UWP SelectionChanged unhandled exception

[Emil]

Hi guy,s

I am seeing sometimes this exception in my sflistview on UWP only. I handle selectinchanged event exceptions as below but this exception is registered as unhandled in uwp. it should be crashing somewhere in the nuget package

    private void list_SelectionChanged(object sender, ItemSelectionChangedEventArgs e)

        {

            try

            {

                 

            }

            catch (Exception ex)

            {

                //report exception

            }

        }

Hi Emil,  

  

Thanks for contacting Syncfusion support.  

  

We have checked the reported query “Exception occurred from the SelectionChanged event” form our side. Unfortunately the reported crash does not replicate at our end. We have prepared the sample based on the provided information. ListView is loaded in the view and selection change happened without any crash.  

  

We have attached the tested sample for your reference and you can download the same from the following link.  

  

Sample: http://www.syncfusion.com/downloads/support/forum/140860/ze/SelectionSample1239843533   

  

Can you please check the reported issue occurs in our sample also? If the sample does not meets you requirement then we would request you to modify the sample to replicate the issue or please share xaml and code behind file which would highly help us to analyze the query better and provide an appropriate solution.

Hi,

Sorry i cant reproduce this exception and I dont even know how to reproduce it because as I showed you, i am having try catch around entire function but this is not registered as an exception in my app center logs but a crash. it means that it crashes in the nuget package while binding UI somewhere. I am seeing it often in my release logs. You should track down using the stacktrace information at least.

thanks,

Emil
