ImageEditor keeps in the undo stack a reference to the last written text, but not last inserted one. 


Steps to reproduce:

1. Open
2. Click the add text tool and insert "One"
3. Click the add text tool and insert "Two"
4. Click the add text tool, write "Three" and cancel/close the dialog
5. Click "Undo"
6. Click "Redo"
Result: The last written "Three" string is inserted instead of the expected "Two"

Hello guys,


We've faced an issue with menu on several RAD controls when running on MacOS 10.14.x (Mojave) with FireFox 66.0.x (Quantum).

Using touchpad or mouse, when right clicking for context menu, it just flashed and doesn't stay open: it opens and then suddenly closes.

We are using Telerik Asp.Net Ajax version 2017.2.503.40 but it can be also replicated on your demo version:

Not sure if you can provide a fast workaround for this but I just wanted to let you know.

I've checked for some open cases before creating this thread and hope I didn't duplicate something. Please move/close it if necessary.

When looking at MetroTouch (and other) skin on FF, Edge and Chrome we see a little discrepance in the stepper bar, see attached.

This will be solved when altering css like so:

.RadWizard .rwzBreadCrumb .rwzLink::before {

    right: -0.5em;}

original value is:

right: -0.6em;

Would like to show column grouping for a few columns in the RaddGantt.


  • Planned Start and Planned End to be grouped under Planned
  • Actual Start and Actual End to be grouped under Actual
  • Financial Detail columns to be grouped under Task Financials

Also, would like to add to the query, how can I have the Gantt chart with the dates shown vertically as in the image attached. 
I don't want the Week or Month name coming in the grouping. Just dates in the timeline view.

When you open the insert Table dialog window in the RadEditor using the Silk skin the layout is messed up.  Button text is wrapping and the text 'px' is wrapped under the input field.

You can see this happening in the following demo page.

I have also attached a snip showing this.

It will be great to have a property in a raddock to automatically adjust its height/width to occupy the new space created when some other raddock in the layout is minimized. This will avoid the need for the user to adjust the height/width of the raddock which is still visible.

I have a big problem here. I have the following code and this code is launched in RadWindow as well:

<telerik:RadTabStrip runat="server" ID="RadTabStrip2" MultiPageID="RadMultiPage2" SelectedIndex="0">
        <telerik:RadTab Text="Add Response"></telerik:RadTab>
<telerik:RadMultiPage runat="server" ID="RadMultiPage2" SelectedIndex="0">
    <telerik:RadPageView runat="server" ID="RadPageView11">
            <telerik:RadEditor Width="100%" EditModes="Design" ID="reReqCom" runat="server"  ContentAreaCssFile="~/AppRoot/Xml/RadEditor/EditorContentArea.css"
                ToolsFile="~/AppRoot/Xml/RadEditor/BasicTools.xml" Skin="Material" />

The problem here is only using the iPhone (ioS), that the user is NOT able to select onto the RadEditor to begin typing. Seems to somehow block it out. I have stripped down to the basic code above and tested.

Can you tell us if this is a known issue?

Is there a workaround?

While JAWS will announce all of the items in the list as results are first read, it only says "Blank" as you arrow through the available options. Tabbing out of the control and back in, also does not read the selected content.

This is basically the opposite of what happens when ARIA support is turned off.

In that case, there is no announcement when results come back, but JAWS will read each individual item as you arrow through the available choices. Tabbing out of the control and back in still does not cause JAWS to read the selected item. 

This makes it seem like the ARIA version of the autocomplete box is missing either the appropriate ARIA roles or some other piece of rendered markup that is present in the non-ARIA-enabled version.


Ideally, when working with screen readers,  we would like to see something like the following behaviors:

* The number of items are announced when results are loaded, including empty results

* Each item is announced as the focus is moved through the list

* The selected item is announced when picked or whenever focus returns to the field.

      There is a cascading bug that we found in a scenario, where Telerik keeps adding default TabIndex of 0 which causes navigation problems, and removing it produces odd behavior with the JAWS Screen Reader in different browsers as mentioned under point 2. 

When the TabIndex is set :
1. The Radmenu adds tabindex=0 attribute to its rendered HTML and it causes some keyword navigation issues. 
Currently, the following navigation issues are noted when using Radmenu without removing the tab index attribute. The issues are present in keyboard and screen reader navigations.
• When tab key is pressed once the focus is on the entire menu and focus goes to the first menu item only on the second tab press. So tab has to be pressed twice to get focus on the first menu item. This is noted in all browsers.
• When using multiple Radmenus, the last item on the first Radmenu keeps highlighted after moving to the second menu. This issue is found in all browsers except IE11.

In order to fix the above:
The below javascript fix was applied. It removes the tabindex attribute from the menu using JS.

//Removes the tabindex attribute of RadMenu.
function RemoveRadMenuTabIndex() {
Taken from:

2. But now, when the JAWS screen reader is running:
That the tabindex gets removed via the above the JS Function, and hence the following problems occur when the TabIndex is not set :
- Using the screen reader with Edge browser, the submenu items are not showing (will not open at all) when using Radmenu with default render mode.
- The screen reader won't read the sub-menu items in any browser.
Tested with screen reader JAWS 2018 (demo/trial version runs well in 40-minute mode).

I have a problem with the deletecommand of the radgrid control (Telerik.Web.UI 2019.1.215.40).

This happens only in the latest release of Chrome.

I hope you can replicate this issue and eventually fix it.

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.

Trying to use a web testing tool (Selenium) and using xpath is not always working.  I was wondering if it would be possible to always add an ID property to controls, especially in drop downs etc. so that it can clicked properly.

When the DatePicker is with enabled WAI-ARIA support, Jaws reads "link 11" instead of the selected date "Monday, March 11, 2019".

We are using Telerik Ajax controls in our web site. We need a functionality where user can read a barcoded value using camera device or barcode image on a web page.

We found that Ajax Barcode control has only Barcode generator functionality.

Is there a way we can read barcode value on web site?

After upgrading the Telerik controls to v2019.1.115.45 we are seeing an issue with the RadEditor control. The issue is that the Toolbar formatting buttons like Bold, Underline etc. do not work for a particular scenario.


We have 2 tabs - Tab1 and Tab2. Tab1 is the default selected tab. Tab2 contains the RadEditor control. When the page loads, Tab1 is displayed/selected. We then go to Tab2 and click on the Toolbar to format the text. We click on buttons like Bold, Italic etc. but they do not work. Please refer to the files in the attached zip to see the issue.
<telerik:RadTabStrip runat="server" MultiPageID="MultiPage1" CausesValidation="false" SelectedIndex="1">
        <telerik:RadTab runat="server" Text="Tab1" Value="Tab1" PageViewID="Tab1" Selected="true" />
        <telerik:RadTab runat="server" Text="Tab2" Value="Tab2" PageViewID="Tab2" />
<telerik:RadMultiPage ID="MultiPage1" runat="server">
    <telerik:RadPageView ID="Tab1" runat="server" Selected="true">
        TAB 1 
    <telerik:RadPageView ID="Tab2" runat="server">
        <telerik:RadEditor Width="100%" ID="ERichTextBox1" Enabled="true" runat="server" ContentAreaMode="Div" NewLineMode="Br">

We could use a new calendar control that works differently than the scheduler, or any existing calendar control. 

Overview of features and how it would work:

  • User selects a month, the calendar auto draws the month as a calendar view with options to set day of week as short, medium or full length.
  • The calendar has an input field which can handle validation if needed. Validation example:
    • Only accept integers
    • In logic, if X = Whatever, then only allow input value of 1.

  • Treat as an array so we could loop through the control and read each value for saving to database or to take action on from code.

  • Example shown below. This is dynamically creating using tables and HTML. Not the nicest looking, and a pain to reuse anywhere. We could make use of this type of control in a lot of applications.
