Xamarin Forms Binding Source Question

Greetings - I am new to Xamarin Forms and am using C# as the backend. I am wanting to create a grid that has a switch grid (what I like to call a toggle button) and 5 fields. I need the data source of those 5 fields to be pulled from a sql server database.

I come from C# background so I am invisioning a datatable set-up that displays all rows that meet the criteria of my Select statement. I have come up with this XAML which meets what I need, however I do not know how to Bind my data to the textboxes.

Can someone here assist me?
