RadGridView with ItemsSource of ObservableCollection<string> does not allow row additions or edits

Environment

Product Version	2019.1.220
Product	RadGridView for WPF

Description

Since RadGridView is designed to work with collections of business objects, a lot of the core functionality would not work when the ItemsSource of the control is set to a collection of strings.

Solution

In order to avoid that, we can create a simple wrapper class around the string data.

public partial class MainWindow : Window 
{ 
    public MainWindow() 
    { 
        InitializeComponent(); 
 
        var wrappedData = from str in new List<string>() { "one", "two", "three" } 
                          select new StringWrapper { Text = str }; 
 
        this.gridView.ItemsSource = wrappedData; 
    } 
} 
 
public class StringWrapper 
{ 
    public string Text { get; set; } 
}
