RefreshView Pull Direction on Windows

Download Sample Download the sample

This Universal Windows Platform platform-specific enables the pull direction of a RefreshView to be changed to match the orientation of the scrollable control that's displaying data. It's consumed in XAML by setting the RefreshView.RefreshPullDirection bindable property to a value of the RefreshPullDirection enumeration:

<ContentPage ...
    <RefreshView windows:RefreshView.RefreshPullDirection="LeftToRight"
                 IsRefreshing="{Binding IsRefreshing}"
                 Command="{Binding RefreshCommand}">

Alternatively, it can be consumed from C# using the fluent API:

using Xamarin.Forms.PlatformConfiguration;
using Xamarin.Forms.PlatformConfiguration.WindowsSpecific;

The RefreshView.On<Windows> method specifies that this platform-specific will only run on the Universal Windows Platform. The RefreshView.SetRefreshPullDirection method, in the Xamarin.Forms.PlatformConfiguration.WindowsSpecific namespace, is used to set the pull direction of the RefreshView, with the RefreshPullDirection enumeration providing four possible values:

  • LeftToRight indicates that a pull from left to right initiates a refresh.
  • TopToBottom indicates that a pull from top to bottom initiates a refresh, and is the default pull direction of a RefreshView.
  • RightToLeft indicates that a pull from right to left initiates a refresh.
  • BottomToTop indicates that a pull from bottom to top initiates a refresh.

In addition, the GetRefreshPullDirection method can be used to return the current RefreshPullDirection of the RefreshView.

The result is that a specified RefreshPullDirection is applied to the RefreshView, to set the pull direction to match the orientation of the scrollable control that's displaying data. The following screenshot shows a RefreshView with a LeftToRight pull direction:

When you change the pull direction, the starting position of the progress circle automatically rotates so that the arrow starts in the appropriate position for the pull direction.
