RadEditor Find/Replace functionalities are not working in IE.


The following workaround could be used temporarily:
<script type="text/javascript">
            var $T = Telerik.Web.UI;
            Telerik.Web.UI.RadEditor.prototype.setActive = function () {
                if (this._emptyMessageContainer) this._hideEmptyMessage();
                if ($telerik.isIE && this.getSelection().isControl()) return;
                var curArea = this.get_mode() == $T.EditModes.Html ? this._getTextArea() : this.get_contentArea();
                if (curArea && curArea.setActive) curArea.setActive();
            };
            Telerik.Web.UI.RadEditor.prototype.setActiveIfElementIsNotInContent = function () {
                if (this._emptyMessageContainer) this._hideEmptyMessage();
                if ($telerik.isIE && this.getSelection().isControl()) return;
                var curArea = this.get_mode() == $T.EditModes.Html ? this._getTextArea() : this.get_contentArea();
                var activeElement = this.get_document().activeElement;
                var activeElementIsInContent = (activeElement && activeElement === curArea) || $.contains(curArea, activeElement);
                if (curArea && curArea.setActive && !activeElementIsInContent) {
                    curArea.setActive();
                }
            };

        </script>
