Hi

I don't understand the text in this yellow info box: "You can define a key for zooming only selection zooming is configured." Is there a word missing?

https://docs.telerik.com/blazor-ui/components/chart/pan-and-zoom/zoom#specifying-a-key-for-zooming

In my @code {

TelerikGrid<ClientViewDto>? MainGrid;

We'd like to track the community demand for using the Telerik Blazor components as Custom Elements.

Please share example common scenarios for such usage and list the components you want to register as Custom Elements to use in other SPA frameworks such as Angular or React.

On the NumericTextBox example here

If you put the NumericTextBox in edit mode and hold the up or down key on the keyboard, the value auto increments/decrements.

1/ Can you please replicate this when the mouse is held down when clicking the up down spinner buttons? Users don't want to always use keyboard for this function.

2/ Can you add an acceleration property, eg when mouse/key is held down it increments at rate n1 for first few seconds, then after time s1 it will increment at rate n2 for remaining time mouse/key held?

Hi,

Could it be possible to add an option to automatically add title property (containing text value) on every td?
We don't like 'multi-row' rows in a grid, so we use ellipsis with white-space no-wrap.. So it would be very useful to automatically add a title containing the text value of the cell (of course only for cells without a Template).
Otherwise we need to add a Template with a title to every column we already have, which is... 

Thanks in advance!

Greetings.

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;
    }

Currently we have 2 SelectionMode to select from in the ButtonGroup. I would like to have a third option that is a mix betwen Single and Multiple.

This third option should work like the Multiple mode but don't allow the user to deselect all ToggleButtons, like in the Single mode at least one button is allways selected. If the user clicks on the last selected Togglebutton he will not be able to deselect it.

Hello,

I am using the TelerikSkeleton component for Blazor and noticed the pulse and wave animations are not working. It seems animation also does not work in your examples here, while it works in Telerik REPL (that's where I could identify the issue)

For my application, I made my custom theme with ThemeBuilder and then imported it into my project as instructed. Going through the css file, I found where the bug is:

How it was:

.k-skeleton-pulse .k-skeleton {
    animation:k-skeleton-pulse 1.5s ease-in-out .5s infinite
}

After my changes:

.k-skeleton-pulse.k-skeleton {
     animation:k-skeleton-pulse 1.5s ease-in-out .5s infinite
}

The only thing I did was I removed the space between the two classes and now it works.

Note: I selected "WebAssembly" as application type, but I am actually using it for both a Razor class library and a .NET MAUI Blazor application.

I would like to disable the browser autocomplete. 

Applicable components:

ComboBox, AutoComplete, MultiSelect

I would really like to see a flyout control.  Something like the below

This would allow me to attach a popup dialog to a control instead of just doing a dialog at the center of the screen.

I need to track users activity per day like this, it is possible to do with any of the current components scheduler timeline? can you provide such option/component?

Need to include different colors in the bar. We were using google charts timeline but it is discontinued.

If you want to validate a form using FluentValidation right now you must rely on a third party validator like the ones suggested in the FluentValidation documentation.

We have noticed most of these libraries have not been updated in a long while despite issues being opened and pull requests pending:

• Blazored.FluentValidation - Last release: Dec 31, 2022

• Blazor-Validation - Last release: Jun 30, 2023

• Accelist.FluentValidation.Blazor - Last release: Nov 17, 2020

• vNext.BlazorComponents.FluentValidation - Last release: Sep 9, 2022

Also, we noticed that these libraries don't fully implement all the features that FluentValidation has to offer.

Ex: We wanted to use the Rulesets to validate fields partially when the input has changed (like maximum lenght or regexes) and then validate the more complex rules like "unique in DB" after the "submit" button of the form has been pressed but it seemed like it would run all validations ignoring the rulesets.

Other components libraries have already implemented FluentValidation natively, could Telerik consider implementing this aswell so we can stop relying on third party libraries and have a better implementation of the FluentValidation?

With
<TelerikNumericTextBox @bind-Value="myValue" Format="C" SelectOnFocus="true">
the content of the input is not selected upon focussing.  Without the Format="C" it is.

I have a ComboBox that gets data from a remote service, using virtualization. When the PageSize property is big enough (in my case 20), I have issues scrolling down. I'm trying to scroll but it removes the input text.

You can use your own demo examples to replicate this issue. To reproduce the issue, try the ComboBox - Virtualization, in Telerik REPL (Demo). 

Hi,

I am looking to use strongly-typed IDs in my project and it does not appear to be possible to achieve this with Telerik UI for Blazor. Instead, the popup does not go away on selection and the bound value does not update.

Note that this is not a request for binding to arbitrary complex types. I believe it would be sufficient to support value types that implement ToString / IParsable.

For example:

https://blazorrepl.telerik.com/QxvcQIPR55jFAGMF00

<h1>Hello, Telerik REPL for Blazor!</h1>
<h2>Selected Value: @SelectedValue</h2>

<TelerikDropDownList Data="@Data"
    @bind-Value="@SelectedValue"
    TextField="@nameof(SelectItem.DisplayName)"
    ValueField="@nameof(SelectItem.Value)"
    DefaultText="Select ...">
</TelerikDropDownList>

@code {
    public MyValue SelectedValue {get; set;}
    public SelectItem[] Data { get; } = new[] {
        new SelectItem(1),
        new SelectItem(2),
    };

    public readonly struct MyValue : System.IParsable<MyValue> {
        public int Value {get;}

        public MyValue(int value) {
            this.Value = value;
        }

        public override string ToString() {
            return Value.ToString();
        }

        public static MyValue Parse(string str, IFormatProvider provider) {
            return new(int.Parse(str, provider));
        }

        public static bool TryParse(string str, IFormatProvider provider, out MyValue value) {
            value = new(int.Parse(str, provider));
            return true;
        }
    }

    public class SelectItem {
        public SelectItem(int value) {
            Value = new(value);
            DisplayName = $"Item {value}";
        }

        public MyValue Value {get; set;}
        public string DisplayName {get; set;}
    }
}

Thanks,
Ben

There are some random bugs occurring after the latest version update (2.26.0)

- Styles evolving some buttons are broken
- Radio buttons are not working

Also, we're restoring the package on our automated CI/CD and the telerik nuget server does not have the previous versions available, we're are obligated to use the latest one, that's the main problem, you should have the previous version available, right now everything here is broken because of the latest version and we're creating a manual release to have the previous version in place

Hi,

Could you expose the Print Command of Blazor PDF Viewer? I would like to call it from within my code.

I am handling the SelecteditemsChanged event of the Grid and when an exception is thrown in its handler, the ErrorBoundarydoes not catch it.

For reference, I tried attaching the same handler to a click of a button and it is successfully caught by the ErrorBoundary in this case.
