DataGridViewColumn初始排序方向

Question

我在VS2008上使用C#WinForms应用程序.默认情况下,当单击DataGridView中的列标题时,它会对该列Ascending进行排序,然后您可以再次单击列标题将其排序为Descending.

我试图扭转这一点,所以初始点击排序降序然后第二次点击排序升序,我无法弄清楚如何做到这一点.有人知道吗？

谢谢

Answer 1

您可以将HeaderCell SortGlyphDirection设置为Ascending,然后下一次单击将为您提供降序.默认值为none.

dataGridView1.Sort(Column1, ListSortDirection.Ascending);
this.Column1.HeaderCell.SortGlyphDirection = System.Windows.Forms.SortOrder.Ascending;

Answer 2

foreach (DataGridViewColumn column in DataGridView1.Columns)
{
    column.SortMode = DataGridViewColumnSortMode.Programmatic;
}

和

private void DataGridView1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    var column = DataGridView1.Columns[e.ColumnIndex];
    if (column.SortMode != DataGridViewColumnSortMode.Programmatic)
        return;

    var sortGlyph = column.HeaderCell.SortGlyphDirection;
    switch (sortGlyph)
    {
        case SortOrder.None:
        case SortOrder.Ascending:
            DataGridView1.Sort(column, ListSortDirection.Descending);
            column.HeaderCell.SortGlyphDirection = SortOrder.Descending;
            break;
        case SortOrder.Descending:
            DataGridView1.Sort(column, ListSortDirection.Ascending);
            column.HeaderCell.SortGlyphDirection = SortOrder.Ascending;
            break;
    }
}

我建议下面的代码

MyDGV.Sort(MyDGV.Columns[column_Index], ListSortDirection.Ascending);
