While displaying a boolean property, we can use a DataGridCheckboxColumn, which will render a checkbox per item.

As mentioned before, the real power lies in the DataGridTemplateColumn because we can specify how a column will render its contents. We specify a DataTemplate containing the data binding statements for the CellTemplate property. In this template, we can use whichever control we want (for example, a DateTimePicker, an Image, or a ComboBox).

Each column can have a CellTemplate as well as a CellEditingTemplate. When both are specified, the column renders the editing template when the user starts editing its content.

In this editing template, we can offer the user a way to make a selection from several options. We have allowed this using a ComboBox. However, we need some way to bind the list of possible options to this ComboBox. To do so, we can create a helper class that exposes a property that returns a List<T>. We can then instantiate this helper class in XAML and perform a data binding with this instance as the source.
