Currently a page loaded through HTTPS will throw a warning that unsecure content is loaded if the IconUrl of the RadWindow is set with a relative path. This happens because the framework sets the URL without regard for the protocol. A workaround is to always use full urls (e.g.

If possible, RadWindow should check the protocol and fix the URL so that such warnings are not shown.

When you use the ApplyClass command to set CSS classes to selections in a paragraph element in the content of RadEditor, the CSS class is applied to the whole paragraph.

Release R2 2018
Possible Workaround:

Telerik.Web.UI.Grid.PositionDragElement = function(element, mouseEvent)
    var clientX = $telerik.isTouchDevice ? $telerik.getTouchEventLocation(mouseEvent).x : mouseEvent.clientX;
    var clientY = $telerik.isTouchDevice ? $telerik.getTouchEventLocation(mouseEvent).y : mouseEvent.clientY; = clientY + $telerik.getDocumentElementScrollTop() + 10 + "px"; = clientX + $telerik.getDocumentElementScrollLeft() + 10 + "px";

	if ($telerik.isOpera || $telerik.isTouchDevice)
	{ = parseInt(, 10) - document.body.scrollTop + "px";

Under IE, when two tables are placed next to each other, the Table Properties may cause the one to appear nested inside.

Currently, this can be workarounded only by assuring that there is some element between them - <br>, <p>, <div>, <span> etc.

When a partially copied table is pasted into the Editor in Chrome, it is pasted wrapped in the folloing div, making it not visible:

<div class="telerik_paste_container" style="border-width: 0px; position: absolute; overflow: hidden; margin: 0px; padding: 0px; left: 3px; top: 215px; width: 1px; height: 1px;">

Steps to reproduce:
1. Open
2. Clear the contents of the editor
3. Insert a table (any configuration of rows and columns) 
4. Go to a new line
5. Type a word on the new line
6. Select the word and a partial amount of the inserted table
7. Copy
8. Paste
9. Navigate to the HTML browser of the editor
10. Observe the "telerik_paste_container" still wrapping the pasted content

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

<script type="text/javascript">
	var editorPrototype = Telerik.Web.UI.RadEditor.prototype;
	var onAfterPaste = editorPrototype._onAfterPaste;
	editorPrototype._onAfterPaste = function (range, tmpPasteContainer) {
		try {, range, tmpPasteContainer);
		} catch (e) { }
