RadEditor Does Not Work in RadWindow

The RadWindow moves its contents in the DOM when it is opened - i.e. controls declared in its ContentTemplate are no longer in the same place in the markup where they were declared. This needs to be done in order to allow the popup element of the RadWindow to be shown above all other elements, so that it does not inherit any visibility restrictions from its parent elements (such as the CSS display property being set to none).

This, however, is not a scenario, which the RadEditor supports - it is a very complex control and needs to stay in the same place. Therefore when you place a RadEditor in the ContentTemplate of a RadWindow the buttons no longer function when you show the popup. This holds true for any scenario in which you move the RadEditor in the DOM.

There is an easy fix that causes the RadEditor to reattach its handlers and start functioning again - this is done by calling its onParentNodeChanged() method when you move it, which, in this case, is the OnClientShow event of the RadWindow:

<telerik:RadWindow RenderMode="Lightweight" runat="server" ID="RadWindowWithEditor" AutoSize="true" OnClientShow="fixEditor"
        <telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" Width="700px" Height="300px">
                Lorem ipsum dolor sit amet
<asp:Button ID="Button5" Text="open the RadWindow" runat="server" />
<script type="text/javascript">
    function fixEditor()
        $find("<%=RadEditor1.ClientID %>").onParentNodeChanged();

The following function uses jQuery to get all RadEditor objects in the ContentTemplate of the RadWindow in order to call their onParentNodeChanged() method. It is useful for scenarios when the RadEditor is inside a user control so you cannot get a direct reference to it via $find().

function fixEditor(sender, args) {
    $telerik.$(".RadEditor", sender.get_contentElement()).each(function (index, elem) {
        if (elem.control && elem.control.onParentNodeChanged) elem.control.onParentNodeChanged();

In some scenarios, just setting the ContentAreaMode from "Iframe" to "Div" might resolve the issue and make calling the onParentNodeChanged() method unnecessary.
