Why DataColumn.Caption doesn't work?

Question

I am trying to create a DataTable and bind it to a DataGridView. It works, but I can\'t set columns headers via the Caption property.

Answer 1

            foreach (DataTable dataTable in dataSet.Tables)
        {
            form1.Controls.Add(new LiteralControl(String.Format("
{0}
", dataTable.TableName)));
            GridView grid = new GridView();
            grid.AllowPaging = false;
            grid.AutoGenerateColumns = false;

            foreach (DataColumn col in dataTable.Columns)
            {
                grid.Columns.Add(new BoundField { DataField = col.ColumnName, HeaderText = col.Caption });
            }

            grid.DataSource = dataTable;
            grid.DataBind();

            form1.Controls.Add(grid);
        }
