Hi Emil, 

 

Sorry for the inconvenience caused. 

 

We have already resolved the similar reported issue (according to provided stack trace) at our end in the 2017 Volume 3 main release. So, could you please check with the latest SfListView version (v15.3.0.29) at your end?. If the issue still persists, then please share the below details which would help us to analyze the issue better and update you an appropriate solution. 

 

• Have you used StickyGroupHeader or StickyHeader and changing the property value at runtime?
• Whether the issue occurs only in specific platform like only in Android platform or in others too?
• Please share the SfListView version in which the issue replicated?
• Have you performed any specific operations at your application? For example: changing the property value in the data model at runtime by which underlying data will move to another group.

 

Please let us know if you require further assistance. 

 

Regards, 

Dinesh Babu Yadav

I am already using this version and experiencing errors time to time. please see my sflistview below. i am executing property change from viewmodel using mvvm and at the same time, it changes selecteditem and should programmaticly scroll to selecteditem. here there can be problem my assumption. see my scrolling implementation. if scrolling fails and i raise property changed when item is not on the screen. I am not sure if this is possible. although I tried to reproduce this case but it didnt happen in my d

Hi Emil, 

 

Sorry for the inconvenience. 

 

Based on the given code snippet and information’s, we have tried to reproduce the reported issue with our sample. In the sample, we have used similar code snippet as provided and changed the CurrentItem (property in View Model) value in a button click event which scroll to selected item in the PropertyChanged event using ScrollToRowIndex method. Unfortunately, we are unable to reproduce the issue at our end. For your reference, we have attached the ensured sample at our end and you can download it from the below link. 

 

Sample: http://www.syncfusion.com/downloads/support/forum/132593/ze/Sample623799590  

 

But according to the given stack trace, we suspect that the issue may occur when a property in underlying data is changed at runtime by which the data moves from one group to another group like similar scenario.  

 

So, could you please share that have you performed any similar scenario like above in your application? If yes, please share the details of that with code examples and if possible, please modify the above sample like your application scenario which would help us to replicate the issue at our end and update you an appropriate solution. 

 

Please let us know if you require further assistance.
