Error: Uncaught TypeError: Cannot read property 'Polling' of undefined

When adding a link with a class name, the Unlink command cannot remove the formatting. 

Temporary solution is to clear anchor's classes programmatically via the ApplyClass command:

<telerik:RadEditor runat="server" ID="RadEditor1" OnClientCommandExecuting="OnClientCommandExecuting">
    <Content>
        <a href="http://www.telerik.com" class="my-class">link</a>
    </Content>
</telerik:RadEditor>

<script type="text/javascript">
    function OnClientCommandExecuting(sender, args) {
        var command = args.get_commandName && args.get_commandName();

        if (command === "Unlink") {
            var myArgs = new Telerik.Web.UI.EditorCommandEventArgs("ApplyClass", null, "");
            sender.fire("ApplyClass", myArgs);
        }
    }
</script>

The dragging clue element is shown before the actual dragging of the element in the Grid is initiated (immediately after the item is clicked). The problem is reproducible in Chrome.

Comment: The problem is not reproducible in the following TreeView demo:
http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/draganddropnodes/defaultcs.aspx

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/rows/drag-and-drop/defaultcs.aspx
2. Click over an item (just mouse-down, without moving the mouse nor full click)
Result: The dragging clue is shown without actual moving of the mouse pointer

Cursor is placed in the next available element (e.g., <p>) instead of being placed right after the tab space in the same paragraph.

Possible workaround is to implement a custom command to be triggered with tab key press:

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

<script>
    Telerik.Web.UI.Editor.CommandList["MyInsertTab"] = function (commandName, editor, oTool) {
        var utils = Telerik.Web.UI.Editor.Utils;
        var selecedElm = editor.getSelectedElement();
        var blockElm = utils.isBlockElement(selecedElm) ? selecedElm : utils.getBlockParent(selecedElm);
        var executeDefaultCommand = utils.isList(blockElm) ||
                                    utils.isTag(blockElm, "LI") ||
                                    utils.isTag(blockElm, "TD") ||
                                    utils.isTag(blockElm, "TH");

        if (executeDefaultCommand) {
            editor.fire("InsertTab");
        } else {
            editor.pasteHtml("<span>&nbsp;&nbsp;&nbsp;&nbsp;</span>&#8203;", commandName);
        }

    };

    function OnClientLoad(editor, args) {
        var shortcutManager = editor.get_shortCutManager();
        // Removing the InsertTabMozilla shortcut will 
        // assure that in Firefox the behavior will be consistent with IE.
        shortcutManager.removeShortCut("InsertTabMozilla");
        editor.addShortCut("MyInsertTab", "TAB");
    }
</script>

Workaround:
<telerik:RadEditor ID="radEditor1" runat="server" EnableTrackChanges="true"
	TrackChangesSettings-CanAcceptTrackChanges="true">
	<Content>
		<table>
			<tbody>
				<tr>
					<td>test</td>
					<td>test</td>
				</tr>
			</tbody>
		</table>
		<p>test paragraph</p>
	</Content>
</telerik:RadEditor>

<script type="text/javascript">
	(function ($T) {
		var prototype = $T.Editor.DefaultToolAdapter.prototype;
		var onContextMenu = prototype.onContextMenu;
		prototype.onContextMenu = function (e) {
			var editor = this.get_editor();
			if (!editor.get_enableTrackChanges()) {
				return onContextMenu.call(this, e);
			}
			if (!this._contextMenusEnabled || editor.get_mode() != $T.EditModes.Design) {
				return;
			}

			this.createContextMenus();
			var element = editor.getSelectedElement() || e.srcElement;
			var contextMenus = this._contextMenus;
			var contextElement = $T.Editor.Utils.getElementParentByCondition(element, function (node) {
				return !!contextMenus[node.nodeName];
			});
			var contextMenuId = contextElement ? contextElement.nodeName : "*";
			var parentTrackChangeEl = $T.Editor.TrackChangesUtils.findTrackChangesParentElement(element);
			if (parentTrackChangeEl) {
				if (parentTrackChangeEl.Type == $T.Editor.TrackChangesElementType.Comment)
					contextMenu = this.createContextMenuWithTrackChangeCommentItems(contextMenuId);
				else
					contextMenu = this.createContextMenuWithTrackChangeItems(contextMenuId);
			}
			else {
				contextMenu = this.createContextMenuWithTrackChangeDefaultItems(contextMenuId) || contextMenus[contextMenuId];
			}
			if (contextMenu) {
				contextMenu.set_eventObject(e);
				contextMenu.show();
			}
			return $telerik.cancelRawEvent(e);
		};
	})(Telerik.Web.UI)
</script>

The error is "Wrong Document". The dialog creates the table from different document instead of the document of the RadEditor's content area.

Here is the workaround:

<script type="text/javascript">
	Telerik.Web.UI.InsertTableLight.prototype.getModifiedTable = function(tableToModify){
		var rowCount = parseInt(this._rowsCount.value, 10);
		var colCount = parseInt(this._colsCount.value, 10);
		if (!tableToModify && !(isNaN(rowCount) || isNaN(colCount))) {
			tableToModify = this._editor.get_document().createElement("table");
			this._originalRowsCount = 0;
			this._originalColsCount = 0;
		}

		if (!tableToModify) return;

		var originalRowsCount = this._originalRowsCount;
		var originalColsCount = this._originalColsCount;

		if (rowCount > 0 && rowCount != originalRowsCount) {
			rowCount > originalRowsCount ? this.addRowsCols(tableToModify, originalRowsCount, rowCount, true) : this.removeRowsCols(tableToModify, originalRowsCount, rowCount, true);
		}
		if (colCount > 0 && colCount != originalColsCount) {
			colCount > originalColsCount ? this.addRowsCols(tableToModify, originalColsCount, colCount, false) : this.removeRowsCols(tableToModify, originalColsCount, colCount, false);
		}
		this._setAttribValue(tableToModify, "align", this._alignmentSelectorTable.getAlign());
		var oSpacing = parseInt(this._cellSpacing.value, 10);
		if (!isNaN(parseInt(oSpacing, 10))) this._setAttribValue(tableToModify, "cellSpacing", oSpacing >= 0 ? oSpacing : "", (oSpacing >= 0));

		var oPadding = parseInt(this._cellPadding.value, 10);
		if (!isNaN(parseInt(oPadding, 10))) this._setAttribValue(tableToModify, "cellPadding", oPadding >= 0 ? oPadding : "", (oPadding >= 0));

		var oBorderWidth = parseInt(this._borderWidth.value, 10);
		if (!isNaN(parseInt(oBorderWidth, 10))) this._setAttribValue(tableToModify, "border", oBorderWidth >= 0 ? oBorderWidth : "", (oBorderWidth >= 0));

		return tableToModify;
	}
</script>

Enabling Fluid behavior of RadEditor (Width="100%") causes the tools not to collapse with a smaller view-port. Also, there are some further visual glitches with the toolbar.

Solution 1: Add a CSS rule to expand the height of the tool-groups automatically.

    .<SkinName>.reToolbar {
                height:auto !important;
    }

Solution 2: Enable Lightweight rendering (or Auto).

    <telerik:RadEditor ID="RadEditor1" Skin="Silk" RenderMode="Lightweight" runat="server" Width="100%" >
    </telerik:RadEditor>

It is design limitation. The format is not not applied because the context menu is single for all columns, but each column can have different format. The DateInput inside the filter menu can not have multiple formats at the same time.

A rad calculator picker for asp.net textboxes similar to what you have in Silverlight.

When end-user changes the font-name and size of a single word in the content, pressing spacebar resets the formatting to its default state. 

Steps to reproduce:

    1. Go to http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx;
    2. Remove all content and add a simple sentence, e.g., "some text";
    3. Highlight "text";
    4. Change font-name and size;
    5. Put the cursor right after "text"
    6. Press spacebar (add white space)
    7. Type another word.

In Visual Studio 2015 Pro justmock generates this error error MSB6006: "vbc.exe" To function properly you need to uninstall VS2015 justmock.
