Hi Fabio, 

Thank you for contacting Syncfusion support. 

We have checked your query. We are unable to reproduce the reported “SelectedItem to null when I change TabItem” in our end. For your reference, we have attached the sample in below location. In the attached sample, the focus is present in the selected item when we move into two different tabs. Could you please refer it.

If you are still facing the issue, could you please revert by modifying the attached sample based on your application along with the replication procedure? This would be helpful for us to provide an appropriate solution.

Hi Fabio, 

 

We have analyzed the issue with provided sample. When switching between the tabs, each time new UserControl being created. You can check this by placing break point in UserContorl constructor. So, each time new SfDataGrid is created when switching tab. So based on the SelectedItem from ViewModel selection rendered in the row with first cell as current cell. It’s not an issue with SfDataGrid.  

 

Please let us know if you have any query.

Hi,
if you substitute within "ucAnimals" user control the sfDataGrid with Microsoft DataGrid, you'll see that SelectedItem is not null and "ucAnimals" will not be recreated.

Hi Fabio,  

Thanks for the update. 

  

We have analyzed your query.  We have substituted the Microsoft DataGrid within the user control, while  navigating from one tab to another tab, each time the UserControl has been recreated and the selected item to be null. The same issue is reproduce in MS dataGrid also.  If the issue is not reproduce in MS dataGrid, could you please provide us a simple video file or replication procedure to reproduce the issue so that it would be more helpful for us to analysis further. 

  

Please let us know if you have any query.
