How to edit and save WPF GridView, to database?
<p>I would like to create editable DataGrid whose cells can either be read-only or editable (by DoubleClicking)...
I want to save all of editted cells to database,(via Entity Framework)...</p>

<p>then in some columns, I need to show a combobox instead of a text field.</p>

<p>How do I go about achieving this?</p>
