Can't edit DataGridView content (even when ReadOnly = false) when clicking on it?

The context here is I use a special kind of DataSource for DataGridView, that is an anonymous type which can be created as follow: ``` var data = new[] { new { A = "A", B = 1 }, new { A = "B", B = 2 }, new { A = "C", B = 3 }}; ``` The problem is if I use the above data source for a DataGridView, I can't edit the content of the DataGridView starting by clicking on its cells. ``` myDataGridView.DataSource = data; ``` Could you please explain to me why and how to make it editable? Or simply we can't make it work that way? Your help would be highly appreciated.
