Hello,

Can you please add the control ID to this error so the affected control can be easily identified?  Right now, if you have a page with multiple combo boxes, it is extremely time consuming to locate the one with the issue.

Thank you,
DJ

RadImageGallery is a great control and supports many image formats out of the box (JPEG, PNG, BMP, etc.)

However, it does not provide native support for HEIF.  HEIF is now the default format for most Apple devices (anything after iOS 11 update).

It would be great if RadImageGallery were updated to provide support for this format so that developers don't have to force image conversions of photos taken by Apple devices.

Hi,

currently the only way to set the translation for the "All" option that is created through the enabled "EnableAllOptionInPagerComboBox" property is to set the translation in the "RadGrid1_ItemDataBound" method, which is described here: Localization on RadGrid: Paging Option All

It's a workaround for a missing localisation. By setting the translation in the RadGrid1_ItemDataBound method the if-statement is being checked for every row processed, which is not good for performance.

Could you please make it possible to set the translation with a property and have the default value set in the resource file of the grid?

Thank you.

Scenario: need dynamically change header test on dropdown change, while retaining HeaderContext filter type icon

After conversation with support created this request

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 c.RadMenuItem._createChildControls (Telerik.Web.UI.WebRe...=:5300:49)

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

Sure you could do something really cool like a sketchpad, with a background image.

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.

It would be great if telerik can provide remove blank data rows on column which helps when dealing with huge data.

I am able to achieve the logic with below code.

  var grid = $find('<%= RadGrid_MeaInfo.ClientID %>');
            // MasterTable
            var masterTable = grid.get_masterTableView();
            // Items/Rows
            var dataItems = masterTable.get_dataItems();

            for (var i = 0; i < dataItems.length; i++) {
                var item = masterTable.getCellByColumnUniqueName(dataItems[i], "TriggerMan")
                debugger;
                if (item.innerHTML == "" || item.innerHTML == undefined) {
                    masterTable.hideItem(i);
                }
            }

I suggest to allow developers to customize the GridColumnGroup header. 

Custom column group headers should be a built-in feature of the RadGrid.

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;

		var isTableSelected = function (selected) {
			if (utils.isTag(selected, "table")) {
				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 = utils.isTag(selected, "table") ? selected : utils.getElementParentByTag(selected, "TABLE");
				var $table = $telerik.$(table);
				var data = $table.find("th,td");
				var firstCell = data.first().get(0);
				var lastCell = data.last().get(0);
				var firstFragment = fragments[0];
				var lastFragment = fragments[fragments.length - 1];
				var firstSelected = firstFragment.nodes[0];
				var lastSelected = lastFragment.nodes[lastFragment.nodes.length - 1];

				if ((firstSelected == firstCell || firstSelected == firstCell.firstChild || cmd.isMarker(firstCell.firstChild)) &&
					(lastSelected == lastCell || lastSelected == lastCell.lastChild)) {
					$table.find("." + cmd.getMarkersCssClass()).insertBefore(table);
					$telerik.$(table).remove();
					return;
				}
			}
					
			formatFragments.call(cmd, fragments);
		};

		// Fix for select and delete a table by the DomInspector in Chrome
		var Modules = $T.Editor.Modules;
		if (Modules && Modules.RadEditorDomInspector) {
			var removeSelectedElement = Modules.RadEditorDomInspector.prototype.removeSelectedElement;
