SfPullToRefresh doesnt execute on page load

[Enrique]

I have a SfPullToRefresh control and a ActivityIndicator binding to the same viewmodel property (IsRefreshing and IsRunning bindable properties). ActivityIndicator appear on page load, but not SfPullToRefresh.

In other situations works fine. I need remove ActivityIndicator because it is redundant, so I need fix this SfPullToRefresh behavior.

Can you help me please?

Thanks in advance :)

Hi Enrique,  

 

We have checked your reported query for “SfPullToRefresh does not execute on page load”. You can achieve your requirement by calling StartRefreshing method inside BeginInvokeOnMainThread method in the OnAppearing() override, please refer the below code example. 

 

Code snippet 

protected async override void OnAppearing()  

{  

    base.OnAppearing();  

    Device.BeginInvokeOnMainThread(() => {  

        pullToRefresh.StartRefreshing();  

    });  

    await Task.Delay(3000);  

    pullToRefresh.EndRefreshing();  

}

So it´s no possible to manage just from VM?

Im have testing your solution. I can startRefreshing() in onAppearing but I need stop it when my load function in VM has finished, but IsRefreshing = false doesnt work as expected. So I understand is a must stop it with EndRefreshing().

My final workaround has been add a reference to pull to refresh control in VM:

-----------------------------------------------------------

InitializeComponent();

var viewModel = ((MyViewModel)this.BindingContext);

viewModel.PullToRefreshControl = pullToRefresh;

-----------------------------------------------------------

But I dont like this solution. I think IsRefreshing true and false should do the same as StartRefreshing() and EndRefreshin() methods.

Is this feature in the road map?

You have very cool controls, but sometimes help is needed like this time.

Thanks!
