When you enable the control's keyboard navigation, using the arrow keys for navigation does not work when you use NVDA screen reader.

Recently when I was testing my ASP.Net application on different browsers, I found that in some of the browsers the controls did not work as expected.   These browsers were not in the list of compatible browsers mentioned at following URL:  http://www.telerik.com/aspnet-ajax/tech-sheets/browser-support

I then tried to come up with a method in JavaScript that would check if the current browser matched any one of the compatible browser name and browser version mentioned in above URL.  Then I could simply call this JavaScript method in the  page load event of master page and alert the user that the browser he or she is using is not compatible with the website.

It would be nice if such a method was there as part of RadControls library for ASP.Net AJAX. Such a method could be defined on client-side as well on the server-side.  It would  make life easier for a developer using RadControls, since users of the web site could be easily warned if they were using a browser that RadControls did not support.  Right now end users would just see the application behaving strangely when RadControls are rendered on an unsupported browser. 

The styles related to multipage are too broad and affect all child iframes, not just the one from multipage.

The second iframe must not inherit any styles

<telerik:RadMultiPage runat="server" SelectedIndex="1">
    <telerik:RadPageView runat="server" ContentUrl="http://www.telerik.com" >
    </telerik:RadPageView>
    <telerik:RadPageView runat="server">
        <div>
            <iframe src="http://www.telerik.com" ></iframe>
        </div>
    </telerik:RadPageView>
</telerik:RadMultiPage>

Using the web.config to enable lightweight or auto rendering for all controls, some of RadEditor dialogs (most of them are the Lite Dialogs) have visual issues and are impossible to be used. 

When the form element is offset, RadAutoCompleteBox popup is not properly positioned unlike the Combo / Dropdown counterparts.

Since we append all popups in the FORM element, the issue is only exhibited if FORM is not top level element, but is instead nested. The most obvious case is when you have Bootstrap structured page: .container > .row > .column.offset-3 > *form* > radautocompletebox.

For the time being you can use the following workaround:
CSS:
	<style>
		html span.RadButton_MetroTouch.rbToggleButton .rbText,
		html span.RadButton_BlackMetroTouch.rbToggleButton .rbText {
			padding: 0 25px;
		}
	</style>
ASPX:
			<telerik:RadButton ID="telerik:RadButton 1" runat="server" ToggleType="CheckBox" ButtonType="ToggleButton" Skin="MetroTouch"
				Text="Click">
			</telerik:RadButton>

There  is a JS error thrown in IE8 when the SlidingPanes are loaded. The error message is "Invalid procedure call or argument".

The functionality for strongly typed model-bound controls provides a significant boost in re-usability and ease of development. The documentation and support for this feature is, for all intents and purposes, non-existent.

Please provide demo applications for each data-control capable of model binding with full code showing how the make the feature work.

Capabilities should include common usages such as placing a drop-down list into a radgrid row, CRUD, filtering, and data-annotation and validation.

Performance and decreasing the footprint of JavaScript/CSS size of pages is very important for major websites. You all clearly know that as it was one of your goals with Lightweight rendering.

We would like documentation that shows the approximate file sizes for the Javascript and CSS files per control. We would also like to know the base libraries:

AnimationFramework.js - KB?
PopupScripts.js - KB?
TouchScrollExtender.js - KB?
ScrollingScripts.js
OData.js (why does this load if we aren't using OData?)
OverlayScript.js
NavigationScripts.js
etc

We would like more control over the loading of these and knowing what functionality dictates what scripts.

This would really help us evaluate whether to use a control or look for a lighter jQuery alternative as we are very concerned with file sizes and the loading time of our web pages.

Hi Telerik,

I've seen your new Theme Builder at http://themebuilder.telerik.com
This is wonderful tool for all developer and I love it.
So I have a feedback, can you create a Forum for everybody where we can share our Theme Builder in ASP.NET Ajax forum like Visual Style Builder forum's already exists.
And a library where the best Theme Builder was pulic by others developer.

I think this is good wat for the development of community Telerik

Thanks
