Awesome controls to add to your Xamarin.Forms apps

Xamarin.Forms Awesome Controls!

I am always working on some really awesome Xamarin.Forms controls and looking to share them with the world. Sometimes they are for 1 platform and sometimes all 3. Check out all of the Awesome Controls and things you can do with Xamarin.Forms :)

These are all experiments So take and implement them in your app understanding they aren't all finished or production ready.

If there is handled exception the spinner does not dissapear

Hello,

if inside my UpdateMenuSettingsExecute() method there is some handled exception (enters in catch block), the spinner does not dissapear...

Here is the source code of the Execute method:

    private async Task UpdateMenuSettingsExecute()
    {
        IsLoadingList = true;

        try
        {
            ShowPickAndPlacement = await _dataService.CallToServer();
        }
        catch (Exception e)
        {
            // manage the exception....
        }

        IsLoadingList = false;
    }

And the code of the view:

<pullToRefresh:PullToRefreshLayout Grid.Row="1" IsPullToRefreshEnabled="True" RefreshCommand="{Binding UpdateMenuSettingsCommand}" IsRefreshing="{Binding IsLoadingList}">
  <ScrollView>

    .... content

  </ScrollView>
</pullToRefresh:PullToRefreshLayout>

Issue with smaller content size

For iOS, it works fine only when the content size inside the pull refresh layout is bigger than the pull refresh layout's size. I tested the sample available on GitHub (scrollview XAML) with fewer boxes/items inside the scroll view e.g. 2. Now when I try to pull the list down, nothing happens.

PullRefreshLayout : Error when setting new MainPage

I am getting an error when trying to set a new MainPage after using the PullRefreshLayout. The object it is trying to use is the ScrollViewRenderer

GifImageView GIF animation

I've consumed GifImageView implementation in my android project.
Gif is basically a loader image which I display whenever any process ongoing and I change visibility of it to display in view.
The problem I'm facing is whenever I change visibility of GifImageView loader image is rotating very fast.
I already try stopanimation and clearanimation but nothing helped.

Is there any workaround for that?

PullToRefreshLayout support for WinRT / Windows 10 apps

Do you have any plans to support pull to refresh for Windows 10 (UWP) apps?

Packages are mising

All the packages that are missing in the project. able to add the packages but not able to find Refactored.GifImageView. Please check with this and update

iOS issue with Forms 1.5.0.6446

Thanks a lot for this layout! It does exactly what I was looking for.

Unfortunately after testing it with Xamarin Forms 1.5.0.6446 there now is a strange rendering issue on iOS: The content of the PullToRefreshLayout is visible in the background when pulled down.

Screenshot:

Do you have any idea how this could be fixed in the iOS renderer?

I pushed a version of your project with the unstable forms version here: https://github.com/philippd/Xamarin.Forms-Awesome-Controls

ListView is not drugging down

After updating XF to 1.3.1 Pull to refresh behavior is strange - I do have an icon of refreshing when pulling the list, but list itself is not pulled and staying still as it is (instead of moving down following the motion).

List get updated and all works fine apart from that.

PullToRefresh It is always being activated .

Hi,

Setting IsPullToRefreshEnabled to false does not work on iOS

If you set IsPullToRefreshEnabled it doesn't seem to do anything. Quite possibly related to the following question on SO - http://stackoverflow.com/questions/19480424/how-do-i-hide-a-uirefreshcontrol

To disable, you need to fully remove the UIRefresh control, not simply set Enabled to false.

Elevation

Hi,
Thanks for your work ! I'd like to use Elevation, to have a shadow like android app.
Could you help me please ?

CardView can't show StackLayout

Works fine with single Label or if I put same StackLayout before it (but then this same StackLayout outside CardView is never shown).
But when I insert StackLayout with some Labels into it it just show empty CardView.
I am quite sure that there is something wrong with the renderer I just can't find out what is it.
I think that there should be some force redraw called on Content of CardView?
I am completely stuck do you have any idea please?

Purpose of IsPullToRefreshEnabledProperty?

Setting IsPullToRefreshEnabledProperty to false seems to not affect anything. You can still pull the refresher down. I was expecting to happen nothing when you try to pull down.
Also the refresher appears even when there is no RefreshCommand set. That makes imo no sense, as it does nothing but showing an animating icon.
