About DataGridView control in C#

1. Set Headers:

// Suppose test is an instance of DataGridView control.

test.Columns[i].Name = "Column Header i"; 

test.Columns[i].HeaderText = "Column Header i";

test.Rows[j].HeaderCell.Value = "Row Header j";

 

2. Get the select cell while double clicking mouse. 

test.CellDoubleClick += new DataGridViewCellEventHandler(test_doubleClick);

private void test_doubleClick(object sender, DataGridViewCellEventArgs e)

{

    Console.WriteLine("{0} been clicked! ", test.Rows[e.RowIndex].Cells[e.ColumnIndex].FormattedValue);

}

 

3. Add a new row or delete a row

// newRow is an instance of DataGridViewRow or a string array object that contains all the data in row.

test.Rows.Add(newRow);

test.Rows.RemoveAt(index)
