public class EditRowViewModel :
An EditRowViewModel object serves as a binding context for a template that defines the presentation of the grid's edit form (EditFormPage).
This example shows how to create a custom view for the grid's edit form and set up the grid to invoke this form when a user double taps a cell.
The grid is bound to a collection of Employee objects and contains columns to display employee information (photo, name, position, phone, address, hire and birth dates, access level, and information about vacation). A custom edit form will display an employee's photo and name, and contain editors to modify employee's phone and address.
Custom Edit Form
Follow the steps below to implement a custom edit form.
Define a data template to be a content for the edit form page. In this example, it is a Xamarin.Forms.Grid with a set of labels and editors inside. Its BindingContext is an EditRowViewModel object. Use its Item property to access an object that represents a data source's record (Employee) and bind editors to its properties.
