globalization.CultureInfo.get_DateTimeFormat()
   at Telerik.Web.UI.Scheduler.Views.Month.RendererBase.CreateNavigationPane(Control container)
   at Telerik.Web.UI.Scheduler.Views.Month.Renderer.GetContent()
   at Telerik.Web.UI.RadScheduler.CreateContent()
   at Telerik.Web.UI.RadScheduler.CreateChildControls(Boolean bindFromDataSource)
   at System.Web.UI.Control.EnsureChildControls()

   at System.Web.UI.Control.PreRenderRecursiveInternal()
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

But, as per the information given in the link below, the 'CultureInfo' property should also support the two letter ISO Language names like "en" or "fr" etc ..
http://www.telerik.com/help/aspnet-ajax/p_telerik_web_ui_radcalendar_cultureinfo.html

Can you please let us know a solution for this ? How can we assign the 'CurrentUICulture' (TwoLetterISOLanguage Name) value to the 'RadCalendar' control, which has only the 'CultureInfo' property ?

Thanks & Regards,
Karthik.
