.NET MAUI TimePicker Commands

The Telerik UI for .NET MAUI TimePicker exposes a number of commands for programmatic manipulation of its popup rendering.

TimePicker Commands

The TimePicker for .NET MAUI exposes the following commands, which enable you to programmatically manipulate the display of the popup and the clearing of the selected item:

• ToggleCommand(ICommand)—Allows you to show and hide the popup. Used for selecting a time value.
• ClearCommand(ICommand)—Allows you to clear the selected time.

The following example shows how to set the ToggleCommand and ClearCommand.

1. Define the TimePicker.

• XAML

<StackLayout>
     <Button Text="Toggle Popup" Command="{Binding Source={x:Reference timePicker}, Path=ToggleCommand}"/>
     <Button Text="Clear Selected Time" Command="{Binding Source={x:Reference timePicker}, Path=ClearCommand}"/>
    <telerik:RadTimePicker x:Name="timePicker" />
</StackLayout>

2. Add the following namespace:

• XAML

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

OK and Cancel Buttons

Through the popup or the drop-down, users can pick a time. The time value must be confirmed or rejected with the OK or Cancel buttons located in the popup or drop-down.

The TimePicker allows you to add a custom logic for the Accept and Cancel commands which are executed when the OK or Cancel buttons are clicked.

• AcceptCommand(ICommand)—Defines the command, which confirms the current selection of the picker and closes the popup or drop-down. Use AcceptCommandParameter to pass a parameter to the command execute method.
• CancelCommand(ICommand)—Defines the command, which rejects the current selection of the picker and closes the popup or drop-down. Use CancelCommandParameter to pass a parameter to the command execute method.

You can apply the Accept and Cancel commands for the popup mode by setting the PopupSettings property of the TimePicker. For the drop-down mode, use the DropDownSettings property.

The following example shows how to set the AcceptCommand and CancelCommand in the PopupSettings. The same is valid for the DropDownSettings.

1. Define the TimePicker with PopupSettings:

• XAML

<telerik:RadTimePicker x:Name="timePicker" PickerMode="Popup">
    <telerik:RadTimePicker.PopupSettings>
        <telerik:PickerPopupSettings AcceptCommand="{Binding Accept}"  
                                     CancelCommand="{Binding Cancel}"/>
    </telerik:RadTimePicker.PopupSettings>
</telerik:RadTimePicker>

2. Add the namespace:

• XAML

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

3. Add a sample ViewModel class:

• C#

public class ViewModel
{
    public ICommand Accept { get; set; }
    public ICommand Cancel { get; set; }

    public ViewModel()
    {
        this.Accept = new Command(this.OnAccept);
        this.Cancel = new Command(this.OnCancel);
    }

    private void OnAccept(object obj)
    {
        // implement your custom logic here
    }

    private void OnCancel(object obj)
    {
        // implement your custom logic here
    }
}
