<controls:PullRefreshProgressControl x:Name="pullRefreshControl" Progress="{Binding RefreshProgress}" RefreshRequested="OnRefreshRequested"/>

private double refreshProgress;
public double RefreshProgress
{
    get { return refreshProgress; }
    set
    {
        refreshProgress = value;
        OnPropertyChanged(nameof(RefreshProgress));
    }
}

private async void OnRefreshRequested(object sender, EventArgs e)
{
    // 执行刷新操作，更新RefreshProgress的值
    RefreshProgress = 0; // 设置进度为0，表示开始刷新

    // 模拟刷新过程，逐渐增加进度值
    for (int i = 0; i <= 100; i += 10)
    {
        RefreshProgress = i;
        await Task.Delay(500); // 模拟耗时操作
    }

    RefreshProgress = 100; // 刷新完成，设置进度为100
}
