Hi Son Hoang, 

  

Thanks for your update. 

  

We have validated the reported query and we suggest you to set the selected item based on the item collection to resolve the reported issue as like below code snippet: 

  

Code Snippet: 

  

var item= new ModelItemCombobox() { Key = 1, Value = "Submited" }; 

 

// In this, you can get the item from the items collection based on your column name and set item to selected item. 

 

viewModel.SelectedItems = viewModel.Items.Where(p => p.Value == item.Value).First(); 

picker.SetBinding(SfPicker.SelectedItemProperty,"SelectedItems",BindingMode.TwoWay); 

 

 

  

We have created sample for this and please find the sample from below link
