Examples
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;
}
Private Sub DataGridView1_SortCompare( _
ByVal sender As Object, ByVal e As DataGridViewSortCompareEventArgs) _
Handles DataGridView1.SortCompare
' Try to sort based on the contents of the cell 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) AndAlso Not (e.Column.Name = "ID") Then
e.SortResult = System.String.Compare( _
DataGridView1.Rows(e.RowIndex1).Cells("ID").Value.ToString(), _
DataGridView1.Rows(e.RowIndex2).Cells("ID").Value.ToString())
End If
e.Handled = True
End Sub
Remarks
This property is useful when sorting rows based on the cell values in multiple columns.
