Commands

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

TimeSpanPicker Commands

The TimeSpanPicker 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 interval.
  • ClearCommand(ICommand)—Allows you to clear the displayed time interval.

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

Define the TimeSpanPicker.

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

Add the namespace.

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

PopupSelector Commands

Through the popup, users can pick a time interval. The time interval value has to be confirmed or rejected through the OK and Cancel buttons that are displayed in the popup.

The TimeSpanPicker allows you to add custom logic for the Accept and Cancel commands, which are executed when the OK and Cancel buttons, respectively, are clicked.

  • AcceptCommand(ICommand)—Defines the command which confirms the current selection of the picker and closes the popup.
  • CancelCommand(ICommand)—Defines the command which rejects the current selection of the picker and closes the popup.

You can apply the Accept and Cancel commands by using the SelectorSettings property of TimeSpanPicker.

The following example shows how to set the AcceptCommand and CancelCommand.

  1. Define the TimeSpanPicker.

    <StackLayout>
      <telerik:RadTimeSpanPicker>
          <telerik:RadTimeSpanPicker.SelectorSettings>
              <telerik:PickerPopupSelectorSettings AcceptCommand="{Binding Accept}"
                                                        CancelCommand="{Binding Cancel}"/>
          </telerik:RadTimeSpanPicker.SelectorSettings>
              <telerik:RadTimeSpanPicker.BindingContext>
                  <local:ViewModel/>
              </telerik:RadTimeSpanPicker.BindingContext>
      </telerik:RadTimeSpanPicker>
    </StackLayout>
    
  2. Set the ViewModel.

    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
    }
    }
    
  3. Add the following namespace.

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