Ejemplos

En el ejemplo de código siguiente se muestra cómo usar la propiedad SortOrder en una ordenación mediante programación.The following code example demonstrates how to use the SortOrder property in a programmatic sort.

private void sortButton_Click(object sender, System.EventArgs e)
{
    // Check which column is selected, otherwise set NewColumn to null.
    DataGridViewColumn newColumn =
        dataGridView1.Columns.GetColumnCount(
        DataGridViewElementStates.Selected) == 1 ?
        dataGridView1.SelectedColumns[0] : null;

    DataGridViewColumn oldColumn = dataGridView1.SortedColumn;
    ListSortDirection direction;

    // If oldColumn is null, then the DataGridView is not currently sorted.
    if (oldColumn != null)
    {
        // Sort the same column again, reversing the SortOrder.
        if (oldColumn == newColumn &&
            dataGridView1.SortOrder == SortOrder.Ascending)
        {
            direction = ListSortDirection.Descending;
        }
        else
        {
            // Sort a new column and remove the old SortGlyph.
            direction = ListSortDirection.Ascending;
            oldColumn.HeaderCell.SortGlyphDirection = SortOrder.None;
        }
    }
    else
    {
        direction = ListSortDirection.Ascending;
    }

    // If no column has been selected, display an error dialog  box.
    if (newColumn == null)
    {
        MessageBox.Show("Select a single column and try again.",
            "Error: Invalid Selection", MessageBoxButtons.OK,
            MessageBoxIcon.Error);
    }
    else
    {
        dataGridView1.Sort(newColumn, direction);
        newColumn.HeaderCell.SortGlyphDirection =
            direction == ListSortDirection.Ascending ?
            SortOrder.Ascending : SortOrder.Descending;
    }
}
Private Sub SortButton_Click(ByVal sender As Object, _
    ByVal e As EventArgs) Handles sortButton.Click

    ' Check which column is selected, otherwise set NewColumn to Nothing.
    Dim newColumn As DataGridViewColumn
    If dataGridView1.Columns.GetColumnCount(DataGridViewElementStates _
        .Selected) = 1 Then

        newColumn = Nothing
    End If

    Dim oldColumn As DataGridViewColumn = dataGridView1.SortedColumn
    Dim direction As ListSortDirection

    ' If oldColumn is null, then the DataGridView is not currently sorted.
    If oldColumn IsNot Nothing Then

        ' Sort the same column again, reversing the SortOrder.
        If oldColumn Is newColumn AndAlso dataGridView1.SortOrder = _
            SortOrder.Ascending Then
            direction = ListSortDirection.Descending
        Else

            ' Sort a new column and remove the old SortGlyph.
            direction = ListSortDirection.Ascending
            oldColumn.HeaderCell.SortGlyphDirection = SortOrder.None
        End If
    Else
        direction = ListSortDirection.Ascending
    End If


    ' If no column has been selected, display an error dialog  box.
    If newColumn Is Nothing Then
        MessageBox.Show("Select a single column and try again.", _
            "Error: Invalid Selection", MessageBoxButtons.OK, _
            MessageBoxIcon.Error)
    Else
        dataGridView1.Sort(newColumn, direction)
        If direction = ListSortDirection.Ascending Then
            newColumn.HeaderCell.SortGlyphDirection = SortOrder.Ascending
        Else
            newColumn.HeaderCell.SortGlyphDirection = SortOrder.Descending
        End If
    End If

Comentarios

Esta propiedad se utiliza para determinar qué glifo de ordenación aparece cuando la columna especificada por la propiedad SortedColumn tiene un valor de propiedad SortMode de Automatic.This property is used to determine which sorting glyph appears when the column specified by the SortedColumn property has a SortMode property value of Automatic. Cuando la columna tiene un valor de propiedad SortMode de Programmatic, debe mostrar y ocultar el glifo de ordenación por medio de la propiedad SortGlyphDirection.When the column has a SortMode property value of Programmatic, you must display and hide the sorting glyph yourself through the SortGlyphDirection property. Cuando la columna tiene un valor de propiedad SortMode de NotSortable, puede mostrar el glifo de ordenación, pero no se reserva espacio para él si se cambia automáticamente el tamaño de la columna.When the column has a SortMode property value of NotSortable, you can display the sorting glyph, but space is not reserved for it if the column is automatically resized.

Nota

El valor de esta propiedad no es significativo al ordenar el control mediante la ordenación personalizada.The value of this property is not meaningful when you sort the control using custom sorting. Para obtener más información sobre la ordenación personalizada, vea el método Sort y el evento SortCompare.For more information about custom sorting, see the Sort method and the SortCompare event.
