Hi Telerik,

Just a heads-up - some of the demo pages are generating errors:

I have found this on:

https://demos.telerik.com/aspnet-ajax/errorpageresources.aspx?aspxerrorpath=/aspnet-ajax/grid/examples/overview/defaultcs.aspx

https://demos.telerik.com/aspnet-ajax/errorpageresources.aspx?aspxerrorpath=/aspnet-ajax/htmlchart/examples/overview/defaultcs.aspx

Dear staff I know this post

https://www.telerik.com/support/code-library/detecting-changes-to-the-radeditor

But in any case the component RadEditor have the method 'OnTextChanged' in the client side.

Probably, id it doesn't works, is better to remove it.

Thanks

Renato

Pasting plain text content from notepad or other text editor into the RadEditor control (design view) results in container HTML tags adding to the content and inline styles that make the text unreadable.

Content pasted:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut placerat orci nulla pellentesque dignissim enim sit. Diam quam nulla porttitor massa id neque. Ipsum suspendisse ultrices gravida dictum fusce ut. Sed odio morbi quis commodo odio aenean. Sed faucibus turpis in eu mi bibendum neque egestas congue. Sed pulvinar proin gravida hendrerit. Cras semper auctor neque vitae tempus. Nisi porta lorem mollis aliquam ut porttitor leo a diam. Quis vel eros donec ac odio tempor. Tellus in metus vulputate eu scelerisque felis imperdiet proin. Et ligula ullamcorper malesuada proin libero nunc consequat interdum. Neque viverra justo nec ultrices.

Result in RadEditor:

<div class="telerik_paste_container" style="border-width: 0px; position: absolute; overflow: hidden; margin: 0px; padding: 0px;">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

See accompanying screenshots.

While changing the value from RadCombox, meaning firing the SelectedIndexChanged, I am getting the below error.

When trying on localhost SelectedIndexChanged of RadCombobox is getting fired and rgrid_NeedDataSource of RadGrid is not fired but when deployed on IIS, the scenario is opposite, SelectedIndexChanged is not fired but rgrid_NeedDataSource is getting fired.

Please help.

Also another thing, I wanted to understand how to use licenses.licx file in our project for telerik dll version 2013.1.314.45?

The issue can be replicated with AutoCompleteBox demo: https://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultcs.aspx

Set the SingleLineEntries property to "Enabled", and add a new Entry to the AutoCompleteBox. At this point, the page will scroll up and as a result hiding the AutoCompleteBox.

I just installed the latest release (Telerik_UI_for_ASP.NET_AJAX_2023_1_314) and the program gives me an error.

This is the error :

Hello,

I'm facing JavaScript issues after enabling "Telerik.ScriptManager.EnableHandlerEncryption" on Web.config,

I've just followed Encrypt Telerik WebResource Querystring in order to hide the Telerik version.

After this the RadMenu breaks when i do a PostBack action (by pressing a button), the console outputs the same error when hovering a RadMenuItem and the submenus has stop being displayed.

The console error:

Uncaught TypeError: Cannot read properties of null (reading 'apply')
  at Type.callBaseMethod (Telerik.Web.UI.WebRe...=:6:7353)

  at HTMLDivElement.<anonymous> (Telerik.Web.UI.WebRe...=:6:307)

I've tested this error with version 2020.2.617.45 and 2022.3.913 but the same problem.

Looking in the forum i've found this post with a related issue also a reply has a reference to a private feedback and this last one seems to be the same or almost the same problem, so i've tried to follow the workaround on "global.asax" file and "Page_Load" on the master page without luck.

The steps i've follow:

• Enabling "Telerik.ScriptManager.EnableHandlerEncryption".
• Site seems working correctly.
• I press a RadButton inside a RadAjaxPane.
• Response from server is OK.
• Then i hover the cursor on RadMenuItems on RadMenu.
• Console starts to show the related error explaining above.
• RadMenu stops to present the submenus completely.

I'd like to have another way to workaround this in order to make RadMenu work properly again and keep Telerik version hidden.

Regards

Description:
'Selected' state is not defined for 'Pagination controls' in entire page.

Environment (OS, Application, Versions):
OS: Windows_11
Version: 21H2
OS Build: 22000.856
Browser: Microsoft Edge Version 105.0.1343.33 (Official build) (64-bit)
URL: https://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx
Screen Reader: NVDA(2022.2)

Repro Steps:
1. Open URL:https://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx page in Edge Browser.
2. Navigate to pagination controls present below "Book A Car' table under 'Overview'.
3. Open NVDA.
4. Navigate to 'Selected button' on pagination controls.
5. Observe an issue that 'Selected' state is not defined for 'Pagination controls'.

Actual Result:
'Selected' state is not defined for 'Pagination controls' in entire page.

Expected Result:
State 'Selected' should be defined on pagination controls. In this case, the expected role is {button or has a pop-up}. All components need a proper role attribute, ideally with semantics. In rare cases a role attribute should be added to give full context and information to assistive technology. Learn more by reading about when to use an aria role and the html/aria role mappings.

TEST ENVIRONMENT

Deleting of a table by delete or backspace key does not work when the selection contains only the table.
Steps to reproduce:
1. Set the following content
<p>test p1</p>
<table>
    <tbody>
        <tr>
            <td>test</td>
            <td>test</td>
        </tr>
    </tbody>
</table>
<p>test p2</p>

2. Select the table only and press delete or backspace key

Actual: Only the content has been deleted.
Expected: The table and its content to be deleted.

Workaround:
<telerik:RadEditor ID="RadEditor1" runat="server">
</telerik:RadEditor>

<script type="text/javascript">
	(function () {
		var $T = Telerik.Web.UI;
		var utils = $T.Editor.Utils;

				return true;
			}
			var table = utils.getElementParentByTag(selected, "TABLE");
			return table && !!utils.getElementParentByCondition(selected, function (current) {
				return utils.isAncestorOrSelf(table, current) && utils.isSingleChild(current);
			});
		};

		// Fix for delete table by delete or backspace key
		var formatFragments = $T.Editor.DeleteSelectionCommand.prototype.formatFragments;
		$T.Editor.DeleteSelectionCommand.prototype.formatFragments = function (fragments) {
			var cmd = this;
			var selected = cmd.get_editor().getSelectedElement();

			if (isTableSelected(selected) && fragments.length) {

				var $table = $telerik.$(table);
				var data = $table.find("th,td");
				var firstCell = data.first().get(0);

					$table.find("." + cmd.getMarkersCssClass()).insertBefore(table);
					$telerik.$(table).remove();
