When the AriaSupport for the Grid is turned on, an aria-label is added to each column header automatically using the UniqueName of the column. The problem is - UniqueName doesn't support empty spaces - all "labels" must be single words or use Underscores - and the screen readers say "underscore."

So my column of "call_date" results in "Call underscore Date" - which is not useful for visually impaired people.

When the grid has a horizontal scroll bar displayed, we can't scroll the table horizontally using keyboard only.  If testing using the Siteimprove Accessibility Checker, we will get the issue "Scrollable element is not keyboard accessible".

The reason is that when the RadGrid is rendered, the horizontal scroll bar is render as a separate <div> out of the data table, and the horizontal scroll bar doesn’t have a tabindex, so there’s no way to put focus on it using keyboard.  Can you add tabindex="0" to the horizontal scroll bar?

Rendering and tabbing through the menus goes well BUT - the following was reported:

• With NVDA/Firefox, while the menu item names (File, Edit, View) are announced, but nothing is announced that lets me know that I can expand them to hear more. Usually the space and enter key are used to toggle menus, but neither of those do anything.
• With NVDA/Chrome, I get the same experience.
• With JAWS/Chrome, I hear some more info: when I’m on File, I hear File alt plus F (then Edit alt plus E, View alt plus V). It seems like the latter two of these open up the menu visually, but I’m not able to navigate to any of the items with my keyboard or hear them with my screen reader.

The BIG issue seems to be the lack of indication that a SubMenu exists - is this a known issue?  Am I not enabling something I should be?

Current RadMenu config:

  <telerik:RadMenu AriaSettings-Label="Manage a Business Menu" runat="server" ID="m" Width="100%" Skin="Simple" Flow="Horizontal" RenderMode="Lightweight"
                EnableAriaSupport="true" CausesValidation="false" EnableOverlay="false">
                <KeyboardNavigationSettings CommandKey="Alt" FocusKey="M" />
            </telerik:RadMenu>    

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

After conversation with support created this request

I want to be able to let a user choose "Landlords", "Tenants", "Owners" and search for a name. The data for the search box comes from different tables.

<asp:SqlDataSource ID="SqlDataSourceTenants" runat="server"

                           ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
                           SelectCommand="SELECT Id,TenantEntityName as EntityName FROM TenantEntities"></asp:SqlDataSource>
        <asp:SqlDataSource ID="SqlDataSourceLandlords" runat="server"
                           ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
                           SelectCommand="SELECT Id, LandlordEntityName as EntityName FROM LandlordEntities"></asp:SqlDataSource>
        <asp:SqlDataSource ID="SqlDataSourceOwners" runat="server"
                           ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
                           SelectCommand="SELECT Id,OwnerEntityName As EntityName FROM OwnerEntities"></asp:SqlDataSource> 

I would like to set the DatasourceId on the RadSearchBox to one of the above when the SearchContext changes. I have worked out how to get the selected searchcontext text via an Ajax Request.

     function OnClientLoad(sender, args) {
                    var context = sender.get_searchContext();
                    var $ = $telerik.$;
                    $(context).on({
                        "selectedIndexChanged": function (event) {
                            var searchbox = $find("<%=RadSearchBox1.ClientID%>");

                // this is the search context dropdown selectedIndexChanged event handler 
                            var ajaxManager = $find("<%=RadAjaxManager1.ClientID%>");
                            ajaxManager.ajaxRequest(context.get_selectedItem().get_text());
            }
        });
                }

I cannot work out how to change the datasource at runtime (I get datasource not found when I run the following code).

    Protected Sub RadAjaxManager1_OnAjaxRequest(sender As Object, e As AjaxRequestEventArgs)
        if not isnothing(radsearchbox1.datasource)
            select Case e.Argument
                Case "Tenants"
                    RadSearchBox1.DataSource = sqldatasourcetenants
                    RadSearchBox1.databind
                Case "Landlords"
                    RadSearchBox1.DataSource = sqldatasourcelandlords
                    RadSearchBox1.databind
                Case "Owners"
                    RadSearchBox1.DataSource = sqldatasourceowners
                    RadSearchBox1.databind
            End Select
        End If
    End Sub

In the OnSearch Event I just need to get the type of entity (which I could get from checking the Id of the bound datasource) and the Id of the entity:

Protected Sub RadSearchBox1_OnSearch(sender As Object, e As SearchBoxEventArgs)
        If e.DataItem IsNot Nothing Then
            Dim dataItem = DirectCast(e.DataItem, Dictionary(Of String, Object))
            Dim thisId As String = dataItem("Id").ToString()
            Dim thisEntityName As String = dataItem("EntityName").ToString()
            ' Lookup in database and redirect to the relevant data view / edit page
        End If
    End Sub

Surely this is a common request and deserves consideration?

Currently, the HighlightAppearance of the Series does not have a property that controls the InactiveOpacity:

• https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/series.highlight#serieshighlightinactiveopacity 

As a temporary workaround, this can be set through the options in the OnKendoWidgetInitializing event:

<script>
    function OnKendoWidgetInitializing(sender, args) {
        var series = args.series[0]
        series.highlight = series.highlight || {};
        series.highlight.inactiveOpacity = 0.2
    }
</script>
<telerik:RadHtmlChart ID="RadHtmlChart5" runat="server" BorderColor="Fuchsia" BorderStyle="Solid" BorderWidth="1px">
    <ClientEvents OnKendoWidgetInitializing="OnKendoWidgetInitializing" />
    <PlotArea>

        <Series>
            <telerik:PieSeries StartAngle="90">
                <%-- This is how it should be configured after the feature request --%>
                <%--<HighlightAppearance InactiveOpacity="0.2" />--%>

                <SeriesItems>
                    <telerik:PieSeriesItem Name="Slice1" Y="60"></telerik:PieSeriesItem>
                    <telerik:PieSeriesItem Name="Slice2" Y="40"></telerik:PieSeriesItem>
                </SeriesItems>
            </telerik:PieSeries>
        </Series>
    </PlotArea>
</telerik:RadHtmlChart>

I am reaching out in regards of an update we need to resolve a vulnerability in our system. I am not aware if my company has a license already but I was informed that we could get the hotfix by opening a ticket. Please let me know if there is another method to get the hotfix.

Contact email: xxxxx <- updated by Telerik admin

Response we got from TELERIK:

If you don't have an active license, you can reach out the Telerik support by opening a General Feedback ticket.

I suggest to allow developers to customize the GridColumnGroup header. 

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

Error message:

Possible workarounds from Admin: 

1) Use Lightweight render mode instead of Classic: https://docs.telerik.com/devtools/aspnet-ajax/controls/render-modes#setting-render-mode 

2) Disable temporarily the keyboard navigation of the control

3) Use the attached script and load it on the page: 

3.1) Using a RadScriptManager (adjust the file name and path to fit your application)

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    <Scripts>
        <telerik:RadScriptReference Path="fix.js" OutputPosition="End" />
    </Scripts>
</telerik:RadScriptManager>

3.2) In an inline script tag somewhere AFTER the ScriptManager(e.g. at the end of the <form> or <body> tag)

3.3) As a script reference - place it AFTER the script manager as 3.2) or use the defer="defer" attribute

<script defer="defer" src="fix.js"></script>

4) Submit a support ticket if you would prefer a custom Telerik.Web.UI.dll assembly with the issue resolved.

Under heavy load in a multithreaded environment, a concurrency issue can occur, related to System.Collections.Generic.Dictionary`2.Insert

This might lead to High CPU usage and might require an IIS restart.

Workaround:

• Use CDN for Telerik styles and scripts
  • https://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/custom-cdn-provider 
  • https://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/overview 

   

Regression introduced in R1 2021 SP1 results in an appearance glitch:

Perhaps a simple feature to permit high speed searches in RadSearch is to allow custom SQL Select strings in lieu of direct connect to a SQL Datasource (unless there is a way to accomplish the following in a SQL Datasource)

I have FreeText and text optimization configured/added in SQL Server.  This provides a tremendous speed boost for searching strings.  Therefore, somehow in the RadSearch box allow searches such as:

SELECT * FROM myTable WHERE contains(myTextIndexedColumn,'this is fast') 

SELECT * FROM myTable WHERE FreeText(myTextIndexedColumn,'this is so much faster!') 

While the Progress SASS ThemeBuilder - UI for ASP.NET AJAX is the only official online Web tool for creating custom Skins, some controls are not included.

We would like the ListView included in this process.

Current RadGrid only has headers/header templates for column headers. The only way to have headers for each row would be to manipulate the grid data and adding the header for each row into the grid data itself. And if we wanted to group the row headers is another round of manipulating the grid data and also manually merging the cells. Is it possible to have to have it as a feature of the RadGrid just like column groups and column headers to simplify the task? example of the final output ->
