After the alert was confirmed, a Post Back is expected which does not happen due to a JavaScript exception: Cannot read property 'toString' of null

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

Workaround:
<telerik:RadEditor ID="RadEditor1" runat="server" EnableTrackChanges="true">
	<Content>
		<p>some plain text</p>
	</Content>
</telerik:RadEditor>
<script>
	(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);
</script>

Steps to reproduce:
1. Insert a table
2. Select 2-3 cells
3. Press delete

Actual: There is an nbsp between the cells

We are current experiencing a whitescreen with Telerik UI Controls for asp.net 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

Expected

Page is rendered

Observed

White screen in the main content area

See attached screenshots

i have a feature request

- Image map input

Based mapify,js sample below :

http://etiennemartin.ca/mapify/

I have use it before, storing areas and values in the databases, but the output is hyperlink.

I want it as asp.net input control that have selectedvalue property, i want server side value as the result. Maybe i can borrow hiddenfield or something. But it's wasting time.

Please, add image control input into your collection. It's very usefull i guess.

Using Firefox 64.0,  selecting an image doesn't appear the resizing handles which are located on each corner of the object

Load in IE this demo: http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

Enter in HTML mode - <p><a href="stm:b4f0c9ac-9a08-4c9f-8caf-39ccd4a83fc9" class="stm" contenteditable="false">Statement 111</a></p>

Switch to Design mode

Search for Statement with the Find and Replace dialog

The dialog won't be able to locate and highlight the link

Bootstrap popularity is growing each day, not just as a flexible grid system, but for it's skinning capabilieties as well. There are dozens of sites with both free and priced Bootstrap skins..
It would be nice to have a skin for rad controls wich maps straight to default Bootstrap classes.
So that just using the bootstrap skins (+ base Telerik controls skin) will also theme the rad controls and changing the Bootstrap themes of course changes the controls theming.

I guess that option to have a "straight" mapping of the rad controls to the bootstrap default classes so to be able to take advantage of bootstrap themes would be a great addition.

=====================
Updated by Telerik admin on 10.4.2017:
The status of this highly demanded feature has been updated to Declined, but you can find details what has been done during the years for satisfying this request:

Since the markup of the controls does not offer direct mapping for the Bootstrap v3 and v4 themes and classes, we introduced a new Bootstrap skin for the suite based on Bootstrap 3 component colors, metrics and appearance. This skin can be easily customized in the Theme Builder (http://themebuilder.telerik.com/aspnet-ajax) in terms of colors which allows you to create Bootstrap like appearance for Telerik Ajax components which matches the colors of your Bootstrap apps and components.

If you have any other requests for Bootstrap, don't hesitate to share them with us.

SlideView and PDFView are controls in the UI for Xamarin Forms 

When attempting to view the page in design view, here's what it looks like:

 

Here is the markup:

        <Items>
            <telerik:RadPanelItem runat="server" Expanded="True" PreventCollapse="true">

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" />
    <Tools>
        <telerik:EditorToolGroup>
            <telerik:EditorTool Name="AcceptTrackChange" />
            <telerik:EditorTool Name="RejectTrackChange" />
            <telerik:EditorTool Name="AcceptAllTrackChanges" />
            <telerik:EditorTool Name="RejectAllTrackChanges" />
            <telerik:EditorTool Name="EnableTrackChangesOverride" />
        </telerik:EditorToolGroup>
    </Tools>
</telerik:RadEditor>
<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>

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.

Step:

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: https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

<telerik:RadMaskedTextBox ID="RadMaskedTextBox2" Runat="server" Mask="<0..255>.<0..255>.<0..255>.<0..255>" ZeroPadNumericRanges="false" PromptChar="">  
</telerik:RadMaskedTextBox> 

Should render 192.168.1.1 instead of 192.168.__1.__1 

I would like to suggest a new control build from the same paradigm as the RadSocialShare.
The control should enable a website to provide an easy way to setup shared sign up / login from different providers on your website.

E.g. an easy way to let users sign up using their facebook account or Google account etc.

When the scripts are loaded through a script manager with enabled CDN and RadScriptManager.CombinedResource="Enabled", JS error will be thrown then the filtering button of the Grid is clicked.

Code to reproduce the problem:
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <CdnSettings TelerikCdn="Enabled" CombinedResource="Enabled" />
        </telerik:RadScriptManager>

        <telerik:RadGrid ID="UserDetailsGrid" runat="server" AllowFilteringByColumn="true" OnNeedDataSource="UserDetailsGrid_NeedDataSource"
            EnableHeaderContextMenu="true" EnableHeaderContextFilterMenu="true">
        </telerik:RadGrid>

C#:
        protected void UserDetailsGrid_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            var list = new[] {
                    new { FirstName = "F1", LastName ="L1"},
                    new { FirstName = "F2", LastName ="L2"},
                    new { FirstName = "F3", LastName ="L3"},
                    new { FirstName = "F4", LastName ="L4"}
                    }.ToList();
            UserDetailsGrid.DataSource = list;
        }
