Add a column to a DataGridView using code

I have a DataGridView connected to a DataSource.

How can I add the following column in code? I can get the column to appear, but it appears with no data in it.

HeaderText: Ref
DataPropertyName: ref
ColumnType: DataGridViewTextBoxColumn

Thanks

If your DataGridView is connected to a DataSource, you have to add the column to the DataSource in order to make the column contain data, and be editable.

Is 'ref' part of the select from the database, that comprise the rest of your DataSource? If so, you could add this column programatically by:
DataGridViewTextBoxColumn col = new DataGridViewTextBoxColumn();
col.DataPropertyName="ref";
col.HeaderText="Ref";
YourDataGridView.Columns.Add(col);
