From Admin: Share in this thread the most impactful contrast issue here, sharing the control and its setup, the skin and the exact elements that are failing the contrast test.

Hi Team,

I'm using Telerik.Web.UI Version 2020.2.617

I have integrated it and added a reference in my web application, asked me to upgrade the version of Assemblies "System.Web.Extension.dll" and "System.Core.dll" has to be upgraded to version 4.0, I did that too, Now I'm getting an error while I'm running or doing build "The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)", Assembly it is referring to "System.Web.Script.Services", same error is coming for other attributes like "ScriptMethod, ScriptMethodAttribute"

For the Key word "this" it is throwing as below error

It is throwing an error for "System.Linq.Expressions"

Can anyone help me out on this how to resolve these bugs.

Regards

P L P Kumar

You can use the attached content to reproduce the problem in the Overview demo of the control.

I need a timeline AJAX component to "Visualize sequences of events in a user friendly manner" like this one in WPF : http://www.telerik.com/products/wpf/timeline.aspx

Do you plan to do that ?
Thanks

It will be nice to have a countDown control with all the client/server events and the suite skins, which will enable the developer to show a visitor with a timer to complete a task (like finsih a purchase with a guranteed price for few minutes) and call a web service when the timer got to zero, and show a message to the client (with integrated Notificatoin object) about the price (changed or staed the same etc.) and let the developer decide if he wants to start the timer again or not.

Thanks,
ilan.

How do I enable required field validation on a radcheckbox list item when it is part of a radwizard? I want to ensure that the user selects at least one item but when I hit the Next button to go to the next Wizard Step, it does not fire but proceeds to the next Wizard Step. Is this as designed?

Please provide assistance or some white paper article that can help.

I am using the "PostbackTriggers" property of the Upload control, as described on your web site article "How to Persist Uploaded Files".

This works well for the situation where I need a postback on a control, but that control is not a "submit" control.

The problem comes when I use one of the "submit" controls (listed in the PostbackTriggers property), but a server side validation error occurs, and the form data (including uploaded files) is NOT saved to the DB.  (This is a type of validation that can only be done on the server side.)  In that case, the upload control loses the uploaded file information.  Thus two questions:

1.   Is there a way on the server side to tell the control that an error has occurred, and to continue to persist the uploaded file information?

2.   Is there a way for the upload control to ALWAYS persist the uploaded file information until told on the server side that I have extracted the information I need from it?

Simple reproducible is attached to illustrate the problem.

A workaround may be replacing RadButtons that invokes such postbacks with regular buttons and using a form decorator

Alternatively, you can simply disable the handler URL encryption

You can also put the following in the global.asax file to prevent the version from rendering on the page markup
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
			System.Web.HttpContext.Current.Items["_!TelerikVersionStampRendered"] = true;
        }
or you can add the same line in a global Page_Load handler (e.g., in a base page class or in the master page your project uses)

We recently went to address a vulnerability finding in our application whereby a user could exploit a vulnerability in the Telerik.Web.UI version 2015.3.1111.45.  Unfortunately after applying the patched version of this assembly, when running the exploit by calling [site root]/Telerik.Web.UI.DialogHandler.aspx?DialogName=DocumentManager&renderMode=2&Skin=Default&Title=Document%20Manager&dpptn=&isRtl=false&dp={xxxxxxx}. The page returns a response of:

An error will occur when the Index equals the number of items in the collection

private static ClientOperation<T> Remove(ControlItemCollection items, int index)
{
	if (index < 0 || index > items.Count) // should be >= instead
		return null;
	var item = items[index];
	items.RemoveAt(index);

	var operation = new ClientOperation<T> {Item = (T) item, Type = ClientOperationType.Remove};

	return operation;
}

Please create high contrast theme for people with disabilities.

The best colors are yellow and black and there should be two combinations: yellow on black and black on yellow.

Please look at attachements for very good example.

The new Flat skin for KendoUI is excellent and it would be great to have the same skin available for ASP.NET AJAX applications. I can see it being especially useful when faced with migrating older apps that use the AJAX controls over to Kendo.

We could use a new calendar control that works differently than the scheduler, or any existing calendar control. 

Overview of features and how it would work:

• User selects a month, the calendar auto draws the month as a calendar view with options to set day of week as short, medium or full length.
• The calendar has an input field which can handle validation if needed. Validation example:
  • Only accept integers
  • In logic, if X = Whatever, then only allow input value of 1.

• Treat as an array so we could loop through the control and read each value for saving to database or to take action on from code.

• Example shown below. This is dynamically creating using tables and HTML. Not the nicest looking, and a pain to reuse anywhere. We could make use of this type of control in a lot of applications.

   

Please please please make the Material/Uniform/Bootstrap skins you've made for KendoUI/MVC for ASP.NET AJAX. These skins are so much more modern and clean than the ones available for ASP.NET, which look like they were designed 10 years ago.

The Metro and MetroTouch skins were a step forward for the ASP.NET AJAX library but the Metro is really small and the MetroTouch is really big. Somehow ASP.NET AJAX got the bad Metro skins and the Metro skin for KendoUI/MVC is the perfect size and beautiful. It doesn't need a "Touch" version because the one skin fits both bills.

Just compare the looks of the buttons between the ASP.NET AJAX Metro version and the KendoUI/MVC Metro version:

http://demos.telerik.com/aspnet-ajax/button/examples/overview/defaultcs.aspx?skin=Metro
http://demos.telerik.com/aspnet-ajax/button/examples/overview/defaultcs.aspx?skin=MetroTouch

http://demos.telerik.com/kendo-ui/button/index

Just like your own website is now flat and clean with nice buttons.

Please provide some new modern skins for ASP.NET AJAX as these controls are looking more outdated than ever, which bothers me because you continue to innovate on their functionality.

Make them look as great as they function!

Thanks.

As part of the Fall Creators update, Microsoft are releasing SDKs for their Fluent design system for UWP app design.

It would be great if Telerik could expand their skins to include controls designed to mimic the look and feel of the Fluent design including, where possible, Acrylic, Parallax, and Reveal.   I believe that light or dark themes will be standard on the Fluent design, but users will be able to incorporate the their accent colour preference.  So, at the least it would be great to have fluent light, and fluent dark skins with an easy method of similarly changing the accent colour.

Of course, not all of the functionality of UWP will be possible for ASP.NET AJAX, but since Fluent is likely to become the new standard for UWP app design, I believe that users will come to expect similar skins in their web-apps.

See https://docs.microsoft.com/en-us/windows/uwp/layout/design-and-ui-intro for more info.

Hi,It would be really handy to have an best practice identity provider UX 

There are  many ways to skin a cat, but it would be really handy to have a UI component much like you find in the ~/Account folder created by MS that all worked.
That had all the recovery logon by email working, having built in 2FA working.

The quick win would be to tell us how to write a 'Telerik Scenario' and where we can share them in Marketplace.telerik.com ?

Thanks

Hi,

Most of the telerik ASP.NET control examples while looking *really beautiful* are also hard to read / understand for beginning programmers like me :)

Why not add a truly minimalistic example per control that *only* shows the core functionality for each control?

grtz, 
Theo

Allow persisting of column widths
Allow persisting of what columns are displayed when a user selects them. (via EnableHeaderContextMenu) 

Thanks
