When you select a date in DropDownList with dates in it (List<DateTime>), the @bind-Value is shaving off the milliseconds.

===ADMIN EDIT===

In the meantime, as a workaround for displaying milliseconds correctly, you can bind the DropDownList to a model. This way, you can use the "Id" to retrieve the selected item and display its precise milliseconds. Below is an example I've prepared to demonstrate this approach:

Selected value: @myDdlData.ToList().Where(x => x.Id == selectedValueId).FirstOrDefault()?.MyValueField.ToString("MM/dd/yyyy HH:mm:ss.fff")
<br />

<TelerikDropDownList Data="@myDdlData" 
                     TextField="MyTextField" 
                     ValueField="Id" 
                     @bind-Value="selectedValueId">
</TelerikDropDownList>

@code {
    public class MyDdlModel
    {
        public int Id { get; set; }
        public DateTime MyValueField { get; set; }
        public string MyTextField => MyValueField.ToString("MM/dd/yyyy HH:mm:ss.fff"); // Display formatted DateTime
    }

    private int selectedValueId { get; set; } = 1;

    private IEnumerable<MyDdlModel> myDdlData = GenerateRandomDateTimes(20);

    private static IEnumerable<MyDdlModel> GenerateRandomDateTimes(int count)
    {
        Random random = new Random();
        DateTime startDate = DateTime.Now;

        return Enumerable.Range(1, count)
            .Select(x => new MyDdlModel
            {
                Id = x, // Unique integer Id
                MyValueField = startDate.AddDays(x)
                    .AddMinutes(random.Next(0, 60))
                    .AddSeconds(random.Next(0, 60))
                    .AddMilliseconds(random.Next(0, 1000))
            }).ToList();
    }
}

I have been having issues adding the month view to a Telerik Blazor scheduler component, when there is grouping. It gives a null reference error any time I try to switch to the month view. I also tried it using the available demo for grouping in Telerik REPL, the only difference I found between my code and the demo was that I had used the ItemsPerSlot parameter.  I added this to the demo, and was able to reproduce the error I was seeing, and I have attached the console output from the REPL demo. I believe there is either a bug with the ItemsPerSlot being used in conjunction with grouping on a scheduler component, or some instruction missing from how to set it up properly to prevent this null reference issue. 

Changed code:

<SchedulerMonthView ItemsPerSlot="5"></SchedulerMonthView>

Demo used:

The PDF standard allows two ways to configure Acro fields and relate them to inputs (widget annotations):

1. The field can be independent of the input widget. There can even be multiple inputs that point to the same field.
2. The field and the widget can be represented by the same object in the PDF file.

Adobe Acrobat supports both options. Telerik PdfProcessing supports only the first option, which is more commonly used. The PDF Viewer supports only the second option. If the PDF Viewer loads a file with the first configuration, the component saves new field values in such a way that they can't be retrieved by PdfProcessing. Moreover, if the PDF file is opened locally, it looks like the new values are there, but when you click on a field, the original value shows. The new value behaves like a placeholder rather than a real value.

To Reproduce

1. Open a file with Acro fields in the PDF Viewer with enabled form filling
2. Edit the fields and save the file.
3. Open the file with a desktop client like Adobe Acrobat Reader.
4. Click on a textbox.
5. Result - the old value shows. Instead, the new value should persist.
   

Would it be possible to have the ability to create compact TreeList's similar to how we can now in a Grid? Since Size=ThemeConstants.Grid.Size.Small is available a Grid now it seems natural this would be a next step. If we can be provided with a work around for the time being that would be great.

The FileManager crashes with a null reference exception when the selected file is deleted while the preview pane is open.

Reproduction with OnRead

I made a Blazor REPL reproduction: https://blazorrepl.telerik.com/mcuCGpYr4223mhWY49. Run and observe the person label is overlapping the dropdown.

How to reproduce:

1. Get code from the Remote Data Example.
2. Surround the ComboBox with a TelerikFloatingLabel, it will then look like this:

   <TelerikFloatingLabel Text="Person">
   <TelerikComboBox 
                   TItem="@Person" TValue="@int"
                    ScrollMode="@DropDownScrollMode.Virtual"
                    OnRead="@GetRemoteData"
                    ValueMapper="@GetModelFromValue"
                    ItemHeight="30"
                    PageSize="20"
                    TextField="@nameof(Person.Name)"
                    ValueField="@nameof(Person.Id)"
                    @bind-Value="@SelectedValue"
                    Filterable="true" FilterOperator="@StringFilterOperator.Contains">
       <ComboBoxSettings>
           <ComboBoxPopupSettings Height="200px" />
       </ComboBoxSettings>    
   </TelerikComboBox>
   </TelerikFloatingLabel>

Bug report

Reproduction of the problem

(bug report only)
Reproducible in the demos: https://demos.telerik.com/blazor-ui/dropdowntree/overview

1. Click somewhere in the component to open its dropdown

Current behavior

(optional)
For a brief moment the filter input in the dropdown appears focused, but then the focus moves to the first item in the list. If the user clicks the “down arrow” icon to open the dropdown, the filter input is focused as expected.

Expected/desired behavior

The filter input is focused regardless where in the component the user clicks.

Environment

• Kendo/Telerik version: 14.0.0
• Browser: [all ]

Bug report

Reproduction of the problem

(bug report only)

1. Run this example: https://blazorrepl.telerik.com/mUOqQflm56D4xScx54
2. Select a font in the FontFamily dropdown.
3. Click the UnorderedList tool in the Editor’s toolbar.
4. A bullet is added and the FontFamily tool loses its value.
5. Click right after the added bullet.
6. Once again select a font in the FontFamily drodown.
7. Click the UnorderedList tool in the Editor’s toolbar to remove the bullet.
8. The FontFamily tool loses its value.

Current behavior

(optional)
Provide additional information if the steps for reproducing the faulty behavior are not sufficient to describe the issue.

Expected/desired behavior

The FontFamily tool should keep its value when an unordered list is added/removed.

Environment

• Kendo/Telerik version: 14.0.0

Bug report

Reproduction of the problem

(bug report only)
1. Run this example: https://blazorrepl.telerik.com/cAkKcTYZ39RLN4r548
2. Open the ComboBox popup and navigate through the items in the list by holding down “Down Arrow” key, or by pressing the key rapidly.

Current behavior

(optional)
An exception is thrown and instead of continuing with the next batch of items, navigation is stuck on the first item in the list.

Expected/desired behavior

Navigation continues from the next loaded batch of items.

Environment

• Kendo/Telerik version: 14.0.0

The problem is that the ValueChanged fires without an actual change in the Editor content - just click in it. I reproduce this issue in the following scenario:

• The value contains a self-closing tag.
• I click in the Editor the first time. Consecutive clicks in the Editor do not cause ValueChanged to fire.

Reproduction: https://blazorrepl.telerik.com/wfaxnvPv19jUCGhd15.

The window actions OnClick handler does not execute when a predefined action (e.g. Close) is triggered. This prevents custom logic from running during standard close operations.

Reproducible on version 14.0.0

Repro: https://blazorrepl.telerik.com/wqaJcWbu45qZxbeX49

Issue: Opening and closing a window will cause the window to reopen with each following OnClick. This seems to have been introduced with the upgrade to .net10
