var col3 = new DataGridViewTextBoxColumn();
var col4 = new DataGridViewTextBoxColumn();
col3.HeaderText = "Total Number";
col3.Name = "Column3";
col4.HeaderText = "Total Amount";
col4.Name = "Column4";
dataGridView1.Columns.AddRange(new DataGridViewColumn[] { col3, col4 });
我想在数据网格的左端获取两列,即在绑定数据之后。现在我在右端获取新列。我该怎么做?
