using xf 5 and you last main release

the issue seems to be related at this part of xaml (in my code the image source is bounded)

i tried also with a label but i have the same issue.

how to reproduce:

- put a SfCircularGauge inside a a SFlistview or a classic listview

- go to new controller and call MessagingCenter.Send in order to  update the source of the listview

- exception

thanks!

[Luca]

i fixed it adding in SFlistview ListViewCachingStrategy="CreateNewTemplate" and in standard listview CachingStrategy="RecycleElement"

anyway can you have a check please?

thanks

Hi Luca, 

 

We have prepared a sample based on the previously provided replication steps and checked the reported crash in 19.2.0.55 NuGet. But we are afraid that we unable to reproduce the crash from our side. Please get the sample from the below link. 

 

https://www.syncfusion.com/downloads/support/directtrac/general/ze/CircularGauge_Sample-1387780955       

 

Please check the sample. If you still face any problem, can you revert us by modifying the sample based on your scenario, this will help us to provide you a better solution at the earliest.  

 

Regards, 

Eswaran

Hi,

This happens just on android because in iOS is working well. I have a sfList and inside your circular gauge as item ( not alway displayed, depends on logic).

When I clear the items and add new ones from another tab ( the list is in on other tab) I have randomly this error.

Thanks

Hi Luca, 

 

Thanks for your update. 

 

We have checked the reported crash “SfCircularGauge Annotations random exception on android” with the provided replication steps. But we are afraid that we are unable to reproduce it from our side. However, we will include the possible fix in our source level based on the provided stack trace and include the fix in the upcoming weekly NuGet which is expected to be rolled out on September 14, 2021. Please check with it on your end and confirm whether the issue is resolved. 

 

Regards, 

Eswaran.

hi all,

i still have the same issue, it's frustrating.

I'm using your last version and also last version of forms.

i found some interesting things:

1. i'm using the SFlistView with GridLayout
2. i added you code as you wrote here (https://help.syncfusion.com/xamarin/listview/layouts?cs-save-lang=1&cs-lang=csharp#change-span-count-based-on-screen-size )
3. the problem is this  pageWidth != width .I think you added in order to speedup and i agreee, but with this i have the issue. Removing this it works but of course is slow since every time this code is run.

thanks.

here the details.

i have circular gauge as a template in a SFList in a standard xamarin shell app.

If I change the tab and then come back to the tab where there is the list i get this error.

Can you help me? thanks a lot
