The long code lines in the QSF code viewer are very hard to read as the only way to get the horizontal scroll-bar is to reach the bottom of the page.

There is a black line that has appeared in my RadMenu.

The problem can be solved by adding a display: none in the following class:

.RadMenu .rmGroup:before, .RadMenu .rmMultiColumn:before, .RadMenu .rmScrollWrap>.rmHorizontal:before, .RadMenu .rmScrollWrap>.rmVertical:before

Native browser behavior is vendor specific and the above issue cannot be replicated with the latest version. Default browser in latest Android versions is Chrome and we recommend using it instead of the older native browser

Load in IE this demo: http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

Enter in HTML mode - <p><a href="stm:b4f0c9ac-9a08-4c9f-8caf-39ccd4a83fc9" class="stm" contenteditable="false">Statement 111</a></p>

Switch to Design mode

Search for Statement with the Find and Replace dialog

The dialog won't be able to locate and highlight the link

When a RadEditor or SPRadEditor in a custom WebPart for SharePoint 2013 is placed in an UpdatePanel or RadAjaxPanel it is not ajaxified and loses its content after a post back.

A workaround is to add the settings in the markup, for example:

<telerik:RadPersistenceManager runat="server" ID="RadPersistenceManager1">
	<PersistenceSettings>
		<telerik:PersistenceSetting ControlID="RadTileList1" />
	</PersistenceSettings>
</telerik:RadPersistenceManager>
<telerik:RadTileList runat="server" ID="RadTileList1">
</telerik:RadTileList>

The issue can be workarounded by calling preventDefault of the mousedown event when ComboBox item is clicked:
<telerik:RadScriptManager runat="server" />
<script>
	var onDocumentClick = Telerik.Web.UI.RadComboBox.prototype._onDocumentClick;
	Telerik.Web.UI.RadComboBox.prototype._onDocumentClick = function (e) {
		if (!e) e = event;

		var target = e.target || e.srcElement;

		while (target.nodeType !== 9) {
			if (!target.parentNode || target == this.get_element() || target == this.get_dropDownElement()) {
				e.preventDefault();
				return;
			}

			target = target.parentNode;
		}
		onDocumentClick.call(this, e);
	};
</script>

<telerik:RadComboBox ID="RadComboBox1" runat="server" RenderMode="Lightweight" OnClientBlur="OnClientBlur"
	CheckBoxes="true">
	<Items>
		<telerik:RadComboBoxItem Text="Item1" Value="1" />
		<telerik:RadComboBoxItem Text="Item2" Value="2" />
		<telerik:RadComboBoxItem Text="Item3" Value="3" />
		<telerik:RadComboBoxItem Text="Item4" Value="4" />
	</Items>
</telerik:RadComboBox>

<script>
	function OnClientBlur(sender, args) {
		console.log("Blur event");
	}
</script>

When the control is modal it should create a second iframe behind the modal background like it creates one behind the popup itself. This will allow the modal background to stay above heavy-weight objects in IE as well.

The sprite images for the RadButton are moved from the "Button" folder to the "Common" folder of the skins, but the Visual Style Builder searches the images in the Button folder.

The workaround is to extract the archive generated by the Visual Style Builder, move the sprites from the Common folder to the Button folder, archive the files again and import them in the Visual Style Builder. This allows you to edit them in the tool and after that you can download the skin and move the sprites back to the Common folder.

When a table is created through the table wizard and a background image is set to one of the cells, saving and closing the Editor in SP2010 causes the background image to be stripped.
