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:

Blazor Scheduler (Event Calendar) Demos - Grouping | Telerik UI for Blazor

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.

Support multiple users editing the same content in an editor.

This would be similar to the editor in something like confluence or online Word.

Hi,

I would like checkbox support including the check all checkbox on the multiselect component like: https://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/functionality/checkbox-support

The url below shows how to create custom checkboxes in the multiselect component but adding a check all checkbox in the headertemplate does not update the multiselect popup

https://docs.telerik.com/blazor-ui/knowledge-base/multiselect-checkbox-in-dropdown?_ga=2.50111909.206897922.1631541466-694624900.1630583797&_gac=1.246637872.1631604077.EAIaIQobChMI8PnX6Pb98gIVkwCLCh381AjMEAAYASAAEgLROPD_BwE

Telerik input components inside EditorTemplate render the whole grid on each keystroke

 

<AdminEdit>

As a workaround, you can use the standard Input components provided by the framework together with a CSS class that would visually make them like the Telerik Input Components. An example for the TextArea:

<InputTextArea class="k-textarea" @bind-Value="@myValue"></InputTextArea>

</AdminEdit>

We are using the blazor chat component with Microsoft.Extensions.AI and IChatClient. Currently during a long response stream the chat repeatedly scrolls to the bottom automatically as the response updates. When I use use my mouse wheel to scroll to the top it immediately auto scrolls me back to the bottom.

A user needs to be able scroll to the top as the response is streaming in. If the user manually scrolls the auto scrolling should stop. Any subsequent messages sent in the same chat session should resume auto scroll. This is the behavior seen in most AI chat interfaces like chatGPT and is what most users expect. 

For more info and a video refer to support ticket: 1712888

Thanks, Justin.
