SfPopupLayout - performance issue in complex Page and strange behavior with CollectionView

Hello team

We have a two problems with SfPopupLayout component.

1.) Opening SfPopupLayout depends on complexity of the Page(at least that's what it looks like in my test app). This is problem for us because it takes roughly 2 seconds to open the popup in our production app. You can repeat this if you add some elements on the MainPage in my test app and you can track opening popup time in debug output.

2.) If we use CollectionView like ContentTemplate of SfPopupLayout and remeber this instance(popup is not recreating every time when it is opened) content of popup is not displayed in next opening(only first opening display content). If we change ListView instead of collection view, it works. It only happens on iOS and UWP.

I tested this issue on - iOS -> iPad Mini 4(A1538) Software version: 15.2(19C56) and simulator

UWP -> Windows 10 20H2 (OS Build 19042.1348)

I created test app which is attached. Can you please take a look whether I do something wrong or confirm my theory?

Thanks,

Lukas

Hi Lukas, 

Regarding issue ”Delay in SfPopupLayout opening”. 

We are unable to replicate the reported issue in our end. We are not clear about “You can repeat this if you add some elements on the MainPage in my test app” which you have mentioned in your update. Can you please explain this in detail with issue replication video or image. It will be more helpful for us to find the exact cause for the issue. 

Regarding issue ”CollectionView in SfPopupLayout not renderering in second time” 

We are able to reproduce the reported issue in our end. We are in need of two more business days to validate this properly. We will update the further details on or before January 24, 2022. We appreciate your patience and understanding.  

Regards, 
Suja

Hello Suja,

If you add elements where is commented line in the MainPage.xaml you repeat this issue(check attachment). You can add e.g. 20 elements and track debug output and compare it with time without added elements. There is logged a opening time of popup. If you will add more and more elements, the opening time will be increased. This issue only occurred on iOS. I forgot to mention it before probably. I hope that's clear now.

Regards,

Lukas

Hi Lukas, 

Regarding issue ”Delay in SfPopupLayout opening”. 

We also replicate the same scenario with Xamarin.Forms DisplayAlert, the loading time gets vary slightly based on ContentPage content. The loading time of SfPopup will be based on the elements loaded in SfPopView ContentTemplate.  Please let us know if you need any other assistance. 

Regarding issue ”CollectionView in SfPopupLayout not renderering in second time” .  
             As we already mentioned in our previous update, reported issue occurs with Xamarin.Forms components also without SfPopupLayout control. We also logged the same scenario issue in Xamarin.Forms framework team. Please find the below bug report link for you reference. 


We will you update the further details once we get the proper solution from framework team.

Hello Suja,

Regarding issue ”Delay in SfPopupLayout opening”. 

I understand it depends on ContentTemplate complexity too, but we don't have such complex popup layouts in our app. Anyway, I added scenarios with complex popup layout and simple popup layout and the performance is not so different. Simple popup 50ms, complex popup 100ms -- these measurements are for simple MainPage, running on my iPad (iPad Mini 4 - 2015(A1538)). When the Page gets a little bit more complex, the time for displaying the popup is increasing (even for simple popup layout). For example, I added 30 buttons to the MainPage.xaml and displaying popup took twice as long as before. Imagine a Page where we have a ListView with 12 items visible and each item is composed of ~30 views - in the end, there are hundreds of views on the screen and showing even simple popup takes very long time( ~ 2 seconds).I have attached new version of test app. I want to ask you what options do we have to resolve this issue?

Thank you for your help.

Lukas
