Programmatically add new row to WPF DataGrid

Question

I'm trying to add new rows to a DataGrid on a WPF application when clicking on a specific button. This is what I tried so far:

DataGridRow row = new DataGridRow();
table.Items.Add(row); // table = my DataGrid

When I run this code, it throws a System.ArgumentNullException saying

Value cannot be null

What should I do to solve this problem? Thanks in advance.

Agreed you are thinking about tightly coupled Views, change your thinking to views with templates that automatically create rows base on the collection items do not add explicit rows. — JWP, Oct 21 '15 at 21:14

You need to bind your Data Grid's ItemsSource property to a collection of POCO objects and instead of adding Data Grid rows add new POCO objects to that collection and your "problem" will be automagically resolved...

This assumes change notification of your VM properties and implementing INotifyPropertyChanged in your POCO classes of course...
