Is the property on the grid you are binding to Opcode as well?.. if you want to bind directly to List you would just DataSource = list. The databindings allows custom binding. are you trying to do something other than the datasource?
You are getting a bunch of empty rows? do the auto generated columns have names? Have you verified data is in the object (not just string.empty) ?
class MyObject
{
public string Something { get; set; }
public string Text { get; set; }
public string Other { get; set; }
}
public Form1()
{
InitializeComponent();
List<MyObject> myList = new List<MyObject>();
for (int i = 0; i < 200; i++)
{
string num = i.ToString();
myList.Add(new MyObject { Something = "Something " + num , Text = "Some Row " + num , Other = "Other " + num });
}
dataGridView1.DataSource = myList;
}
this should work fine…
