When the ribbon bar is set to RibbonBarFloating, RibbonBarPageTop or RibbonBarShowOnFocus the menus cut off so you can't access menu items that would be displayed below bounds of the ribbon bar.

You can see this happening at:

I have also supplied a snip of the issue.

Steps to Reproduce:
1) bold a non tracked word
2) Append an "s" (or other letter) to the previous non tracked word
3) delete the space between the previous word and the bolded word

Actual: the tracking will delete the first letter of the bolded word

Expected: the space should be deleted

<telerik:RadEditor ID="RadEditor1" runat="server" EnableTrackChanges="true">
		<p>some plain text</p>
	(function ($, $E, undefined) {
		var utils = $E.Utils;
		utils.isInlineSpace = utils.isInlineSpace || function (node) {
			return utils.isTextNodeEmpty(node) && node.previousSibling && node.nextSibling &&
				!utils.isBlockElement(node.previousSibling) && !utils.isBlockElement(node.nextSibling);
		var isSignificantTextNode = function (node) {
			return utils.isTextNode(node) && (!utils.isTextNodeEmpty(node) || utils.isInlineSpace(node));
		var prototype = $E.PlainTextSelector.prototype;
		$E.PlainTextSelector = function (toLeft, topNode) {
			this.toLeft = toLeft;
			var condition = toLeft ?
								function (node, position) { return isSignificantTextNode(node) && (position > 0 && position <= node.nodeValue.length); } :
								function (node, position) { return isSignificantTextNode(node) && (position >= 0 && position < node.nodeValue.length); };

			this.traverser = new $E.DomTreeTraverser(condition, topNode);
		$E.PlainTextSelector.prototype = prototype;
	})($telerik.$, Telerik.Web.UI.Editor);

We are current experiencing a whitescreen with Telerik UI Controls for Ajax in chrome browser when the zoom level is less than 100. We observed a white screen instead of the rendered controls within main content area of our masterpage. The masterpage has several sections, header, left, mainconten, right and footer sections all divided by RadSplitter/RadPane controls. I attached a sample solution and screenshots of the observed issue.

Step to Reproduce:

- Open solution in Visual Studio

- Run choosing Chrome Browser

- Resize browser to 90%

- Reload the page


Page is rendered


White screen in the main content area

See attached screenshots

I am exporting all the appointments using the RadScheduler's Export Calendar functionality (RadScheduler.ExportToICalendar(apptCollection, true)). 

I have the scheduler working with both regular and recurring appointments in my project with RadScheduler along with different timezone for each of the appointments within the scheduler properly. 

However, when I export the same through the above API as an ICS file, I am seeing that the date time is always coming out as UTC on recurring events giving me the wrong results in Outlook.

I'm using couple of Rad Editor controls in my webpart and using ToolProviderID for performance optimization.
I'm initializing one rad editor toolbar from server side and using the same toolbar to provide other rad editors with their toolbar, Bascially I'm using ToolProviderID attribute to initialize other RadEditors, after doing this the Comments and Track Changes feature stop working although their options are selected in the toolbar.

<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" EnableTrackChanges="true" EnableComments="true">
    <TrackChangesSettings Author="AuthorName" CanAcceptTrackChanges="true" UserCssId="reU0" />
            <telerik:EditorTool Name="AcceptTrackChange" />
            <telerik:EditorTool Name="RejectTrackChange" />
            <telerik:EditorTool Name="AcceptAllTrackChanges" />
            <telerik:EditorTool Name="RejectAllTrackChanges" />
            <telerik:EditorTool Name="EnableTrackChangesOverride" />
<telerik:RadEditor ID="RadEditor2" runat="server" ToolProviderID="RadEditor1" EnableTrackChanges="true" EnableComments="true"></telerik:RadEditor>
<telerik:RadEditor ID="RadEditor3" runat="server" ToolProviderID="RadEditor1" EnableTrackChanges="true" EnableComments="true"></telerik:RadEditor>

url to test with JAWS -

When I use JAWS to read the combobox present on this demo it reads as follows - ComboBox readonly - Alice Mutton. To change the selection press the arrow keys.

Over here, why JAWS is reading "readonly". It's not readonly. It's making our screenreader blind users confusing.

I drilled down more into the problem and found that, the input element below has the aria-readonly=true set though the combobox is not readonly.
Here is the html generated for above combobox from telerik demo site -

<input name="ctl00$ContentPlaceholder1$RadComboBox2" class="rcbInput radPreventDecorate" id="ctl00_ContentPlaceholder1_RadComboBox2_Input" role="combobox" aria-busy="false" aria-disabled="false" aria-expanded="false" aria-haspopup="true" aria-readonly="true" aria-owns="ctl00_ContentPlaceholder1_RadComboBox2_listbox" aria-autocomplete="none" type="text" readonly="readonly" value="Alice Mutton" autocomplete="off">

I understand that this input control should be readonly so that aria users should not type and go haywire. But looks like to maintain the readonly=readonly property, telerik is generating aria-readonly=true for this _Input control and resulting this issue.

When you change this attribute aria-readonly="true" to aria-readonly="false", JAWS read it correctly as follows - ComboBox - Alice Mutton. To change the selection press the arrow keys.

When I try to replace a white space in RadEditor, it is able to replace the words at the first line. The second one and onwards are not able to replace.


1. Open 'Find And Replace' dialog.

2. Go to 'Replace' tab.

3. Enter a white space for 'Find' text box.

4. Enter any character or word for 'Replace With' text box.

5. Hit on 'Replace All' button.

Reproducible in content which contains table elements and in the live demo:
