The OnClientTextChange event is triggered inconsistently in RadComboBox.

Typing custom text in the following RadComboBox and pressing enter does not fire the event:

        <script lang="javascript" type="text/javascript">
            function OnClientTextChange(sender, eventArgs) {
                alert("You typed " + sender.get_text());

                <telerik:RadComboBoxItem Text="item1" Value="item1" />
                <telerik:RadComboBoxItem Text="item12" Value="item12" />
                <telerik:RadComboBoxItem Text="aaaa" Value="aaa" />
                <telerik:RadComboBoxItem Text="bbbb" Value="bbb" />
                <telerik:RadComboBoxItem Text="AAAA1" Value="AAAA1" />
                <telerik:RadComboBoxItem Text="bbbb1" Value="bbb1" />
                <telerik:RadComboBoxItem Text="item11" Value="item11" />

I have found a Cross-Site Scripting issue in the rich text editor, RadEditor. This is not in a body where user provides certain strings, rather it's in the text properties which gets sent along with the user input, such as font-style. The developers were able to follow the filtering mechanisms given in at https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/prevent-cross-site-scripting-(xss), but it provides protection for the inputs given in <textarea>, and for the properties values. Hence XSS is still possible


Steps for Reproduction:


1. Open up the text editor {{Screenshot 2020-09-23 at 12.08.51 PM.png}}

2. Input a string and change its font style.

3. Click on submit and intercept the request. {{Screenshot 2020-09-23 at 12.14.45 PM.png}}

4. Now we need to modify the request body for parameter of texteditor's ID. You may notice that the font-style is set and sent by using a <span>.


Change parameter 'RadEditor1's value with the following:


5. Submit and notice the 200 OK response. Now go to the text editor and notice that the string texttexttext can be seen. {{Screenshot 2020-09-23 at 12.24.18 PM.png}}

6. Put a mouse cursor on the string and notice that it gets changed to ioioioioioioioioo<domainCookies>.



Please let me know if given information doesn't suffice the abilities for reproduction.

Example demo: https://demos.telerik.com/aspnet-ajax/combobox/examples/overview/defaultcs.aspx

And here's what JAWS sees:

Note the extra unlabeled "Button" following every combo box. This is confusing to the reader. They have no way to know that it is associated with the preceding field.

Additionally, I've noted that when aria-support is turned on, this button becomes focusable. Tabindex="0" is added to the span inside the text box. We prefer the older functionality where the button was not a tab stop. Which is the same behavior you have when aria support is turned off. For reference, see your own aria demo:

Note that the tab key stops on the drop down arrow. (You can check the previously linked demo and see that the arrows in those boxes are not tab stops.)

If right-click the arrow and inspect, you'll find the following: 

<span id="ctl00_ContentPlaceholder1_RadComboBox2_Arrow" class="p-icon p-i-arrow-60-down" role="button" aria-controls="ctl00_ContentPlaceholder1_RadComboBox2_listbox" tabindex="0"></span>

Adding aria support should not change behavior, so we'd prefer the tab stop was removed.

In our own application, we have additional problems when the button is focused and activated with either the "space" or "enter" keys, it refocuses the field, but it does not actually open the drop down. I do not see that problem in your demo. However, if the arrow button was removed as a tab stop and from the INS+F5 dialog, this would not be a problem.

Please note that all of the above is in Chrome. 


Using the following code in the OnClientLoad event of the ComboBox:

  var _DropDown_OnClientLoad = function (sender, args) {
    var input = sender.get_inputDomElement();

    //Remove tabindex from down-arrow button. We never want to focus this button.
    $telerik.$(input).siblings("button").find("[role=button]").attr("tabindex", null);

    //hide the down-arrow button from screen readers. The entire combo box
    //should be considered a single control.
    $telerik.$(input).siblings("button").attr("aria-hidden", "true");

When setting client events in a RadTextBox and using an EmptyMessage, the EmptyMessage will trigger the event on page load.  This is true for a multiple TextMode but others are untested.

We are using List box item scroll into view to scroll to the item selected in the list box. However, the scroll is not working in the Chrome browser in a UHD touch screen laptop device.

RadCodeBLock and RadScriptBlock is not able to handle the server tags for all case scenarios, hence RadAjaxManager throws the exception mentioned in the title.

2. Navigate to the ASP.NET Spreadsheet Demo

3. Highlight a few cells

Expected Behavior:

The cursor changes to a thin cross-hair icon but it doesn't change in IE 11.

In Telerik version 2016.2.607.45, the RadGrid Excel Like Filtering Context Menu Style is Broken. The width and alignment is not 100%. When I drop the older Telerik.Web.UI dll and corresponding Skins dll in my project, the issue is gone. I have attached two images, one from the latest release, and one from the older version. You can see how the latest versions style breaks and does not show the menu correctly.

Make configuration wizards work even on high resolution screens with scaling. See attached screen shot.

As I'm using RadDatePicker in my Grid,

In RadGrid for the first time, the image beside the calendar control renders as expected.

As soon as I enter into "InLine" edit mode there would be 2 images rendered beside the control.

And after clicking on cancel there is no change in the image beside the control.

Also attached the screenshot for the same.

Scrolling by touching the white space between the tiles is possible.

If you disable selection scrolling can work as expected.

Note that for tablets the scrolling container must be an element outside of the tilelist.
A workaround that fixes the majority of the issues is available in the attached sample.

When multiple RadButtons (ButtonType="ToggleButton" ToggleType="Radio") are grouped through GroupName property, the server-side property checked doesn't take effect when the button which is to be checked is declared before the current checked button.

The workaround is to execute JavaScript from the server which sets the checked property. For example:


        string script = "function f(){$find(\"" + RadButton1.ClientID + "\").set_checked(true); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
        ScriptManager.RegisterStartupScript(this, this.GetType(), "key", script, true);

Wave Structure/Order is giving an error for RadSpell Control at "Not in Dictionary" label and Suggestions label. Hence our 508 testing is not passed. 

Please find the attachment for more details.

URL is: http://demos.telerik.com/aspnet-ajax/spell/examples/overview/defaultcs.aspx

Missing <h1> of Spell Check at the top of the dialog.

Not in Dictionary and Suggestions should not be headings they should be form labels.

Upgrading to UI for ASP.NET AJAX Q2 2015 (2015.2.729.45) sets requestLimits maxAllowedContentLength in web.config to 

<requestLimits maxAllowedContentLength="0" /> <!--8MB Max upload-->

resulting in errors like "PRM_ServerError" on postbacks.

With the use of the "UseStaticHeaders"-Parameter all ARIA-Tags are gone in the rendered RadGrid.
We need the support of WAI-ARIA in our application for our customer.
Dont using this Parameter is no option for us.
You are not telling this missing function in your documentation.

It becomes the operation of Chrome only.

after the new line, if you type continuously double-byte character string "あい",the input result was "い".
The correct answer is "あい".

For operation that does not occur in earlier versions, I think I've considered this release version of the bug, the cause can be identified?
