Hi Yogita, 

Thank you for your patience. 

We would like to let you know that, setting null to ListView SelectedItem in TapCommand/ItemTapped is not recommended. As per implementation ListView SelectedItem will be set only after TapCommand/ItemTapped is executed, it is the behaviour of SfListView. You can achieve your requirement by using SelectionChanged event.  

We have prepared a sample based on the information provided and you can download the same using the following link, 

Sample Link: SfListViewSample 

Please check the attached sample and let us know if you are still facing the same issue? If yes, please modify our sample and revert us back or share the following details which would be helpful for us to check on it and provide the solution at the earliest.  

•                Xamarin.Forms version and Syncfusion version used in your application. 

•                Specific platform the reported issue reproduced. 

•                Replication procedure to reproduce the issue.
