When many RadHtmlCharts are present on the page (especially if their animation is turned on) this will decrease the rendering performance of the browser, especially in older browsers that are generally slow. 

The ability to start rendering one chart only after the previous one finishes rendering will improve this initial load.

This can be used only for animations to provide a visual queue (i.e. only have effect when Transitions=true).

Provide a RadDateTime control that allows you to only pick the Day of the Week (Sunday - Saturday) rather than simply picking a Date or a Time.

when using spradgrid designer in SharePoint to retrieve data from sql tables the sql tables are ordered in a non sequence. this is really frustrating if you have a lot of tables. It would be great if you can order them by the table name.

Thanks   

ComboBox in native render mode does not add ID / NAME attributes to the select element.

I got the notice that Ajax Components 2013 Q3 was available, so I downloaded and installed it. Well, now every single project I have is broken! I have to go through all my projects and drag in the controls just to update the references,

This is shameful the way this breaks everything! Totally unprofessional the way the update is handled.

Visual style builder is not working properly in google chrome, doesnt reflect the changes that I m doing to create the style.

I love WebForms and the wealth in the Toolbar. 
I would like to write the payload of the web page in a webform and limit the round tripping with micro webservices, so there is no PostBack. Which means I can do more clientside in a KendoUI style. This would address the criticism of the bloat that comes with ViewState in webforms offering a leaner web page, but with all the advantages of the JavaScript tooling. 
For the most part a lot of this can be done already, would just prefer not to have any limitations in the controls that I can use for this. Just that there is such a driver now with the fashion of AngularJS/SPA applications suggesting that webforms cannot compete here.

We're using Telerik.ReportViewer.WebForms.ReportViewer for exporting to another files format but only exported to excel file I got error message below.

Error: Uncaught TypeError: Cannot read property 'Polling' of undefined

We have used Telerik controls for ASP.NET AJAX on our email verification ASP.Net application running on Windows server 2008 with IIS 8 in implementing a progress bar which shows the progress of emails verified. However, we have observed that when the application is run via the local host ( http://localhost/appplication.aspx) the progress bar always displays. However, when we run the application through the URL (http://111.222.333.444/application.aspx), the progress bar do not appear. Please kindly look into this. 

When i try to perform filter, browser shows Server time out or at some times it will work after 5 mins. I have almost 25k records in the grid. Selection is working fine. Can any one help?

Regarding: Client-side Binding, Programmatic Binding

Attempted to perform Client-side Binding to reduce sort and filtering network traffic, using this example http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx#qsf-demo-source as the basis of my work.

I could not get the server-side public static GetData method to get invoked (and stop on a source code break-point), regardless what I tried.

However, I would get a runtime error immediately if I comment out the GetData method entirely.

The example code on the Telerik website cannot be downloaded and relies on a SQL Server database (cannot find a way of examining working code -- e.g. hardcoded values that are returned from GetData static WebMethod).

Would really like to get client-side data-binding working, but am unsure how to proceed.

NOTE: I also tried enabling DataBinding > EnableCaching, but break-point on NeedDataSource still got hit when gridview data was sorted or filtered (and I want sorting and filtering to occur client-side).

RadGrid version 2013.1.220.40

Please could you make a RadToggleSwitch for ASP.NET AJAX? (Similar to the WinForms control)

an email text control.
a control like a text box but that filters out the invalid characters that cannot be used in an email address. This control could be separated in 3 parts:

part1@part2.part3

When the user hits the dot "." just before part3, a autocomplete feature can make it easier (faster) to select a frequently used prefex (like .com, .net, .org, etc...). This feature can be customized by the developer. The developer can turn it on or off. He can also make an own autocomplete list and eventually restrict to a list of suffixes.
Also when you want the user to type in an email address with a fix part 2 and part 3, the developer could customize it like this (e.g. when you want the user to enter only email addresses of @gmail.com, the developer can do this by design.

The three parts in the email address are required in order to have a valid email address.

As an extra feature the control can have a "IsValid()"-method that can be used by the developer to quickly check whether the email address is valid.

Server-side as well as client-side API make sense....
