Description

Changing the "day" part of the DatePicker value is inconsistent.

Steps To Reproduce

Run this example: https://blazorrepl.telerik.com/QfOLwTvp03DVHJ4C35

1. Click on the "day" part of the DatePicker input and enter 22032025. The result is: 22-03-2025.
2. Click the "day" part again and enter 02.

Actual Behavior

The value changes to: 20-02-2025.

After the initial unsuccessful attempt to change the day to 02, subsequent attempts will work as expected. You may re-focus the "day" part and type 02.

Expected Behavior

The value should change to 02-03-2025.

We would like to get the datetime picker to autofill the year when entering just two digits for the year with a format of dd-MM-yyyy HH:mm:ss.

So when you enter 23-04-25 it changes to 23-04-2025. Currently it changes it to 23-04-0025, which isn't our desired result.

Something along the lines of how this works: https://jsfiddle.net/anbdwL0h/ but then with a 4 year digit format as result.

In our application "Today" is NEVER a valid selection.  But there is no way to turn it off.

Yes, we realize that we can create our own header template.  But then we have to reproduce the next/previous functionality, for every single instance of the component -- and we have many dozens of them.

1. See the DatePicker Validation Demo
2. Highlight the year
3. Start typing 2029
4. See that even on the first input stroke the validation is triggered.

As a workaround, you can add the DebounceDelay parameter with a high number as in this REPL link.

Hi

I have created a REPL here: https://blazorrepl.telerik.com/QHYGbTPk59IqOcEU51

to reproduce the issue I am talking about:

1. click on the cell
2. Press the 'Delete' Key
3. Press the 'Enter' Key

you will notice that the value displayed below the table is what was previously in the cell

I would have expected the value to be null which can be achieved via

1. click on the cell
2. Press the 'Delete' Key
3. Click outside the cell
   

When dragging the mouse to select the whole input value, only the first segment on the left remains selected after releasing the mouse. The issue is reproducible in the DatePicker demo once you select a date. Video: https://app.screencast.com/Eoa6Xj2MzfOPN.

The problem is only reproducible in Firefox, the whole input is properly selected in Chrome and Edge.

When the user navigates between the views, the DatePicker currently fires a ViewChanged event. This event provides the new view (Decade, Month etc.) but there is no way to detect the selection that the user made in the previous view.

For example, if am in the Decate view, as soon as I select a year, the DatePicker will switch to Month view. The problem that I am facing is that I cannot get the year selected from the Decade view. I need that, so I can display it in my custom HeaderTemplate.

Delete the input, choose a date from the dropdown. The issue is that the first picker remains invalid, while it is valid, a keyboard interaction with the input is required to clear the invalid state.

Reproducible:

@using System.ComponentModel.DataAnnotations;

    <EditForm Model="ModelData">
        <DataAnnotationsValidator />
        <ValidationSummary />
        <br /><br />
        <span>Not nullable</span> @ModelData.Date<br />
        <Telerik.Blazor.Components.TelerikDatePicker @bind-Value="ModelData.Date" Min="DateTime.MinValue" Max="DateTime.MaxValue"></Telerik.Blazor.Components.TelerikDatePicker><br /><br />
        <span>Nullable</span> @ModelData.Date2<br />
        <Telerik.Blazor.Components.TelerikDatePicker @bind-Value="ModelData.Date2" Min="DateTime.MinValue" Max="DateTime.MaxValue"></Telerik.Blazor.Components.TelerikDatePicker><br /><br />
    </EditForm>

@code  {

    public MyModel ModelData { get; set; }

    protected override void OnInitialized()
    {
        ModelData = new MyModel();
    }

    public class MyModel
    {
        public string Name { get; set; }

        [Required(ErrorMessage = "Non nullable required")]
        public DateTime Date { get; set; } = DateTime.Today;

        [Required(ErrorMessage = "Nullable required")]
        public DateTime? Date2 { get; set; } = DateTime.Today;
    }
}

For some reason I'm unable to select the date 01/03/2000 when using the date picker to select the date. Only thing special about this date is its exactly 24 years ago today.

I was able to reproduce in repl. https://blazorrepl.telerik.com/QyYFkdbU34QbG0Te32

I also attached a video so you can review the steps followed and result.

Steps to reproduce

1. Add a DatePicker
2. Bind it to nullable DateTime object
3. Use the dd.MMM.yyyy format
4. Select any date and when the popup is closed press any numeric key on the keyboard.

Currently, if the ReadOnly parameter value is set to 'true,' the user can modify the value of the DateInput by using the arrow keys.

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.

• When a user wants to clear a date a lot of time they will click at the end of the component and start hitting back space.  However, after the year is cleared at the end if you keep clicking back space it does not continue to also clear the month and so on.
• I'd like an option that allows free form typing and it does not parse as you type.  It just allows you to enter the text input like if it were a regular text box.  When you click enter or drop out of focus then it will parse the value as appropriate to what the user enters in.  This would be an example: https://www.matblazor.com/DatePicker .   The user could type in whatever format they want and then it'll parse it into the format that I've selected.  They could enter 2023-07-06, 07.06.2023  04/06/1983 4/6/1983 4/6/83 and it would parse as appropriate and the set the value as appropriate.
• When you single click into a date picker text box it will highlight the closest date part.  However, if I then try to click again to select the entire date, where the user is just trying to copy and paste it'll do this weird dragging of the highlighted date portion with a do not enter icon.  I would expect that it would allow you to continue selecting the entire contents of the text box so I can then copy and paste.
• If I only focus on for example the first character of the text box and then try to paste in a value from another form it does not take the copy and paste.  I would honestly expect that copy and paste regardless of what individual element that you are focused on what accept the new value that I am trying to paste.  If I paste in 07/06/2023 anywhere in the text box it should parse that and replace the entire date like if I selected the entire contents of the date and pasted it in.  The free form typing would resolve the useability issues here though.
• For time picker I'd like some different UI options.  The existing implementation is ok, but if we had options to format the the timer picker like: https://mudblazor.com/components/timepicker#api or other times if we want to lock them in to only specific time intervals it's better to just have them select a time from a drop down.  I realize that the drop down method could be implemented in other ways but if it was just baked into the control it would be a lot easier.
