On iOS 8 Safari the propagation of the "touch" event is not prevented, thus the element beneath the touched DropDownList item get touched as well.

Creating a lists with sub list, navigating to a parent list item and trying to add an sibling list item will cause the list to break. 

Under IE10 and 11 the CrossFade animation causes a random flickering. 

Creating a complex list nesting, sometime includes creating empty parent list item to include entire sub lists. In Chrome, Firefox and Opera pressing backspace in such items causes incorrect behavior and formatting.

This is actually a browser behavior, and it stems from the deletion of the BR tag inside the parent lists. Under IE, this is handled by native DOM operation that removes the entire parent list item and attaching its sub child's to the previous available one.

Hi  Telerik Support Team,

   This is suggestion,can find only one viewer to view all type files,pls look http://groupdocs.com/apps/viewer/live-demo,this viewer first generate png and js file using pdf2json.exe and mudra.exe form pdf file.
So at first other than pdf file using Aspose dll convert into pdf file,and then generate png and js file form converted pdf.
Currently we did above way to view all types of file in viewer,so if in teleriik  control ,it look more attractive way,like how ordinary button differe telerik button.
It just request/suggestion only,so not possible pls ignore it.

And compare 2 files interface possible in telerik control,in Notepad++ can do compare 2 files,it give different result .

With the support of insert list command in Track Changes functionality, users can insert lists. Although with enabled tracking users are not able to delete the list items, but only the text inside.

Steps to reproduce:
http://demos.telerik.com/aspnet-ajax/editor/examples/trackchanges/defaultcs.aspx

1. Insert a list with enabled TrackChanges
2. Start deleting list items

Expected: The whole list item is removed
Actual: Only the text inside the list item is deleted

System.Exception: 453.6 is not a valid value for Int32.

The encountered issue stems due to inheritance of CSS rules that select globally table elements. 

For the time being you can use the following CSS reset to improve the layout of the Editor's table elements:

.reLayoutWrapper, .reWrapper_corner, .reWrapper_center,
.reLeftVerticalSide, .reRightVerticalSide,
.reTlbVertical, .reToolCell, .reContentCell,
.reToolZone, .reBottomTable, .reEditorModesCell,
.reBottomZone, .reResizeCell {
	border: 0 none !important;
	padding: 0 !important;
}

.Telerik.reWrapper, .Telerik.RadEditor .reContentCell,
.Telerik.reColorPicker, .Telerik.reInsertTable,
.Telerik.reCustomLinks a:hover {
	border: 1px solid #828282 !important;
}

.reLeftVerticalSide, .reRightVerticalSide {
	padding: 1px !important;
}

Note that these CSS rules will affect RadEditor controls outside the RadGrid. If you need to modify only RadEditors inside RadGrid, use CssClass property and change the CSS selectors according the set class name.

Also, upon the used color you may need to change the border-color according to the Skin design.

In IE the command works fine.

In FF the command is always disabled.

In Chrome is always enabled, but using it do not affect the content.

If you need this tool to be always disabled under Chrome, you can use the following approach to disable the tool:

<telerik:RadEditor runat="server" ID="RadEditor1" OnClientSelectionChange="OnClientSelectionChange">
</telerik:RadEditor>

<script type="text/javascript">
	function OnClientSelectionChange(sender, args) {
		if ($telerik.isChrome) {
			setTimeout(function () {
				sender.get_toolAdapter().getToolByName("AbsolutePosition").set_enabled(false);
			},0)
		}
	}
</script>
