Question

Funny, how sometimes the simple things bite me in the behind.

I can bind a DataGrid nicely to a Collection of some arbitrary class, using a DataGridTextColumn like this:

// bound to List<Class>
<DataGridTextColumn Header="Name" Binding="{Binding Name}"/>

Now I want to bind a DataGrid to a simple Collection of String. So since there is no property “Name” or something like that to bind to, how do I write the binding:

// bound to List<String>
<DataGridTextColumn Header="Name" Binding="{Binding ???}"/>

String has no Property “Value” or something like that. And if I just write {Binding } I’ll end up with a one-way-binding, unable to write changes back to the Collection.

Thinking about it, I think it is not possible to bind to a collection, so I do need to wrap my string into a class?
Or is there a way?

Answer 1

You can make it run with the following Binding:

Binding="{Binding Path=.}

But it wont solve your problem, because strings are reference typed that are immutable, meaning you cannot change the string reference you have bound to your user interface.

So your thoughts are correct, you will need to wrap these strings in objects, use the path property of Binding and feed these objects to your DataGrid.

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