DataGridViewSortCompareEventArgs.RowIndex2 Property

Gets the index of the row containing the second cell to compare.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int RowIndex2 { get; }

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 RowIndex2 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;
}
