This looks like a binding issue. Do you see any suspicious messages in VS output window?

Are you sure you are setting the isquantityEditable to false in code behind or in your view model ?

Try to create the DataGridTextColumn in code. So there you can easily set the ReadOnly property.. Example

DataGridTextColumn column=new DataGridTextColumn ();
column.Binding= "bindingName";
column.Header="Your Header";
column.IsReadOnly=True;

Best of Luck.. :-D :-D :-D
