Just Moving from Ajax UI to Blazor
Used the search box a lot - multi-columns, had first match as typed toward an item,filtering, a click return the item selected
Wonderful
please can we have a blazor version?

We use QueryableExtensions.ToDataSourceResultmethod to load some data in our component. And at some moment we need to cancel data loading. But ToDataSourceResult method doesn’t support CancellationToken. So we are forced to use a workaround and just ignore the task's result. But task is still executing and causing the performance hit…
It would be great if you implemented support for this feature!
Further to issue reported in https://feedback.telerik.com/blazor/1545177-selected-items-are-not-preserved-when-loading-the-state-when-the-component-is-bound-to-expandoobjects wrt Expando Object, the column menu reset also does not work when grid is bound to Expando Object

Hello,
We are looking to port an angularjs web application to Blazor and I didn't see the diagram component similar to the one found in Kendo UI. It would be nice to see a viso-like component in UI for Blazor.
Thank you.
Hi
Passwords are not yet supported. There is a DataAnotations Datatype for that. So technically this is possible and should not be a big deal. Almost all apps have a password entry somewhere.
Example:
class LoginModel
{
[Required]
[Display(Name = "User Name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
}
Annoying because then you have to do the form fields all manually because of the password.
Thanks for considering.
Best regards, Michael
Hi. VS 2022 version 17.2.4, C#, Windows 11
I thought I'd have a look at blazor and selected the Telerik version in the new projects window and ran through the wizard.
I selected the dashboard look, .net 6, teleric UI for blazor 3.4.0 (Dev) and to enable localization, which is what I assume to be the cause of the following error message. There were no other hints and as I've never tried blazor or telerik for
blazor I don't know if there's anything missing from the solution. If I ran another wizard without localization there was no error.
An error occurred while running the wizard.
Error executing custom action Telerik.Blazor.VSX.Actions.CopyBlazorLocalizationResourcesAction: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

My license doesn't include support so this is the only way I could reach out to you. On this page, the line
.Read(r ==> rshould have => instead of ==>. When I pasted this into visual studio, it was giving me completely unrelated error and took me a bit to figure out what was wrong. Please fix the typo.
My team is currently using animation containers as menu popups in our web app, which will need to work on both desktop and mobile devices in a web browser. For the mobile layout, I would like to be able to open animation containers via swipe gestures. I understand that animation containers are not strictly menus, however, I would love to see swipe action support in Telerik UI for Blazor, and then be able to bind that action to an animation container.
The only framework I have found by way of example is https://onsen.io/. Please observe how it is possible to open a panel by swiping close to the edge of the sample device on their homepage.
This feature would make it much easier to build dynamic web apps that perform well on desktop and feel native on mobile devices as well.
Thank you,
David
I upgraded my Blazor UI package to 3.3.0 to try and get rid of the multiple tbody issue with adding a table. Now there is an even weirder problem. Adding a table with two columns via setting the Editor's value in the code block is causing several table cells to get inserted in between and around the desired ones.
This is my long html string:

This is the result:
At this point I am having to downgrade to 3.2.0 in order for it to look anything near what I need it to.
Here is my modal with the Editor component.

In the example below, the home icon is displayed correctly but the two with underscores are not. Moving the span outside the drawer does display correctly.

Hi good morning. I am implementing a FileManager control, but by business logic only certain users have permission to rename files. So in the onEdit method I validate the permission and if it doesn't have it I send a DialogFactory and after that I send an args.IsCancelled = true. And at the end of the event if I click on another item (file) inside the folder. throw an exception:
public async Task OnEdit(FileManagerEditEventArgs args)
{
Dialogs.AlertAsync(message, "FileManager");
args.IsCancelled = true;
}

We're a paying customer for the Blazor software components under AVEVA.
We need to do a substantial amount of custom real-time drawing on top of a Blazor based map control using a layer rendered on top of the Tile Layer. The currently supported Map layers are somewhat specific to smaller map indicators and static overlays.
Our rendering subsystem doing this drawing will be using SkiaSharp/Skia on WebAssembly, drawing on a Skiasharp canvas in the browser (this already works). I'm assuming behind the scenes the Map is drawing with a standard HTML canvas.
I believe we need a solution which resembles the following:
- The Image is a layer rendered on top of the map viewport (as opposed to the entire map canvas)
- The Image layer can know the size of the ViewPort so it can create an identical size image (or perhaps this is handled automatically by the Map control)
- The Image layer can be re-rendered as often as the customer code desires (we're showing realtime data on top of maps, so we will want to re-render the Image layer say every 250ms.
- When the map viewport changes (pan, zoom, etc.), events are fired so the Image layer customer code can re-render the image based on the new viewport coordinates and zoom level.
- Click events are passed through the Image Layer for processing.
Since we're using a different rendering technology than the underlying map control, my assumption is the best way to keep this simple is our code draws to a SkiaSharp canvas then converts that to PNG/BMP/whatever so that can be injected into the Image layer for rendering.
It would be expected that every pan/zoom/viewport change causes an entire re-rendering of the Image layer.
Hey Telerik Team,
we'd like to have a configurable line width and also color for the dependencies for the Gantt Diagram, configurable e.g.:
We're using the Gantt quite heavily and sometimes it's hard to mouse-point the exact pixel with that dependency line ;)
Thanks!
Hi Telerik Team,
it would be awesome to have a setting for adding a corner radius the dependency line, so the Gantt gets an additional visual improvement.
Example:
Could be added to the <GanttDependencies> Child-Element of <GanttDependenciesSettings>.
Thanks
Hi I have noticed that if the dropdown for an enum cannot wordwrap the item then the styling is broken, see the following the screenshot:
As you can see IN_PROGRESS is so long that it exceeds the column width and creates empty space above.
To me it appears as though an attempt to try to wordwrap the IN_PROGRESS but IN_PROGRESS has no applicable breaks in it.
Thanks,
Daniel
Hi,
I had to figure this out myself for the ComboBoxSettings because there is no documentation for this.
The MinWidth works from the Combobox width or greater extending the size of the popup and
MaxWidth only creates a popup width of the Combobox only.
Please document this feature and how to use it. And, is this intentional because it wasn't intuitive for me to figure out.
I created a REPL for you to test this out for yourself.
Hi.
I'd like to request the ability to use a TimeSpanPicker component in Blazor.
For example, see https://www.telerik.com/maui-ui/timespanpicker
Thank you.
