How to override .ToString() for a collection in DataGrid WPF?

Question

.NET

Hello. WPF. Faced such a problem. I want the datagrid to display the contents of the collection separated by commas instead of "(Collection)".

I tried to make my own class inherited from a regular sheet and overridden .ToList() in it. Then I passed this collection to the datagrid and still - "(Collection)"

public class OrderStringCollection<Orderstring> : List<Orderstring>
    {
        public override string ToString()
        {
            return string.Join(", ", this);
        }
    }

Does anyone have any suggestions on how this can be implemented?

Answer 1

In xaml, use the converter for the field. Like {Binding Orders, Converter={staticres converter}} and in the converter just go through the data you need and create the desired string

Answer 2

You can create a property on a sheet that gives you the desired string, and bind to it.
