Xamarin Forms Listview set focus to entry on selected row event

I am using the ListView and in each cell I have a label and an entry to the right side. When I click on the entry box the keyboard will show up but if I click on the row without clicking on the entry box the keyboard does not. How can I cause the entry to be focused when its row is selected?
