Events in .NET MAUI SfPullToRefresh (SfPullToRefresh)

There are three built-in events in the PullToRefresh control, namely:

  1. Pulling
  2. Refreshing
  3. Refreshed

The Pulling event will be notified whenever the swipe gesture is started. This event will notify the listener each and every time until the refresh content height exceeds. When you release the gesture from pullable content, the Refreshing event will be triggered. Now, the refresh operation can be performed. Once the content is refreshed, set SfPullToRefresh.IsRefreshing to false to stop the animation. Once the animation is stopped, the Refreshed event will be triggered to notify that the refreshing is completed.

Pulling

The Pulling event is triggered whenever you start pulling down on the PullableContent with PullingEventArgs that contains the following properties.

  • Cancel - You can cancel the pulling action based on the Progress value.
  • Progress - Gets the progress completion value.
<syncfusion:SfPullToRefresh x:Name="pullToRefresh" 
                                PullingEvent="OnPullToRefreshPulling" />

pullToRefresh.Pulling += OnPullToRefreshPulling;

    private void OnPullToRefreshPulling(object sender, PullingEventArgs args)
    {
        args.Cancel = false;
        var progress = args.Progress;
    }

Refreshing

The Refreshing event is triggered once the pointer is released. This event will occur till the IsRefreshing property is set as false.

<syncfusion:SfPullToRefresh x:Name="pullToRefresh" 
                                Refreshing="OnPullToRefreshRefreshing" />

pullToRefresh.Refreshing += OnPullToRefreshRefreshing;
   
    private async void OnPullToRefreshRefreshing(object sender, EventArgs args)
    {
        pullToRefresh.IsRefreshing = true;
        await Task.Delay(2000);
        pullToRefresh.IsRefreshing = false;
    }

Refreshed

The Refreshed event is triggered once the Refreshing event is completed.

<syncfusion:SfPullToRefresh x:Name=" pullToRefresh" 
                                Refreshed="OnPullToRefreshRefreshed" />

pullToRefresh.Refreshed += OnPullToRefreshRefreshed;
    
    private void OnPullToRefreshRefreshed(object sender , EventArgs args)
    {
    }
