WPF将datagrid绑定到可观察的字符串集合

Question

I've always binded datagrid to observable collection of classes. Now it should be simpler:

public ObservableCollection<string> obcCodes{ get; set; }

and then

if (obcCodes== null)
    obcCodes= new ObservableCollection<string>();
obcCodes.Add("K2001");
obcCodes.Add("K2002");
obcCodes.Add("K2003");
obcCodes.Add("K2004");

after

dtgCodes.ItemsSource = obcCodes;

so I expected to see those codes in the datagrid instead what I see is:

thanks for any help

Answer 1

As explained here strings are immutable

so you will have to use

    public class StringWrapper { public string Text { get; set; } }

and then use it like that:

    obcCodes.Add(new StringWrapper() { Text = "K2001" });

by doing that you will be able to modify or delete the strings in the datagrid.
