Please provide item templates for the file list, similar to:

• https://www.telerik.com/kendo-angular-ui/components/uploads/upload/templates/
• https://demos.telerik.com/kendo-ui/upload/templates

Please expose the modified date of the selected and uploaded files, similar to the standard Blazor <InputFile> component.

This request applies to both the FileSelect and the Upload components.

One can generally loop through a collection of items to create several TabStrip instances as shown in the Tabs Collection article.

However, when I am dynamically adding or removing tabs I am hitting a variety of problems targeting:

• The active tab is not correctly set;
• The focus is not always set on the active tab;
• Upon adding/removing a tab, all tabs are re-created and thus their content cannot be persisted;

Please add support for dynamic tabs.

I realize we can build Blazor components to associate "label" to controls, but IMHO, this should come standard with any control tool set. Reasons:

1.  Coding simplicity

2.  Automatic theme inheritance

3.  Flexibility in label positioning relative to the control (left, right, top, bottom)

Example:

<TelerikCheckBox Label="Is Chasssis" LabelPosition="left" @bind-Value="equipment.IsChassis"/>

I realize you folks put some effort into a "Floating Label", but my users have rejected this implementation because:

1.  Having Text in a label as a means to identify the label makes them think a value is already provided (so they try to remove it or call for support).

2.  When typing in the label and the appearance of the label identification appears above adds to their confusion as they are used to seeing validation errors appearing above a label.

Please add support for programmatic exporting of Grids (SaveAsExcelFileAsync() and ExportToExcelAsync() ) with a GridExcelExportOptions argument and multi-column headers.

A potential workaround is to programmatically click the built-in export command button, which can even be hidden:

@using Telerik.Blazor.Components.Grid

@inject IJSRuntime JS

<PageTitle>Home</PageTitle>

<TelerikGrid Data="@GridData">
    <GridToolBarTemplate>
        <TelerikButton OnClick="@ExportGridWithOtherColumns">Export Programmatically</TelerikButton>
        <GridCommandButton Class="hidden-export-button" Command="ExcelExport">Export Natively</GridCommandButton>
    </GridToolBarTemplate>
    <GridSettings>
        <GridExcelExport OnBeforeExport="@OnGridBeforeExport" />
    </GridSettings>
    <GridColumns>
        <GridColumn Field="@nameof(Product.Id)" Width="100px" />
        <GridColumn Field="@nameof(Product.Name)" Width="120px" />
        <GridColumn Title="Product Details">
            <Columns>
                <GridColumn Field="@nameof(Product.Group)" Width="180px" />
                <GridColumn Field="@nameof(Product.Price)" DisplayFormat="{0:c2}" Width="120px" />
                <GridColumn Field="@nameof(Product.Quantity)" DisplayFormat="{0:n0}" Width="120px" />
                <GridColumn Field="@nameof(Product.Released)" DisplayFormat="{0:d}" Width="180px" />
                <GridColumn Field="@nameof(Product.Discontinued)" Width="100px" />
            </Columns>
        </GridColumn>
    </GridColumns>
</TelerikGrid>

<style>
    .hidden-export-button {
        display: none;
    }

<script suppress-error="BL9992">

                Price = rnd.Next(1, 100) * 1.23m,
                Quantity = rnd.Next(0, 10000),
                Released = DateTime.Today.AddDays(-rnd.Next(60, 1000)),
                Discontinued = i % 4 == 0
            });
        }
    }

    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; } = string.Empty;

1. Can you please add the ability to choose a chevron instead of a caret to signify there are menu items under it?

2. Can you please add the ability to collapse/expand the menu and just show the icon when collapsed.

Thank you.

I want to add more fields to the scheduler create/edit popup. Currently, this is possible by creating a custom edit form. However, this customization would be easier if the Scheduler exposed a Popup Form Template similar to the Grid.

ADMIN EDIT

A necessary prerequisite for exposing this is to first add a State feature in the Scheduler. This will allow programmatic control over the edited item.

Hello,

I have a question regarding the persistence of content when blazor splitter panes are collapsed and expanded.

Please refer to the attached project to see the issue that I'm having.

Regards,

Gerard

Hi !

I tried using the combobox but, since my datasource is too big and I need grouping, therefore virtualization is not possible, I need to do the filtering on the server side, using the OnRead method to fetch my data based on what the user has entered in the input field. The problem is that the client side filtering is always active and I can't reproduce the same type of filtering I do server side on the client side and I lose some results. I think it would be really nice if we could specify to not filter client side or something like that, to give us more control.

Thank you very much !

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.
