DataGridViewColumnHeaderCell.SortGlyphDirection 속성

정의

네임스페이스:

System.Windows.Forms

어셈블리:

System.Windows.Forms.dll

표시되는 정렬 문자를 나타내는 값을 가져오거나 설정합니다.

public:
 property System::Windows::Forms::SortOrder SortGlyphDirection { System::Windows::Forms::SortOrder get(); void set(System::Windows::Forms::SortOrder value); };

public System.Windows.Forms.SortOrder SortGlyphDirection { get; set; }

member this.SortGlyphDirection : System.Windows.Forms.SortOrder with get, set

Public Property SortGlyphDirection As SortOrder

속성 값

SortOrder

현재 문자를 나타내는 SortOrder 값입니다. 기본값은 None입니다.

예외

InvalidEnumArgumentException

이 속성을 설정할 때 지정된 값이 유효한 SortOrder 값이 아닙니다.

InvalidOperationException

이 속성을 설정할 때 셀의 OwningColumn 속성 또는 DataGridView 속성 값이 null인 경우

또는

이 속성의 값을 변경할 때 지정된 값이 None이 아니고 소유하고 있는 열의 SortMode 속성 값이 NotSortable인 경우

예제

다음 코드는 프로그래밍 방식으로 속성을 사용하는 SortGlyphDirection 방법을 보여 줍니다.

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 = dataGridView1.SelectedColumns(0)
    Else
        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

End Sub

설명

이 속성은 속성이 로 설정된 열에 SortMode 대해 자동으로 설정됩니다 DataGridViewColumnSortMode.Automatic. 속성이 로 설정된 열을 SortMode 기준으로 정렬할 때 이 속성을 직접 설정 DataGridViewColumnSortMode.Programmatic해야 합니다.
