I generated a new project using the Telerik Blazor Template for server side.

In the _Host.cshtml file on line 27 it generates the following:

<a href class="reload">Reload</a>

Should be

<a href="" class="reload">Reload</a>

Have a nice day.

I cannot find an option of grid.SaveAsExcel() with blazor. 

I can export the grid using the grid toolbar but I want to export it without using the toolbar. I have a button group which has a row of buttons and I want to export the grid within the OnClick() event of the button group button. 

Could you please see if that is possible? Using .net core hosted blazor wasm

Thanks

Hello.

Is there a Timeline control for Blazor similar to this https://docs.telerik.com/devtools/wpf/controls/radtimeline/visual-structure ? If not, is there a plan for such control?

Thank you

Dear Telerik support team.

Today I updated my blazor app from 2.26 to 2.27 and encountered the following display issue for DDLs and numeric textboxes.
I currently use the local css file from the nuget package, but also tried to use the CDN for the latest version. Switching back from 2.27 to 2.26 on the CDN css perspective, makes the DDLs and numeric textboxes appear properly. Please see my screenshots attached.

Thanks in advance for your support.

Kind regards,
Thomas

Currently, any datepicker or dropdownlist works great in desktop, but when used in mobile, the dropdowns go off the bottom of the screen and don't fit the window correctly.  Could the dropdowns and datepicker type of the controls have a special "mobile mode" for smaller screen sizes to give a more native mobile feel?  Ex, the standard html select is handled much better by each device including wider options for fingers than the Telerik dropdownlist, but I'd like my site to be responsive for any screen size and not have to use two separate controls.

The https://nuget.telerik.com/nuget/ is erroring when trying to restore the packages, it's currently breaking our main pipeline.

I am getting a combination of these two errors below when instituting SignalR

   connection = new HubConnectionBuilder()
                                             .WithUrl(nm.ToAbsoluteUri("DataHub"))
                                             .Build();
                                            connection.On("ReceivedSyncRecord", this.OnReceiveSync);
                                            StateHasChanged();

                                            await connection.StartAsync();

Is it possible to show (modal confirmation) handle filtering before apply? Show pop-up modal, and when Confirm, start filtering, othewise cancel!!

The demos and examples for storing and retrieving GRID state uses the JavaScript localStorage.setItem and localStorage.getItem that work great.  As part of .NET 5 there's a Microsoft equivalent for accessing Local Storage using Microsoft.AspNetCore.Components.Server.ProtectedBrowserStorage.  I've found the behavior of these demos and examples will not work by simply replacing the JavaScript with .NET equivalents.  My experience is getting Circuit Handler exceptions that make these example not work.  

Although not a requirement since there's a JavaScript solution for local storage, I would like to recommend that since you partner closely with .NET team at Microsoft.  That your GRID development team test and provide examples with the Microsoft .NET 5 out-of-the-box local storage solution and resolve any incompatibilities for developers not wanting to use 1st party local storage solutions embedded within Microsoft Blazor.

ADMIN EDIT

I made a sample test and things seemed to work for me, so I made a public example, you can find it in this pull request until it gets merged. I'm also attaching it to this post, but for anyone seeing this after a time - the public repository linked above is a better place to look for this in case more updates and information have been added since the time of writing this.

Rendering the TelerikCalendar control produces HTML with ARIA roles like so:

• tbody - 'rowgroup'
  • tr - 'presentation' <--- this should be 'row'
    • td - 'gridcell'

Documentation: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/Gridcell_role

This seems small, but looks bad on accessibility reports, especially when a calendar has 42 'gridcells', The impact is significant when seen in summary.

Alternatively, or in addition, can ARIA roles be turned of for specific controls? In this case including role attributes in the markup is not actually necessary as the roles can be implied by the HTML tags. Including roles that are incorrect is more work for more confusion.

Currently when setting up a new Blazor app I need to go to the docs each time or look at a reference project to remember the resource paths for the CSS files. Additionally once you have a project if you are relying on a CDN but later update the NuGet package your app will be referencing the wrong css bundle unless you remembered to also update your layout.

Instead of having this as a magic string that is required in each project, it would be great if a new helper class could be introduced. As an example it might look something like:

public class TelerikResources
{
    public class Cdn
    {
        public class Default
        {
            public string Path = "";
        }

        public class Bootstrap
        {
            public string Path = "";
        }

        public class Material
        {
            public string Path = "";
        }
    }

    public class Local
    {
        public class Default
        {
            public string Path = "";
        }

        public class Bootstrap
        {
            public string Path = "";
        }

        public class Material
        {
            public string Path = "";
        }
    }
}

This would have the benefit that in the layout you might simply have:

<link href="@TelerikResources.Cdn.Bootstrap.Path" rel="stylesheet" />

This has a few benefits. It's easier to remember, easier to discover the other available prebuilt styles, and removes issues with pointing at the wrong path after updating library versions (assuming that you're using the Cdn rather than local resource).

Can we have the Image Gallery control like the ASPX AJAX, please? The slide show feature with various transitions is very useful. Thanks.

https://www.telerik.com/products/aspnet-ajax/image-gallery.aspx

I have a column grouped by groupname of producttype having values likes diesel,electric,gas,petrol but i want specific order in groups to appear like diesel,petrol,electric,gas 

Using  

Protected void onstateinithandler(gridstateeventargs <prdouctmodel> args)

{

gridstate <productmodel> statetobe = new gridstate <productmodel>()

{

GroupDescriptors = new list <groupdescriptor>()

{

new GroupDescriptor()

{ Member= "producttype",

Membertype =typeof (string)

}

},

Collapsedgroups =enumerable.range (0,4).tolist ()

};

args.gridstate = statetobe

}

Hi,

I have found some evidence of a bug which I believe add to the portrait of this issue which has already been reported but declined. Could you please have a look at my recent comments and report it to follow on it (so it remains active)?

Incremental Search A grid that can be searched incrementally as one types in the search box.

On-demand Sort It should have the ability to do a toggle between ascending and descending sort order when the user taps on a column header.

Pagination It should provide customizable pagination so only one page worth of data is fetched at any given time.

Did I describe the jQuery Datatable functionality? It is because it is so good and having the equivalent of its server-side implementation equivalent in Blazor will be awesome.

Implementation Thoughts The control sends a predefined model to an event bound function as parameter. The model has the information like requested page, column-sort request, letters the user typed into the search box etc. The function fetches data based on the model and the grid updates dynamically.
