SfAccordion Animation When Calling RaisedPropertyChanged on iOS

[David Bauer]

Hello,

The problem I am facing is when calling RaisedPropertyChanged on my SfAccordion BindableLayout.ItemsSource, the whole accordion gives a refresh animation instead of just adding or removing an item (changing that property). The refresh animation looks like its collapsing all of the items and then exapnding. This only shows on iOS, on Android it looks as expected. Is there a way to prevent this on iOS?

Thank you!

Hello,

I have been able to replicate the issue in the sample you sent me. The reload animation happens when I am trying to change the data inside the accordion. I want the accordion to stay still and only the data to change.

Versions:

Xamarin.Forms – 4.8.0.1687

Syncfusion.Xamarin.SfListView – 18.4.0.33

Syncfusion.Xamarin.Expander – 18.4.0.35

Devices Tested on:

Android – Pixel 3 XL Q 10.0 – API 29

iOS – iPhone 11 pro iOS 14.4

I have attached 2 videos. They are both the same code base tested on iOS and Android. The video of it running on Android is the look I am trying to achieve. The video on iOS shows the reloading animation.

I have also attached the updated sample code.

Thank you.

We have checked the reported query from our end. we would lie to inform you that you can overcome this reported scenario by setting the AnimationDuration has zero in SfAccordion. Please refer to the following code snippet for your reference. 

 

Code Snippet 

<syncfusion:SfAccordion x:Name="Accordion" AnimationDuration="0" BindableLayout.ItemsSource="{Binding Contacts}" ExpandMode="SingleOrNone" > 

    <BindableLayout.ItemTemplate> 

        <DataTemplate> 

            <syncfusion:AccordionItem  > 

                <syncfusion:AccordionItem.Header > 

                    <Grid HeightRequest="60"> 

… 

… 

… 

   </syncfusion:SfAccordion>          

 

Please let us know if you have any concern.

Hi SaiGanesh,

Thank you for your help on this issue. The solution you provided worked to solve the refresh animation problem I was dealing with. However, the SfAccordions now do not show any animation when expanding and collapsing an AccordionItem.

Is there a way that we can fix our original issue but still keep the animation when expanding and collapsing an accordion item?

Thanks!

David

private void button_Clicked(object sender, EventArgs e) 

        { 

            Accordion.AnimationDuration = 0; 

            viewmodel.AddNewAccordionItem(); 

        } 

        private void Accordion_Expanding(object sender, Syncfusion.XForms.Accordion.ExpandingAndCollapsingEventArgs e) 

        { 

            Accordion.AnimationDuration = 150; 

        }
