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>

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. 

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>

The DragAndDrop functionality of the RadAsyncUpload under Edge, works properly if DropZones property of the control is set.

An existing control looks like http://demos.devexpress.com/ASPxImageAndDataNavigationDemos/NewsControl/DataBinding.aspx
Where this control would allow you to express the UI of the aggregated feed data, where as the  feeds from RSS or  LinkedIn, YouTube etc can be sorted, grouped, stared or shared. 
So ideally feeds can be added at run time. Personal settings could be saved using existing tooling.
The ideal solution would allow the end user to customize their feeds.
Ideally it would degrade well onto a mobile  interface so you can flick thru all the feeds, flick to the left or right to dismiss or save. This is a bit more KendoUI

It would be nice to have a CardView type panel control.  This could simply be a dezoned raddock control that is optionally missing the header.  I am using some custom CSS for this now so that when the mouse moves over the div the shadow deepens to indicate selection.

It would be nice to adjust the elevation as well.

You can kind of get this now but taking a radwindow or a raddock but a dedicated control would be nice.

The CommandArgument value of RadButton is not available in the ClientClicking eventargs of RadButton. The get_commandName() method of the event arguments always returns null.


The issue is introduced in Q1 2016 release.

Steps to reproduce:
Run the following code and click the button.

    <script type="text/javascript">
        function btnEdit_Clicking(sender, eventArgs) {
            alert(eventArgs.get_commandArgument());
        }
    </script>
    <telerik:RadButton ID="RadButton2" AutoPostBack="false"
        runat="server" Text="Click Me"
        OnClientClicking="btnEdit_Clicking"
        CommandArgument="Name">
    </telerik:RadButton>

Steps to reproduce:

Use the following markup and click set html button:

<telerik:RadEditor ID="RadEditor1" runat="server" NewLineMode="Div">
<Content>
<div><span style="font-family: 'Courier New';">test</span></div>
<div><span style="font-family: 'Courier New';">&nbsp;</span></div>
<div><span style="font-family: 'Courier New';">test</span></div>
</Content>
</telerik:RadEditor>

<button type="button" onclick="getSetHtml();return false;">set html</button>

<script>
function getSetHtml() {
var editor = $find("RadEditor1");
var html = editor.get_html(true);
editor.set_html(html);
}
</script>

Actual: The white space character in the empty line is removed and the empty line is not rendered

Expected: The space is not removed and the new line is rendered

Workaround:

<script>
	(function ($E) {
		var utils = $E.Utils;
		Telerik.Web.UI.Editor.TrackerBase.prototype.removeZeroWidthNodes = 
			function () {
				var that = this,
					nodes = that.nodes,
					reZeroWidthChar = new RegExp("^[" + that._zeroWidthCharacter + "]+$");

				var nodeValuePairs = that.nodeValuePairs = [];
				for (var i = 0; i < nodes.length; i++) {
					var node = nodes[i];
					if (utils.isTextNode(node) && !that._isNodeRemoved(node)) {
						var nodeValue = node.nodeValue;
						if (reZeroWidthChar.test(nodeValue)) {
							nodeValuePairs.push({ node: node, value: node.nodeValue });
							var parentBlockElement = utils.getBlockParent(node);
							var isInEmptyBlockElement = parentBlockElement && utils.isNodeEmptyRecursive(parentBlockElement);
							node.nodeValue = isInEmptyBlockElement ? "\u00A0" : "";
						}
						else {
							that.removeFirstZeroWidthChar(node);
						}
					}
				}
			}
	})(Telerik.Web.UI.Editor);
</script>

This feature will allow users to set long footer's text and it will be displayed on a single line.

RadToolTipManager cannot find custom embedded skin, when a custom skin DLL is created with the Skins assembly builder (http://skinsassemblybuilder.telerik.com/).

Steps to reproduce:
1. Create a custom skin and wownload ZIP from Visual Style Builder (http://skinsassemblybuilder.telerik.com/)
2. Upload ZIP to Skins Assembly builder (http://skinsassemblybuilder.telerik.com/)
3. Create new project with Telerik template, turn off all options (like additional skins).
4. Add downloaded DLL as project reference.
5. Add to web.config:  <add key="Telerik.Skin" value="My_Skin" />
        <add key="Telerik.EnableEmbeddedSkins" value="true" />
        <add key="Telerik.EnableEmbeddedBaseStylesheet" value="true" />
        <add key="Telerik.Web.SkinsAssembly" value="My_Skin"/>
6. In Default.aspx, add
      <telerik:RadToolTipManager runat="server"></telerik:RadToolTipManager>

Result: an Internal Server Error is thrown:
Telerik.Web.UI.RadToolTipManager with ID='ctl03' was unable to find an embedded skin with the name 'My_Skin'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.
