Release 4.6.0 (11 Oct 2023) (R3 2023)

Hello,

in some cases there is no way to scroll grid using mousewheel. Try this REPL please - https://blazorrepl.telerik.com/GdkXuLuX10P8sOF040. Scroll down, focus any cell in the last row and try to scroll up using your mouse wheel again.  Grid always scrolls back to the last row.

Can you check that please?

Very thanks.

Miroslav

Using the following configuration does not produce the expected result:

 

 <GridSettings>
        <GridPopupEditFormSettings ButtonsLayout="FormButtonsLayout.Center"/>
 </GridSettings>

 

The button layout is always left no matter what you choose.

ADMIN EDIT

Possible workarounds for the time being are to position the buttons with CSS or use a Popup Buttons Template.

The TelerikEditor demos all show bind-Value being used to marshal HTML in and out of the editor:

<TelerikEditor @bind-Value="@TheEditorValue" Width="650px" Height="400px"></TelerikEditor>

However, this causes problems - the underlying ProseMirror component emits it's own HTML (e.g. for image drag handles), which is visible in the bound Value property.

We need to be able to export "clean" HTML from the viewer, otherwise we end up saving this superflous HTML as part of our document.

Code

This REPL shows the issue:

https://blazorrepl.telerik.com/mHODmObJ36vZ7ivR09

@page "/editor/tools"

@using Telerik.Blazor.Components.Editor 

<TelerikEditor Tools="@EditorToolSets.All"
               Height="300px"
               @bind-Value="@Value"
               EditMode="EditorEditMode.Div"
               ></TelerikEditor>

<pre style="white-space: pre-wrap;">@Value</pre>

@code {
    public string Value { get; set; } =
        "<img src=\"img/toolbar-assets/repl-logo.svg\" />";
}

Steps to Reproduce

1. Open the REPL and click "Run" - observe that the bound HTML is simply

<img src="img/toolbar-assets/repl-logo.svg" />

2. Click on the Telerik logo image inside the editor - observe that the bound HTML is now

<p><img src="img/toolbar-assets/repl-logo.svg" contenteditable="false" draggable="true" class="ProseMirror-selectednode"><div class="k-editor-resize-handles-wrapper ProseMirror-widget" style="width: 857px; height: 78px; top: 8px; left: 8px;" contenteditable="false"><div class="k-editor-resize-handle southeast" data-dir-image-resize="southeast"></div><div class="k-editor-resize-handle east" data-dir-image-resize="east"></div><div class="k-editor-resize-handle south" data-dir-image-resize="south"></div><div class="k-editor-resize-handle north" data-dir-image-resize="north"></div><div class="k-editor-resize-handle west" data-dir-image-resize="west"></div><div class="k-editor-resize-handle southwest" data-dir-image-resize="southwest"></div><div class="k-editor-resize-handle northwest" data-dir-image-resize="northwest"></div><div class="k-editor-resize-handle northeast" data-dir-image-resize="northeast"></div></div><br class="ProseMirror-trailingBreak"></p>

3. Deselect the image - observe that the bound HTML no longer contains the image handles etc, but is still more verbose than when we started

<p><img src="img/toolbar-assets/repl-logo.svg" contenteditable="false" draggable="true" class=""><br class="ProseMirror-trailingBreak"></p>

4. At any point during the above steps, click the "View HTML" button in the Editor toolbar - observe that it is able to present a "clean" structure which contains no ProseMirror markup etc.

Requirements

How do we access this HTML via the TelerikEditor Blazor APIs?

NVDA is not narrating Name and narrating selected value twice for the dropdowns which are present in the 'Filter' dialog in column headers.

Release 4.6.0 (11 Oct 2023) (R3 2023)

The Splitter separator has role="separator" attribute. When such a role is set and the separator is focusable, it is required that aria-valuenow attribute is also set. Currently, the Splitter separator does not have such an attribute.

From our point of view, the expected result is - NVDA / Narrator should announce separator value with respect to the position value for the separator (or no separator value at all).

One really nice feature MudBlazor UI has is the Dialog component. You can pass a component to the Dialog Service and it will display it in a modal dialog.

Existing Example

An example of this would be:

             var orderParams = new DialogParameters();
                orderParams.Add("SelectedOrderHeader", Item);
                orderParams.Add("EditMode", "Add");
                orderParams.Add("SelectedOrderDetail", new OMSOrderDetail());
          
                DialogService.Show<OrdersDetailForm>("Click on orders grid to continue", orderParams);

 

<OrderDetailsForm> is a custom Blazor component.

Does the Telerik Blazor dev team have any plans for implementing something like this?

Release 4.6.0 (11 Oct 2023) (R3 2023)

This issue has to do with keyboard support, where if the step index is changed programmatically, and then the user tabs back onto the wizard stepper, then the focus class is on the wrong step.  The active step is correct in the stepper, but the focus outline is on the step prior to the programmatic index change.  I have created a repl here:

https://blazorrepl.telerik.com/wcbmlAlj23ZwNsxf21

If you click the Move to 3rd Step button it will switch the wizard to the 3rd step correctly.

Tab to the stepper, and step 1 will have the outline focus class, the focus will actually be on the correct step (step 3).

Pressing the right arrow key will move to Active Step 4, but the outline focus class will be moved to step 2.  

Pressing the left arrow key will then fix the outline class.

I would expect that when changing the step index programmatically, that the outline focus class on the stepper would be displayed for the step that the index was changed to.  It becomes confusing for keyboard users.

While the menu is usable the way it is, it could be better. If you take a look at the example menu in the best practices link that I provided in the original post, you will see what I mean. Some of the differences include the following:

  • For any item in your menu that is a link and not a submenu, the item is read by NVDA saying "collapsed" which is unnecessary and could get frustrating to a screen reader user. This doesn't happen with the best practices menu.
  • Using the keyboard left and right buttons move the focus to the next adjacent menu item, but it doesn't set focus to the top menu item and read it. Instead, it just says "Menu". The best practices will focus on the top menu item when moving left or right.
  • The escape key isn't being used to cancel out of the dropdown on the menu. A user should be able to click ESC and the menu should close, with focus set back to the parent menu item. This presents a navigational issue for those submenu items that have further submenus. In order for a user to navigate to an adjacent menu, they need to traverse to the left all the way down the submenus before it will move on to the next adjacent top item. With the ESC key, they can move back to the parent item, and then navigate right or left from there.
  • Tabbing out of the menu when the focus is on the submenu, messes up the tab order, so the shift tab doesn't navigate back to the menu. If the focus is on one of the top menu items, then tabbing out and back works. However, it should set the focus back to the last top menu item that has focus, not the first item. So if the 3rd item had focus, then tabbing out and then shift-tabbing back should set the focus back to the 3rd item, not the first item. And if you tab out from a submenu item from the 2nd parent item, then shift-tab should bring them back to the 2nd parent item.

When AutoClose is set to false and you select more than one item, then only the first one will be highlighted in the popup. Items are selected and present in the input but are visually highlighted.

Reproduction 

1. Run this REPL sample
2. Select more than one item from the drop-down
3. Only the first selected item is highlighted as such
4. Video example

Current

Not all selected items are highlighted, which does not match the Input.

Expected

All selected items in the drop-down should be highlighted.

I want to display 2 or 3 panes in a splitter but after hiding the middle pane and showing it again its position is not saved, it appears at the end of the splitter as per the example below.

What is the best way to keep pane order ?

    <FormItems>
        <AuthorizeView>
            <Authorized>
                <FormItem Field="First"/>
            </Authorized>
        </AuthorizeView>
        <FormItem Field="Second"/>
    </FormItems>
</TelerikForm>

will end up like

<TelerikForm>
    <FormItems>
        <FormItem Field="Second"/>
        <FormItem Field="First"/>
    </FormItems>
</TelerikForm>

Accessibility issue
impacts screen reader user

[WCAG 1.3.1 level A] [WCAG 4.1.3 level AA]

tested using NVDA on chrome browser

on selecting upload button (w/ files already chosen) user is not advised the overall status of the files or individual files.

A visual user is informed;

  • overall status as 'done'.
  • completeness of individual files

This has not been 100% tested, as the upload was not targeted to an end point.

Suggestion: use aria-live

Also note, on selecting the upload button the focus is returned to input, and input says no files.

Hello,

I have an issue with TelerikDatePicker globalization. It works fine at all, but "Today" has the same translation.


I've used code like this:

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo(MyStringLanguage);

And it still works only for "days" and "months". Could you please tell about current situation about localization and globalization or maybe to suggest some different solution.

Thanks for your help.

I would like to add a feature similar to the Tag Mode in the Kendo suite 

 

===========

ADMIN EDIT

===========

In the meantime, there are two possible workarounds:

1. Mimic the desired 'single' TagMode behavior and display the number of selected items inside the MultiSelect, instead of the selected items themselves.

This approach uses custom CSS, which hides the list of selected items and displays a dynamically updated count value. The most important bits are highlighted:

UI for Blazor 2.30

<TelerikMultiSelect Data="@Products" Class="single-tag-mode"
                    @bind-Value="@SelectedProductIDs"
                    ValueField="@nameof(Product.ProductID)"
                    TextField="@nameof(Product.ProductName)"
                    Placeholder="Select Products">
</TelerikMultiSelect>

<style>
    .single-tag-mode ul.k-reset {
        float: left;
    }

    .single-tag-mode ul.k-reset li.k-button {
        display: none;
    }

    .single-tag-mode ul.k-reset:before {
        content: "Selected items: @SelectedProductIDs.Count";
        display: inline-block;
        line-height: 1.8em;
        padding: 0 7px;
        vertical-align: bottom;
        border: 1px solid rgba(0, 0, 0, 0.08);
        background: #f5f5f5 linear-gradient(rgba(0, 0, 0, 0), rgba(0, 0, 0, 0.02));
    }
</style>

@code {
    List<Product> Products = new();
    List<int> SelectedProductIDs = new();

    protected override async Task OnInitializedAsync()
    {
        for (int i = 1; i <= 10; i++)
        {
            Products.Add(new Product()
            {
                ProductID = i,
                ProductName = "ProductName " + i
            });
        }

        await base.OnInitializedAsync();
    }

    public class Product
    {
        public int ProductID { get; set; }
        public string ProductName { get; set; }
    }
}

 

UI for Blazor 3.0

 

<TelerikMultiSelect Data="@Products" Class="single-tag-mode"
                    @bind-Value="@SelectedProductIDs"
                    ValueField="@nameof(Product.ProductID)"
                    TextField="@nameof(Product.ProductName)"
                    Placeholder="Select Products">
</TelerikMultiSelect>

<style>
    .single-tag-mode .k-input-values {
        float: left;
    }

    .single-tag-mode .k-input-values .k-chip {
        display: none;
    }

    .single-tag-mode .k-input-values:before {
        content: "Selected items: @SelectedProductIDs.Count";
        display: inline-block;
        line-height: 1.8em;
        padding: 0 7px;
        vertical-align: bottom;
        border: 1px solid rgba(0, 0, 0, 0.08);
        background: #f5f5f5 linear-gradient(rgba(0, 0, 0, 0), rgba(0, 0, 0, 0.02));
    }
</style>

@code {
    List<Product> Products = new();
    List<int> SelectedProductIDs = new();

    protected override async Task OnInitializedAsync()
    {
        for (int i = 1; i <= 10; i++)
        {
            Products.Add(new Product()
            {
                ProductID = i,
                ProductName = "ProductName " + i
            });
        }

        await base.OnInitializedAsync();
    }

    public class Product
    {
        public int ProductID { get; set; }
        public string ProductName { get; set; }
    }
}

 

 

2. Restrict the component's size and allow scrolling to see all selected items.

Use some custom CSS to set desired height of the container holding the selected items (.k-chip-list) and to control its overflow. You can use the Class parameter of the Multiselect to set your custom CSS class to the main wrapping container of the component and style a specific instance of the component, not all instances on the page/app.

In terms of controlling the container's height, you can:

  • Set fixed height : the container will have fixed height and if its content exceeds it, a scrollbar will appear.

  • Set max-height: when filled with content, the container will expand until it reaches its max height. Scrollbar will appear afterwards.
<style>
    .my-multiselect{
        overflow: auto;
        max-height: 60px;
    }
</style>

<TelerikMultiSelect Class="my-multiselect"
                    Data="@Countries"
                    @bind-Value="@Values"
                    Placeholder="Enter Balkan country, e.g., Bulgaria"
                    Width="350px" ClearButton="true" AutoClose="false">
</TelerikMultiSelect>

@code {
    List<string> Countries { get; set; } = new List<string>();
    List<string> Values { get; set; } = new List<string>();

    protected override void OnInitialized()
    {
        Countries.Add("Albania");
        Countries.Add("Bosnia & Herzegovina");
        Countries.Add("Bulgaria");
        Countries.Add("Croatia");
        Countries.Add("Kosovo");
        Countries.Add("North Macedonia");
        Countries.Add("Montenegro");
        Countries.Add("Serbia");
        Countries.Add("Slovenia");

        base.OnInitialized();
    }
}
