TimeDurationPicker in Razor Pages

Razor Pages is an alternative to the MVC pattern that makes page-focused coding easier and more productive. This approach consists of a cshtml file and a cshtml.cs file (by design, the two files have the same name).

You can seamlessly integrate the Telerik UI TimeDurationPicker for ASP.NET Core in Razor Pages applications.

This article describes how to configure the TimeDurationPicker component in a Razor Pages scenario.

Binding the TimeDurationPicker to a PageModel Property

To bind the TimeDurationPicker to a property from the PageModel, follow the next steps:

Add a property to the PageModel that must bind to the TimeDurationPicker.

csharp

public class IndexModel : PageModel
{
    [BindProperty]
    public decimal? Duration { get; set; }

    public void OnGet()
    {
        // Assign a value in milliseconds (1h 30m = 5400000 ms)
        Duration = 5400000m;
    }

    public void OnPost()
    {
        // Duration will be populated with the submitted value
    }
}

Declare the PageModel at the top of the page.
Razor
```
@page
@model IndexModel
```

Bind the TimeDurationPicker to the property using the TimeDurationPickerFor() configuration.

Razor
@page
@model IndexModel

@(Html.Kendo().TimeDurationPickerFor(m => m.Duration)
      .InputMode("numeric")
      .Columns(c =>
      {
          c.Hours().Format("## hours ");
          c.Minutes().Format(" ## minutes");
      })
)
Razor
@page
@model IndexModel
@addTagHelper *, Kendo.Mvc

<kendo-timedurationpicker for="Duration" input-mode="numeric">
    <timedurationpicker-columns>
        <timedurationpicker-column name="hours" format="## hours "></timedurationpicker-column>
        <timedurationpicker-column name="minutes" format=" ## minutes"></timedurationpicker-column>
    </timedurationpicker-columns>
</kendo-timedurationpicker>

Notes

The recommended binding type is decimal?.
The unit of the value is milliseconds.
Validation attributes such as [BindProperty] and data annotations like [Required] are supported.
Use the InputMode() and Columns() configuration (or their TagHelper equivalents) to explicitly define how the duration values are displayed.
