Property Value

Type: System.Int32

The index of the row containing the second cell.

This property is useful when sorting rows based on the cell values in multiple columns.

The following code example demonstrates the use of RowIndex1 in a multiple column sort. This example is part of a larger example provided in How to: Customize Sorting in the Windows Forms DataGridView Control.

private void dataGridView1_SortCompare(object sender,
    DataGridViewSortCompareEventArgs e)
{
    // Try to sort based on the cells in the current column.
    e.SortResult = System.String.Compare(
        e.CellValue1.ToString(), e.CellValue2.ToString());

    // If the cells are equal, sort based on the ID column.
    if (e.SortResult == 0 && e.Column.Name != "ID")
    {
        e.SortResult = System.String.Compare(
            dataGridView1.Rows[e.RowIndex1].Cells["ID"].Value.ToString(),
            dataGridView1.Rows[e.RowIndex2].Cells["ID"].Value.ToString());
    }
    e.Handled = true;
}
