RadSlideView allows you to attach commands that will be executed when the slide actions occurs. To do this you can use the Commands collection and add a custom SlideViewCommand for each custom action you want to execute.
All the predefined commands within a RadSlideView instance are identified by a member of the SlideViewCommandId enumeration. This is actually the key that relates a command instance to a particular action/routine within the owning slideview. In order to register a custom command within a RadSlideView instance you need to inherit from SlideViewCommand class and override its CanExecute and Execute methods. Following are the members of the CommandId enumerations:
For each of the available commands there is a context object of type [CommandId]CommandContext (namely SlideViewSlidingToIndexCommandContext and SlideViewSlidedToIndexCommandContext) which is passed as a parameter in its Execute method. The context object provides information identical to the corresponding event's args.
This example shows how to add a custom command for the SlidingToIndex action.
First, create a class that inherits from SlideViewCommand and set its Id property accordingly. You would also need to override CanExecute and Execute methods as demonstrated in the example below:
public class CustomSlideViewCommand : SlideViewCommand
this.Id = SlideViewCommandId.SlidingToIndex;
public override bool CanExecute(object parameter)
public override void Execute(object parameter)
var slidedToIndex = (parameter as SlideViewSlidingToIndexCommandContext).Index;
//add your logic here
Application.Current.MainPage.DisplayAlert("", "You're about to go to slide " + slidedToIndex, "OK");
Then add this Command to the Commands collection of the RadSlideView instance:
