Is this easy thing to integrate BootStrap with Telerik controls...can you please explain.. is it possible to change the telerik skin with bootstrap skin

Ticket # 541004

The shortcut TAB key provides correct behavior only for IE (  entities are added). UNder Firefox and Chrome the behavior is incorrect and not expected.

In FF - nothing is added to the content, moves the focus to the next HTML element.

In Chrome - a SPAN element is inserted.

A possible resolutions replacing the added shortcut for TAB key with the InsertTab command:

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

<script type="text/javascript">
	function OnClientLoad(editor, args) {
		var shortcutManager = editor.get_shortCutManager();

		if (shortcutManager.findShortCutByName("InsertTabMozilla")) {
			shortcutManager.removeShortCut("InsertTabMozilla");
			editor.addShortCut("InsertTab", "TAB");
		}
	}
</script>

Export to PDF  functionality to RadTreeView

When RenderMode is set to LightWeight and ToolbarMode is RibbonBar, a JavaScript error is thrown.

When the editor is loaded with a full HTML page editable document, which contains nested tables with images inside, selecting an image causes the Chrome browser to break. 

Possible workaround is disabling the resize widget of the tables and images in Chrome by incorporating this sample code:

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

<script type="text/javascript">
    Telerik.Web.UI.RadEditor.prototype._initializeResizableWidget =
        function myfunction() { };
</script>
