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

I came to this thread after researching on the same topic, I found no solution but constructed my own as I desperately needed this one. So here is my solution without going POCO that really works.

// Fill "list" with your dynamic objects.

// cast a dynamic object to dictionary so we get the properties from it.
var props = list[0] as IDictionary;

// create a datatable 
var table = new System.Data.DataTable();
    foreach (var c in props.Keys)
        table.Columns.Add(new DataColumn(c));

foreach (var o in list)
{
    var row = table.NewRow();
    var op =  o as IDictionary;
    foreach (var p in op.Keys)
    {
        row[p] = op[p];
    }
    table.Rows.Add(row);
}

And simply bind this table to your grid!

I tested it and it worked for me.
