Currently, the TelerikChartBreadcrumb does not allow specifying how the Breadcrumb items are visualized when their total width exceeds the width of the component.

A possible alternative to achieve the same result is to override the default theme styles with the following CSS rule:

.k-breadcrumb-container {
    flex-flow: row wrap;
}

Here is a REPL example to see the result of the above CSS approach - https://blazorrepl.telerik.com/GTOyPYbG23PugZBQ36

We have forms that starts with single text box input, all other inputs are either hidden or disabled. Based on the value of that input we load additional data from the server, show/enable the rest of the inputs and move the focus to the next unput. We react to the value in that first input either when the Enter key is pressed, or when the input loses focus e.g. tab-out of the input or click/tap on another input. One or the other but never both. This scenario should be handled by the OnChange event. However, the OnChange event fires twice, when the enter key is pressed and again when the text box loses focus. This results in double data retrieval (takes twice the time), screen flicker and creates unpleasant user experience.

The recommended workaround is to add second variable to track if the input actually changed and ignore consequent events for the same value. This has it’s own caveat. If for any reason the user wants to retrieve the related data from server again e.g. he was notified it has changed, then he cannot use the OnChange event anymore because the value hasn’t changed and the event will be ignored. So the user has to change the value twice.

 We found a second workaround, see code below. Blur the text box on enter and handle only the on OnBlur event to process the value. This way we can process the value repeatedly, the user presses enter or tab-out, then focus back on the same input and hit enter or tab-out and repeat as many times as desired.

 We propose OnEnter event to be added to the text box so we don’t have to handle @onkeypress on outer <div>. The <div> events are also not synchronized with the DebounceDelay parameter of the text box. We have to either set the DebounceDelay to 0 or introduce delay in the KeyHandler method. The text box has OnBlur event already but surprisingly there is no OnEnter event.

We also proposed BlurAsync() method that will eliminate the need to create the javascript function and invoke JSRuntime.

 <<< javascript function >>>
function blurInput(inputId) {
    const textField = document.getElementById(inputId);
    if (textField) {
        textField.blur();
    }
}

<<< Blazor >>>
@page "/" 
@inject IJSRuntime JSRuntime

<PageTitle>Home</PageTitle>

<div @onkeydown="@(async (args) => await KeyHandler(args))">
    <TelerikTextBox id="txt1" Width="20rem" Placeholder="Pallet" DebounceDelay="0" @bind-Value="@_textInput" OnBlur="@OnInputBlur" />
</div>
<div>
    <TelerikTextBox @ref="_txtRef" Width="20rem" Placeholder="Pallet" />
</div>

@code
{
    private string? _textInput;
    private TelerikTextBox _txtRef = null!;

    private async Task KeyHandler(KeyboardEventArgs e)
    {
        if (e.Key == "Enter")
        {
            await JSRuntime.InvokeVoidAsync("blurInput", "txt1");
        }
    }

    private async Task OnInputBlur()
    {
        Console.WriteLine($"Bound variable: {_textInput}");
        await _txtRef.FocusAsync();
    }
}

}

Like https://docs.telerik.com/blazor-ui/components/combobox/custom-value and https://www.telerik.com/kendo-angular-ui/components/dropdowns/multiselect/custom-values/ so the user can input tags on their own without them being in the app data source.

ADMIN EDIT

The following sample may be useful in implementing this in the meantime: https://github.com/telerik/blazor-ui/tree/master/multiselect/add-new-item

Trying to upload a large file from a mobile device breaks the component.
Step to reproduce:

1. Open this REPL example on a mobile device
2. Click the "Load Data" button.

The issue can be reproduced only in version 8.0.0

Rebinding the PDF Viewer multiple times leads to an ever increasing memory usage, which can ultimately cause a browser crash.

The issue started with Telerik UI for Blazor version 8.0.0 and does not occur in 7.1.0.

Please consider altering or providing configuration for how DateTime values are formatted in filter expressions generated by ToDataSourceRequest(). Currently, the format includes full precision (e.g., 2025-04-04T00:00:00.0000000), which causes issues when passed to Entity Framework Core with SQL Server, as SQL Server expects precision up to milliseconds (.fff), not ticks (.fffffff).

Why This Is a Problem

• When passing filter expressions from ToDataSourceRequest() directly into a LINQ-to-EF query, the resulting SQL query fails if the DateTime string has 0000000 (7 digits of precision).
• SQL Server’s datetime and datetime2 types don’t support nanosecond-level precision.
• EF Core attempts to translate it, but fails with SQL conversion errors

Please consider extending the GridColumn component to include fine-grained header presentation properties, such as:

• HeaderAlignment (e.g., Left, Center, Right)
• WrapHeaderText (bool)
• HeaderTooltip or HeaderAdornmentTemplate
  

These enhancements would dramatically improve clarity and usability in complex data grids.

Why This Is Important

In enterprise-grade applications — like ERP dashboards, financial reporting, or cutover schedules — grids are dense and loaded with meaning. Users rely heavily on headers to interpret the data beneath, especially when:

• Column headers are long or require abbreviations.
• Users need contextual guidance without clutter.
• Alignment improves visual scanning and aesthetics.

Hi there,

I have a TelerikGrid with a DateTime column. I use a custom FilterEditorFormat which is localizable depending on the user settings, e.g. "dd/MM/yyy HH:mm:ss". Unfortunately, any '/' in the date component is always replaced by the current culture's DateSeparator. Using any other separator works, e.g. '-'. 

Expectation: Use the FilterEditorFormat without modification, unless it's a standard format string like "g" or "D".

I already traced it down to Telerik's FormatHelper class and it seems like a quick fix.

Steps to reproduce:

• Create a TelerikGrid with a DateTime column and a FilterEditorFormat as shown above.
• If required, change the DateSeparator to anything else but '/'.
• Run and open the filter dialog

Please let me know if you need any additional information.

Best regards

Andreas

Please consider adding a TooltipTemplate parameter to the GridColumn component to allow developers to define custom tooltips for each cell using the same template logic available in CellTemplate.

Why This Matters

In enterprise applications — especially in ERP dashboards, cutover schedules, and KPI reports — data often needs contextual clarification. While tooltips are supported globally or via title attributes, there’s currently no clean, built-in way to customize tooltips per column using templating logic.

Please consider adding new grid-level properties to control visual styling and editing behavior more intuitively:

• HeaderThemeColor
• ShowGridLines
• EditModeDisplay (e.g., None, ValueOnly, All, Auto)
  

These options would provide teams with greater flexibility to align grids with branding, accessibility, and user interaction standards.

Why This Is Valuable

Grids are the centerpiece of most enterprise applications — and users rely on visual consistency and responsive interaction. Today’s grids need to:

• Match branding and accessibility guidelines (dark/light, color accessibility).
• Visually separate data (e.g., grid lines on for financial reports, off for dashboards).
• Clearly communicate edit state (inline, batch, or value-only editing).
  

These settings would empower developers to deliver purpose-built grids without deep CSS overrides or workarounds.

Please consider adding built-in support for a TextTruncationWithAction or TruncateWithButton mode on GridColumn components. This feature would display long text as truncated with ellipsis (...) and a button or icon to reveal the full content, such as in a modal or popover.

Why This Is Needed

In enterprise applications like ERP, cutover planning, or audit logs, we often display descriptions, notes, or comments that can span multiple lines. However:

• Wrapping ruins compact grid layouts.
• Truncating with ellipsis alone hides valuable content.
• Users need quick, inline access to full text without leaving the grid.

The issue occurs only if the Signature is initially rendered in a container with display: none style. If I use visibility: hidden, I don't see a problem.

Real use case in which this is a problem: an accordion where the second pane is not opened.

Reproduction code: https://blazorrepl.telerik.com/QfYeuZPv28LlBmBx56.

Steps to reproduce:

1. Test signinig in the Signature #1 pane - Signature behaves properly.
2. Open the  Signature #2 pane and test signing - the scale is wrong.

The RadioGroup's FocusAsync() method does not work. To reproduce, run this example and press the button: https://docs.telerik.com/blazor-ui/components/radiogroup/overview#radiogroup-reference-and-methods

===

A possible workaround is to use JavaScript to focus the first or the selected <input> element:

@inject IJSRuntime js

<TelerikButton OnClick="@FocusRadioGroup">Focus RadioGroup</TelerikButton>

<TelerikRadioGroup Data="@RadioGroupData"
                   Class="my-radiogroup"
                   @bind-Value="@RadioGroupValue"
                   ValueField="@nameof(ListItem.Id)"
                   TextField="@nameof(ListItem.Text)">
</TelerikRadioGroup>

@* Move JavaScript code to a separate JS file in production *@
<script suppress-error="BL9992">function focusRadio(RadioGroupValue) {
        var mrg = RadioGroupValue == null ?
            document.querySelector(".my-radiogroup .k-radio-list-item input") :
            document.querySelector(`.my-radiogroup .k-radio-list-item input[value='${RadioGroupValue}']`);
        if (mrg) {
            mrg.focus()
        }
    }</script>

@code{
    private int? RadioGroupValue { get; set; }

    List<ListItem> RadioGroupData { get; set; } = new List<ListItem>() {
        new ListItem { Id = 1, Text = "Foo" },
        new ListItem { Id = 2, Text = "Bar" },
        new ListItem { Id = 3, Text = "Baz" }
    };

    private async Task FocusRadioGroup()
    {
        await Task.Delay(1);

        await js.InvokeVoidAsync("focusRadio", RadioGroupValue);
    }

    public class ListItem
    {
        public int Id { get; set; }
        public string Text { get; set; } = string.Empty;
    }
}

Telerik UI for Blazor requires unsafe-inline styles in order to render style attributes from the .NET runtime.

Please add support for strict CSS CSP without the need for unsafe inline styles.

===

TELERIK EDIT:

Due to the complexity and required effort to add strict CSS CSP support:

• The feature request must gather enough votes.
• We may implement it gradually. That's why, everyone who is interested, please specify the exact components and features that you need to be compliant sooner.

Would like a parameter in the grid definition that would display a Clear/Refresh button to return the grid to all originally selected records.  This feature would work similar to the Excel clear filter function.  

===

TELERIK EDIT: To reset the Grid filters, you can clear the FilterDescriptors collection and the SearchFilter property in the Grid state. Here is an example:

https://blazorrepl.telerik.com/cfEoatOr000uBdgW48

    private TelerikGrid<Product>? GridRef { get; set; }

    private async Task ClearGridFilters()
    {
        var gridState = GridRef!.GetState();

        gridState.FilterDescriptors = new List<IFilterDescriptor>();
        gridState.SearchFilter = default;

        await GridRef.SetStateAsync(gridState);
    }
