Exemples

L’exemple de code suivant illustre l’utilisation Column de dans un tri sur plusieurs colonnes.The following code example demonstrates the use of Column in a multiple column sort. Dans cet exemple, la colonne ID est utilisée pour déterminer l’ordre final s’il existe des valeurs identiques dans la colonne triée. par conséquent, aucun tri supplémentaire n’est effectué s’il existe des valeurs en double dans la colonne ID.In this example the ID column is used to determine the final order if there are identical values in the sorted column, so no additional sorting will be done if there are duplicate values in the ID column. Cet exemple fait partie d’un exemple plus complet fourni dans How to: Personnaliser le tri dans le contrôleDataGridView Windows Forms.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
