Binding a GridView to a Dynamic or ExpandoObject object

Question

I\'m using Rob Conery\'s Massive ORM, and I haven\'t been able to bind the resulting ExpandoObject to a GridView.

I did find another Stacko

Since you can't bind to an ExpandoObject, you can convert the data into a DataTable. This extension method will do that for you. I might submit this for inclusion to Massive.

/// 

/// Extension method to convert dynamic data to a DataTable. Useful for databinding.
/// 
/// 
/// A DataTable with the copied dynamic data.
public static DataTable ToDataTable(this IEnumerable items) {
    var data = items.ToArray();
    if (data.Count() == 0) return null;

    var dt = new DataTable();
    foreach(var key in ((IDictionary)data[0]).Keys) {
        dt.Columns.Add(key);
    }
    foreach (var d in data) {
        dt.Rows.Add(((IDictionary)d).Values.ToArray());
    }
    return dt;
}
